Fine-tune Meta Llama 3.2 text generation models for generative AI inference using Amazon SageMaker JumpStart

Generative AI models have seen tremendous growth, offering cutting-edge solutions for text generation, summarization, code generation, and question answering. Despite their versatility, these models often struggle when applied to niche or domain-specific tasks because their pre-training is typically based on large, generalized datasets. To address these gaps and maximize their utility in specialized scenarios, fine-tuning with domain-specific data is essential to boost accuracy and relevance.

Meta’s newly launched Llama 3.2 series sets a new benchmark in generative AI with its advanced multimodal capabilities and optimized performance across diverse hardware platforms. The collection spans lightweight models like Llama-3.2-1B and Llama-3.2-3B, which support up to 128,000 tokens of context and are tailored for edge devices. These models are ideal for on-device applications such as real-time summarization, instruction following, and multilingual text generation. On the other end of the spectrum, the larger Llama-3.2-11B and Llama-3.2-90B models offer powerful vision-enabled capabilities for tasks such as image understanding, document analysis, and visual grounding. This allows for sophisticated use cases like generating captions for images, interpreting complex graphs, and reasoning over visual data. For instance, the Meta Llama 3.2 models can analyze sales data presented in a graph to provide actionable insights or locate specific objects on a map using natural language instructions.

In this post, we demonstrate how to fine-tune Meta’s latest Llama 3.2 text generation models, Llama 3.2 1B and 3B, using Amazon SageMaker JumpStart for domain-specific applications. By using the pre-built solutions available in SageMaker JumpStart and the customizable Meta Llama 3.2 models, you can unlock the models’ enhanced reasoning, code generation, and instruction-following capabilities to tailor them for your unique use cases. Whether you’re working in finance, healthcare, or any other specialized field, fine-tuning these models will allow you to bridge the gap between general AI capabilities and domain-specific expertise.

Prerequisites

To try out this solution using SageMaker JumpStart, you’ll need the following prerequisites:

Fine-tune Meta Llama 3.2 text generation models

In this section, we demonstrate how to fine-tune Meta Llama 3.2 text generation models. We will first look at the approach of fine-tuning using the SageMaker Studio UI without having to write any code. We then also cover how to fine-tune the model using SageMaker Python SDK.

No-code fine-tuning using the SageMaker Studio UI

SageMaker JumpStart provides access to publicly available and proprietary FMs from third-party and proprietary providers. Data scientists and developers can quickly prototype and experiment with various ML use cases, accelerating the development and deployment of ML applications. It helps reduce the time and effort required to build ML models from scratch, allowing teams to focus on fine-tuning and customizing the models for their specific use cases. These models are released under different licenses designated by their respective sources. It’s essential to review and adhere to the applicable license terms before downloading or using these models to make sure they’re suitable for your intended use case.

You can access the Meta Llama 3.2 FMs through SageMaker JumpStart in the SageMaker Studio UI and the SageMaker Python SDK. In this section, we cover how to discover these models in SageMaker Studio.

SageMaker Studio is an IDE that offers a web-based visual interface for performing the ML development steps, from data preparation to model building, training, and deployment. For instructions on getting started and setting up SageMaker Studio, refer to Amazon SageMaker Studio.

In SageMaker Studio, access SageMaker JumpStart by choosing JumpStart in the navigation pane.
You’re presented with the list of public models offered by SageMaker, where you can explore other models from other providers.

To start using the Meta Llama 3.2 models, under Providers, choose Meta.
You’re presented with a list of the models available.

Choose the Meta Llama 3.2 1B Instruct model.
Here you can view the model details, as well as train, deploy, optimize, and evaluate the model.

For this demonstration, we choose Train.

On this page, you can point to the Amazon Simple Storage Service (Amazon S3) bucket containing the training and validation datasets for fine-tuning.

In addition, you can configure deployment configuration, hyperparameters, and security settings for fine-tuning.
Choose Submit to start the training job on a SageMaker ML instance.

Accept the Llama 3.2 Community License Agreement to initiate the fine-tuning process.

Deploy the model

After the model is fine-tuned, you can deploy it using the model page on SageMaker JumpStart. The option to deploy the fine-tuned model will appear when fine-tuning is finished, as shown in the following screenshot.

