Today, we’re excited to announce that the Gemma model is now available for customers using Amazon SageMaker JumpStart. Gemma is a family of language models based on Google’s Gemini models, trained on up to 6 trillion tokens of text. The Gemma family consists of two sizes: a 7 billion parameter model and a 2 billion parameter model. Now, you can use Gemma 2B and Gemma 7B pretrained and instruction-tuned models within SageMaker JumpStart. JumpStart is the machine learning (ML) hub of SageMaker that provides access to foundation models in addition to built-in algorithms and end-to-end solution templates to help you quickly get started with ML.
In this post, we walk through how to deploy the Gemma model and fine tune it for your use cases in SageMaker JumpStart. The complete notebook is available on GitHub.
Gemma model
Gemma is a family of lightweight, state-of-the-art models built from the same research and technology used to create the Gemini models. Developed by Google DeepMind and other teams across Google, Gemma is inspired by Gemini. Gemma exhibits strong generalist capabilities in text domains and state-of-the-art understanding and reasoning skills at scale. It achieves better performance compared to other publicly available models of similar or larger scales across different domains, including question answering, commonsense reasoning, mathematics and science, and coding. Gemma released the model weights to support developer innovation using Gemma models. Gemma was launched with a new Responsible Generative AI Toolkit that provides guidance and essential tools for creating safer AI applications with Gemma.
Foundation models in SageMaker
JumpStart provides access to a range of models from popular model hubs including Hugging Face, PyTorch Hub, and TensorFlow Hub, which you can use within your ML development workflow in SageMaker. Recent advances in ML have given rise to a new class of models known as foundation models, which are typically trained on billions of parameters and are adaptable to a wide category of use cases, such as text summarization, generating digital art, and language translation. Because these models are expensive to train, customers want to use existing pre-trained foundation models and fine-tune them as needed, rather than train these models themselves. SageMaker provides a curated list of models that you can choose from on the SageMaker console.
You can now find foundation models from different model providers within JumpStart, enabling you to get started with foundation models quickly. You can find foundation models based on different tasks or model providers, and review model characteristics and usage terms. You can also try these models using a test UI widget. When you want to use a foundation model at scale, you can do so without leaving SageMaker by using pre-built notebooks from model providers. Because the models are hosted and deployed on AWS, your data, whether used for evaluating the model or using it at scale, is never shared with third parties.
Let’s explore how you can use the Llama Guard model in JumpStart.
Explore the Gemma model in Jumpstart
You can access Gemma foundation models through SageMaker JumpStart in the SageMaker Studio UI and the SageMaker Python SDK. In this section, we go over how to discover the models in SageMaker Studio.
SageMaker Studio is an integrated development environment (IDE) that provides a single web-based visual interface where you can access purpose-built tools to perform all ML development steps, from preparing data to building, training, and deploying your ML models. For more details on how to get started and set up SageMaker Studio, see Amazon SageMaker Studio.
In the AWS Management Console for SageMaker Studio, go to SageMaker JumpStart under Prebuilt and automated solutions. Jumpstart contains pre-trained models, notebooks, and prebuilt solutions.
On the SageMaker JumpStart landing page, you can find the Gemma model by searching for Gemma.
You can then select from a variety of Gemma model variants, including Gemma 2B, Gemma 7B, Gemma 2B instruct, and Gemma 7B instruct.
Choose the model card to view details about the