Step 8 No-Code Fine-tune Meta Llama 3.2 SageMaker JumpStart

You can also deploy the model from this view. You can configure endpoint settings such as the instance type, number of instances, and endpoint name. You will need to accept the End User License Agreement (EULA) before you can deploy the model.

Step 9 No-Code Fine-tune Meta Llama 3.2 SageMaker JumpStart

Fine-tune using the SageMaker Python SDK

You can also fine-tune Meta Llama 3.2 models using the SageMaker Python SDK. A sample notebook with the full instructions can be found on GitHub. The following code example demonstrates how to fine-tune the Meta Llama 3.2 1B model:

import os
import boto3
from sagemaker.session import Session
from sagemaker.jumpstart.estimator import JumpStartEstimator

# To fine-tune the Llama 3.2 3B model available on JumpStart, please change model_id to `meta-textgeneration-llama-3-2-3b`.
model_id = "meta-textgeneration-llama-3-2-1b"
accept_eula = "true"
estimator = JumpStartEstimator(
    model_id=model_id, environment={"accept_eula": accept_eula}
)

# By default, instruction tuning is set to false. Thus, to use instruction tuning dataset you use instruction_tuned="True"
estimator.set_hyperparameters(instruction_tuned="True", epoch="5", max_input_length = "1024",)
estimator.fit({"training": train_data_location})

The code sets up a SageMaker JumpStart estimator for fine-tuning the Meta Llama 3.2 large language model (LLM) on a custom training dataset. It configures the estimator with the desired model ID, accepts the EULA, enables instruction tuning by setting instruction_tuned="True", sets the number of training epochs, and initiates the fine-tuning process.

When the fine-tuning job is complete, you can deploy the fine-tuned model directly from the estimator, as shown in the following code. As part of the deploy settings, you can define the instance type you want to deploy the model on. For the full list of deployment parameters, refer to the deploy parameters in the SageMaker SDK documentation.

finetuned_predictor = estimator.deploy(instance_type="ml.g5.xlarge")

After the endpoint is up and running, you can perform an inference request against it using the predictor object as follows:

prompt = "Your prompt goes here"
payload = {
        "inputs": prompt,
        "parameters": {"max_new_tokens": 256},
    }
response = finetuned_predictor.predict(payload)
response.get('generated_text')

For the full list of predictor parameters, refer to the predictor object in the SageMaker SDK documentation.

Fine-tuning technique

Language models such as Meta Llama are more than 10 GB or even 100 GB in size. Fine-tuning such large models requires instances with significantly higher CUDA memory. Furthermore, training these models can be very slow due to their size. Therefore, for efficient fine-tuning, we use the following optimizations:

Low-Rank Adaptation (LoRA) – This is a type of parameter efficient fine-tuning (PEFT) for efficient fine-tuning of large models. In this method, we freeze the whole model and only add a small set of adjustable parameters or layers into the model. For instance, instead of training all 3 billion parameters for Meta Llama 3.2 3B, we can fine-tune less than 1% of the parameters. This helps significantly reduce the memory requirement because we only need to store gradients, optimizer states, and other training-related information for only 1% of the parameters. Furthermore, this helps reduce both training time and cost. For more details on this method, refer to LoRA: Low-Rank Adaptation of Large Language Models.
Int8 quantization – Even with optimizations such as LoRA, models like Meta Llama 70B require significant computational resources for training. To reduce the memory footprint during training, we can employ Int8 quantization. Quantization typically reduces the precision of the floating-point data types. Although this decreases the memory required to store model weights, it can potentially degrade the performance due to loss of information. However, Int8 quantization utilizes only a quarter of the precision compared to full-precision training, but it doesn’t incur significant degradation in performance. Instead of simply dropping bits, Int8 quantization rounds the data from one type to another, preserving the essential information while optimizing memory usage. To learn about Int8 quantization, refer to int8(): 8-bit Matrix Multiplication for Transformers at Scale.
Fully Sharded Data Parallel (FSDP) – This is a type of data parallel training algorithm that shards the model’s parameters across data parallel workers and can optionally offload part of the training computation to the CPUs. Although the parameters are sharded across different GPUs, computation of each microbatch is local to the GPU worker. It shards parameters more uniformly and achieves optimized performance through communication and computation overlapping during training.

The following table compares different methods with the two Meta Llama 3.2 models.

Other instance types may also work for fine-tuning. When using p3 instances, training will be done with 32-bit precision because bfloat16 is not supported on these instances. Therefore, the training job would consume double the amount of CUDA memory when training on p3 instances compared to g5 instances.

Training dataset format

SageMaker JumpStart currently support datasets in both domain adaptation format and instruction tuning format. In this section, we specify an example dataset in both formats. For more details, refer to the Dataset formatting section in the appendix.

Domain adaption format

You can fine-tune the Meta Llama 3.2 text generation model on domain-specific datasets, enabling it to generate relevant text and tackle various natural language processing (NLP) tasks within a particular domain using few-shot prompting. This fine-tuning process involves providing the model with a dataset specific to the target domain. The dataset can be in various formats, such as CSV, JSON, or TXT files. For example, if you want to fine-tune the model for the domain of financial reports and filings, you could provide it with a text file containing SEC filings from a company like Amazon. The following is an excerpt from such a filing:

This report includes estimates, projections, statements relating to our
business plans, objectives, and expected operating results that are “forward-
looking statements” within the meaning of the Private Securities Litigation
Reform Act of 1995, Section 27A of the Securities Act of 1933, and Section 21E
of the Securities Exchange Act of 1934. Forward-looking statements may appear
throughout this report, including the following sections: “Business” (Part I,
Item 1 of this Form 10-K), “Risk Factors” (Part I, Item 1A of this Form 10-K),
and “Management’s Discussion and Analysis of Financial Condition and Results
of Operations” (Part II, Item 7 of this Form 10-K). These forward-looking
statements generally are identified by the words “believe,” “project,”
“expect,” “anticipate,” “estimate,” “intend,” “strategy,” “future,”
“opportunity,” “plan,” “may,” “should,” “will,” “would,” “will be,” “will
continue,” “will likely result,” and similar expressions.

Instruction tuning format

In instruction fine-tuning, the model is fine-tuned for a set of NLP tasks described using instructions. This helps improve the model’s performance for unseen tasks with zero-shot prompts. In instruction tuning dataset format, you specify the template.json file describing the input and the output formats and the train.jsonl file with the training data item in each line.

The template.json file always has the following JSON format:

{
  "prompt": "<<Prompt goes here along with question or context or instruction>>",
  "completion": "<<completion goes here depending on the activity, for ex: answer for Q&A or summary for Summarization task>>"
}

For instance, the following table shows the template.json and train.jsonl files for the Dolly and Dialogsum datasets.

Dataset	Use Case	template.json	train.jsonl
Dolly	Question Answering	{ “prompt”: “Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.nn### Instruction:n{instruction}nn### Input:n{context}nn”, “completion”: ” {response}” }	{ “instruction”: “Who painted the Two Monkeys”, “context”: “Two Monkeys or Two Chained Monkeys is a 1562 painting by Dutch and Flemish Renaissance artist Pieter Bruegel the Elder. The work is now in the Gemäldegalerie (Painting Gallery) of the Berlin State Museums.”, “response”: “The two Monkeys or Two Chained Monkeys is a 1562 painting by Dutch and Flemish Renaissance artist Pieter Bruegel the Elder. The work is now in the Gemaeldegalerie (Painting Gallery) of the Berlin State Museums.” }
Dialogsum	Text Summarization	{ “prompt”: “Below is a Instruction that holds conversation which describes discussion between two people.Write a response that appropriately summarizes the conversation.nn### Instruction:n{dialogue}nn”, “completion”: ” {summary}” }	{ “dialogue”: “#Person1#: Where do these flower vases come from? n#Person2#: They are made a town nearby. The flower vases are made of porcelain and covered with tiny bamboo sticks. n#Person1#: Are they breakable? n#Person2#: No. They are not only ornmamental, but also useful. n#Person1#: No wonder it’s so expensive. “, “summary”: “#Person2# explains the flower vases’ materials and advantages and #Person1# understands why they’re expensive.” }

Supported hyperparameters for training

The fine-tuning process for Meta Llama 3.2 models allows you to customize various hyperparameters, each of which can influence factors such as memory consumption, training speed, and the performance of the fine-tuned model. At the time of writing this post, the following are the default hyperparameter values. For the most up-to-date information, refer to the SageMaker Studio console, because these values may be subject to change.

preprocessing_num_workers – The number of processes to use for preprocessing. If None, the main process is used for preprocessing. Default is None.

Instance types and compatible hyperparameters

The memory requirement during fine-tuning may vary based on several factors:

Model type – The 1B model has the smallest GPU memory requirement and the 3B model has a higher memory requirement
Max input length – A higher value of input length leads to processing more tokens at a time and as such requires more CUDA memory
Batch size – A larger batch size requires larger CUDA memory and therefore requires larger instance types
Int8 quantization – If using Int8 quantization, the model is loaded into low precision mode and therefore requires less CUDA memory

To help you get started, we provide a set of combinations of different instance types, hyperparameters, and model types that can be successfully fine-tuned. You can select a configuration as per your requirements and availability of instance types. We fine-tune both two models on a variety of settings with three epochs on a subset of the Dolly dataset with summarization examples.

The results for fine-tuning the models are shown in the appendix at the end of this post. As we can see from these results, fine-tuning improves summarization compared to non-fine-tuned models.

Recommendations on instance types and hyperparameters

When fine-tuning for the model’s accuracy, keep in mind the following:

Larger models such as 3B provide better performance than 1B
Performance without Int8 quantization is better than performance with Int8 quantization

Note the following training time and CUDA memory requirements:

Setting int8_quantization=True decreases the memory requirement.
The combination of per_device_train_batch_size, int8_quantization, and enable_fsdp settings affects the training times. When using a larger batch size with FSDP enabled, the training times are faster compared to using a larger batch size without FSDP.
Decreasing per_device_train_batch_size and max_input_length reduces the memory requirement and therefore can be run on smaller instances. However, setting very low values may increase the training time.
If you’re not using Int8 quantization (int8_quantization=False), use FSDP (enable_fsdp=True) for faster and efficient training.

When choosing the instance type, consider the following:

At the time of writing this post, the G5 instances provided the most efficient training among the supported instance types. However, because AWS regularly updates and introduces new instance types, we recommend that you validate the recommended instance type for Meta Llama 3.2 fine-tuning in the SageMaker documentation or SageMaker console before proceeding.
Training time largely depends on the amount of GPUs and the CUDA memory available. Therefore, training on instances with the same number of GPUs (for example, ml.g5.2xlarge and ml.g5.4xlarge) is roughly the same. Therefore, you can use the more cost-effective instance for training (ml.g5.2xlarge).

To learn about the cost of training per instance, refer to Amazon EC2 G5 Instances.

If your dataset is in instruction tuning format, where each sample consists of an instruction (input) and the desired model response (completion), and these input+completion sequences are short (for example, 50–100 words), using a high value for max_input_length can lead to poor performance. This is because the model may struggle to focus on the relevant information when dealing with a large number of padding tokens, and it can also lead to inefficient use of computational resources. The default value of -1 corresponds to a max_input_length of 1024 for Meta Llama models. We recommend setting max_input_length to a smaller value (for example, 200–400) when working with datasets containing shorter input+completion sequences to mitigate these issues and potentially improve the model’s performance and efficiency.

Lastly, due to the high demand of the G5 instances, you may experience unavailability of these instances in your AWS Region with the error “CapacityError: Unable to provision requested ML compute capacity. Please retry using a different ML instance type.” If you experience this error, retry the training job or try a different Region.

Issues when fine-tuning large models

In this section, we discuss two issues when fine-tuning very large models.

Disable output compression

By default, the output of a training job is a trained model that is compressed in a .tar.gz format before it’s uploaded to Amazon S3. However, for large models like the 70B model, this compression step can be time-consuming, taking more than 4 hours. To mitigate this delay, it’s recommended to use the disable_output_compression feature supported by the SageMaker training environment. When disable_output_compression is set to True, the model is uploaded without any compression, which can significantly reduce the time taken for large model artifacts to be uploaded to Amazon S3. The uncompressed model can then be used directly for deployment or further processing. The following code shows how to pass this parameter into the SageMaker JumpStart estimator:

estimator = JumpStartEstimator(
                                model_id=model_id,
                                environment={"accept_eula": "true"},
                                disable_output_compression=True
                                )

SageMaker Studio kernel timeout issue

The SageMaker Studio kernel is only used to initiate the training job, and its status doesn’t affect the ongoing training process. After the training job starts, the compute resources allocated for the job will continue running the training process, regardless of whether the SageMaker Studio kernel remains active or times out. If the kernel times out during the lengthy training process, you can still deploy the endpoint after training is complete using the training job name with the following code:

from sagemaker.jumpstart.estimator import JumpStartEstimator
training_job_name = <<<INSERT_TRAINING_JOB_NAME>>>

attached_estimator = JumpStartEstimator.attach(training_job_name, model_id)

Conclusion

As generative AI models continue to evolve, their effectiveness hinges on the ability to adapt and specialize for domain-specific applications. Meta’s Llama 3.2 series, with its innovative multimodal features and flexible deployment options, provides a powerful foundation for building tailored AI solutions. By fine-tuning these models using SageMaker JumpStart, organizations can transform generalized capabilities into highly specialized tools, enhancing precision and delivering meaningful results for complex, real-world problems. Whether you’re aiming to improve document analysis, automate visual interpretation, or generate domain-specific content, Meta Llama 3.2 models, fine-tuned to your needs, can bridge the gap between broad AI functionalities and targeted expertise, driving impactful outcomes in your field.

In this post, we discussed fine-tuning Meta Llama 3.2 text generation models using SageMaker JumpStart. We showed that you can use the SageMaker JumpStart console in SageMaker Studio or the SageMaker Python SDK to fine-tune and deploy these models. We also discussed the fine-tuning technique, instance types, and supported hyperparameters. In addition, we outlined recommendations for optimized training based on various tests we carried out.

As shown in the results of fine-tuning the models over two datasets, fine-tuning improves summarization compared to non-fine-tuned models.

As a next step, you can try fine-tuning these models on your own dataset using the code provided in the GitHub repository to test and benchmark the results for your use cases.

Write a response that appropriately completes the request. ### Instruction: What role did Danbury, Connecticut play in the American Revolution? ### Input: During the Revolutionary War, Danbury was an important military supply depot for the Continental Army. Sybil Ludington, 16-year-old daughter of American Colonel Henry Ludington, is said to have made a 40-mile ride in the early hours of the night on April 26, 1777, to warn the people of Danbury and her father’s forces in Putnam County, New York, of the approach of British regulars, helping them muster in defense; these accounts, originating from the Ludington family, are questioned by modern scholars. During the following day on April 26, 1777, the British, under Major General William Tryon, burned and sacked Danbury, but fatalities were limited due to Ludington’s warning. The central motto on the seal of the City of Danbury is Restituimus, (Latin for “We have restored”), a reference to the destruction caused by the Loyalist army troops. The American General David Wooster was mortally wounded at the Battle of Ridgefield by the British forces which had raided Danbury, but at the beginning of the battle, the Americans succeeded in driving the British forces down to Long Island Sound. Wooster is buried in Danbury’s Wooster Cemetery; the private Wooster School in Danbury also was named in his honor. ### Response:	Danbury, Connecticut served as an important military depot for the Continental Army during the revolutionary war. In April 26, 1777 the British Army attacked, burned and sacked the city, but the American troop were able to drive the British forces back to the Long Island sound.

Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request. ### Instruction: Extract the key elements from the paragraph about Apple and list them in bullet points ### Input: Apple Inc. is an American multinational technology company headquartered in Cupertino, California. Apple is the largest technology company by revenue, totaling US$394.3 billion in 2022. As of March 2023, Apple is the world’s biggest company by market capitalization. As of June 2022, Apple is the fourth-largest personal computer vendor by unit sales and second-largest mobile phone manufacturer. It is one of the Big Five American information technology companies, alongside Alphabet (known for Google), Amazon, Meta (known for Facebook), and Microsoft. Apple was founded as Apple Computer Company on April 1, 1976, by Steve Wozniak, Steve Jobs and Ronald Wayne to develop and sell Wozniak’s Apple I personal computer. It was incorporated by Jobs and Wozniak as Apple Computer, Inc. in 1977. The company’s second computer, the Apple II, became a best seller and one of the first mass-produced microcomputers. Apple went public in 1980 to instant financial success. The company developed computers featuring innovative graphical user interfaces, including the 1984 original Macintosh, announced that year in a critically acclaimed advertisement. By 1985, the high cost of its products, and power struggles between executives, caused problems. Wozniak stepped back from Apple amicably and pursued other ventures, while Jobs resigned bitterly and founded NeXT, taking some Apple employees with him. As the market for personal computers expanded and evolved throughout the 1990s, Apple lost considerable market share to the lower-priced duopoly of the Microsoft Windows operating system on Intel-powered PC clones (also known as “Wintel”). In 1997, weeks away from bankruptcy, the company bought NeXT to resolve Apple’s unsuccessful operating system strategy and entice Jobs back to the company. Over the next decade, Jobs guided Apple back to profitability through a number of tactics including introducing the iMac, iPod, iPhone and iPad to critical acclaim, launching the “Think different” campaign and other memorable advertising campaigns, opening the Apple Store retail chain, and acquiring numerous companies to broaden the company’s product portfolio. When Jobs resigned in 2011 for health reasons, and died two months later, he was succeeded as CEO by Tim Cook. Apple became the first publicly traded U.S. company to be valued at over $1 trillion in August 2018, then $2 trillion in August 2020, and $3 trillion in January 2022. As of January 2023, it was valued at around $2.2 trillion. The company receives criticism regarding the labor practices of its contractors, its environmental practices, and its business ethics, including anti-competitive practices and materials sourcing. Nevertheless, the company has a large following and enjoys a high level of brand loyalty. It is ranked as one of the world’s most valuable brands. ### Response:	1.

Write a response that appropriately completes the request. ### Instruction: What is the Indianapolis 500? ### Input: The Indianapolis 500, formally known as the Indianapolis 500-Mile Race, and commonly called the Indy 500, is an annual automobile race held at Indianapolis Motor Speedway (IMS) in Speedway, Indiana, United States, an enclave suburb of Indianapolis. The event is traditionally held over Memorial Day weekend, usually the last weekend of May. It is contested as part of the IndyCar Series, the top level of American open-wheel car racing, a formula colloquially known as “Indy car racing”. The track itself is nicknamed the “Brickyard”, as the racing surface was paved in brick in the fall of 1909. One yard of brick remains exposed at the start/finish line. The event, billed as The Greatest Spectacle in Racing, is considered part of the Triple Crown of Motorsport along with the 24 Hours of Le Mans and the Monaco Grand Prix, with which it typically shares a date. ### Response:	The Indianapolis 500, formally known as the Indianapolis 500-Mile Race, and commonly called the Indy 500, is an annual automobile race held at Indianapolis Motor Speedway (IMS) in Speedway, Indiana, United States, an enclave suburb of Indianapolis.

The event, billed as The Greatest Spectacle in Racing, is considered part of the Triple Crown of Motorsport along with the 24 Hours of Le Mans and the Monaco Grand Prix, with which it typically shares a date. The inaugural race was held in 1911 and was won by Ray Harroun. The event celebrated its 100th anniversary in 2011, and the 100th running was held in 2016. The event was put on hiatus twice, from 1917 to 1918 due to World War I and from 1942 to 1945 due to World War II. In two different periods, the race was part of FIA World Championships; between 1925 and 1928, the World Manufacturers’ Championship and between 1950 and 1960, the World Drivers’ Championship. Marcus Ericsson is the current champion. The most successful drivers are A. J. Foyt, Al Unser Sr., Rick Mears and H√©lio Castroneves, each of whom has won the race four times. The active driver with the most victories is H√©lio Castroneves. Rick Mears holds the record for most career pole positions with six. The most successful car owner is Roger Penske, owner of the Indianapolis Motor Speedway and Team Penske, which has 18 total wins and 18 poles. Penske also has five wins at the IndyCar Grand Prix, held on the combined road course. The event is steeped in tradition, in pre-race ceremonies, post-race celebrations, and race procedure. The most noteworthy and most popular traditions are the 33-car field lining up three-wide for the start, the annual singing of the chorus of “Back Home Again in Indiana,” and the victory lane bottle of milk. Also unique is that qualifying requires the driver to complete four, rather than one, timed laps. Qualifying has a separate weekend. The official attendance is not disclosed by Speedway management, but the permanent seating capacity is upwards of 250,000, and infield patrons raise the race-day attendance to approximately 300,000.

It has been held at the All England Club in Wimbledon, London, since 1877 and is played on outdoor grass courts, with retractable roofs over the two main courts since 2019. ### Response:	The Wimbledon Championships, commonly known simply as Wimbledon, is the oldest tennis tournament in the world and is widely regarded as the most prestigious. It has been held at the All England Club in Wimbledon, London, since 1877 and is played on outdoor grass courts, with retractable roofs over the two main courts since 2019. Wimbledon is one of the four Grand Slam tennis tournaments, the others being the Australian Open, the French Open, and the US Open. Wimbledon is the only major still played on grass, the traditional tennis playing surface. Also, it is the only Grand Slam that retains a night-time curfew, though matches can now continue until 11.00 pm under the lights. The tournament traditionally takes place over two weeks in late June and early July, starting on the last Monday in June and culminating with the Ladies’ and Gentlemen’s Singles Finals, scheduled for the Saturday and Sunday at the end of the second week. Five major events are held each year, with additional junior and invitational competitions also taking place. In 2009, Wimbledon’s Centre Court was fitted with a retractable roof to lessen the loss of playing time due to rain. A roof was operational over No. 1 Court from 2019, when a number of other improvements were made, including adding cushioned seating, a table and 10 independently operable cameras per court to capture the games. Wimbledon traditions include a strict all-white dress code for competitors, and royal patronage. Strawberries and cream are traditionally consumed at the tournament. Unlike other tournaments, advertising is minimal and low key from official suppliers such as Slazenger and Rolex. The relationship with Slazenger is the world’s longest-running sporting sponsorship, providing balls for the tournament since 1902. Due to the COVID-19 pandemic, 2020 Wimbledon was cancelled, the first cancellation of the tournament since World War II. The rescheduled 134th edition was staged from 28 June 2021 to 11 July 2021, following from the 2020 cancellation. The 135th edition was played between 27 June 2022 and 10 July 2022, and regularly scheduled play occurred on the middle Sunday for the first time. It marks the centenary of the inaugural championships staged at the Centre Court. The ATP, ITF, and WTA did not award ranking points for the 2022 tournament, due to controversy over the tournament excluding players representing Russia and Belarus. The 2023 Wimbledon Championships will be the 136th staging and will run from 3 July 2023 to 16 July 2023 and it will be the first event of King Charles III since the death of the former patron, Queen Elizabeth II on 8 September 2022.

Dataset formatting

We currently offer two types of fine-tuning: instruction fine-tuning and domain adaption fine-tuning. You can switch to one of the training methods by specifying the parameter instruction_tuned as True or False.

Domain adaption format

The text generation model can be fine-tuned on any domain-specific dataset to incorporate domain-specific knowledge and language patterns. After fine-tuning on the domain-specific dataset, the model is expected to generate more relevant and accurate text within that domain. Although few-shot prompting can also guide the model towards domain-specific generation, the fine-tuning process plays a crucial role in adapting the model’s understanding and generation capabilities to the target domain. The combination of fine-tuning on domain data and effective prompting techniques can enable the model to perform various NLP tasks within that specific domain more effectively.

For input to the model, use a training and optional validation directory. Each directory contains a CSV, JSON, or TXT file. For CSV and JSON files, the train or validation data is used from the column called text or the first column if no column called text is found. The number of files under train and validation (if provided) should equal to 1, respectively.

The output is a trained model that can be deployed for inference.

The following is an example of a TXT file for fine-tuning the text generation model. The TXT file is SEC filings of Amazon from 2021–2022:

Instruction fine-tuning

The text generation model can be instruction-tuned on any text data provided that the data is in the expected format. The instruction-tuned model can be further deployed for inference. By default, instruction tuning is set to false. Therefore, to use an instruction tuning dataset, you use instruction_tuned="True".

For input, you can use a training and optional validation directory. The training and validation directories should contain one or multiple JSON lines (.jsonl) formatted files. In particular, the train directory can also contain an optional *.json file describing the input and output formats.

The best model is selected according to the validation loss, calculated at the end of each epoch. If a validation set is not given, an (adjustable) percentage of the training data is automatically split and used for validation.

The training data must be formatted in a JSON lines (.jsonl) format, where each line is a dictionary representing a single data sample. All training data must be in a single folder; however, it can be saved in multiple .jsonl files. The .jsonl file extension is mandatory. The training folder can also contain a template.json file describing the input and output formats. If no template file is given, the following template will be used:

{
    "prompt": "Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.nn### Instruction:n{instruction}nn### Input:n{context}nn",
    "completion": "{response}"
}

In this case, the data in the JSON lines entries must include prompt and completion fields. If a custom template is provided, it must also use prompt and completion keys to define the input and output templates. The following is a sample custom template:

{
    "prompt": "question: {question} context: {context}",
    "completion": "{answer}"
}

Here, the data in the JSON lines entries must include the question, context, and answer fields.

The output is a trained model that can be deployed for inference.
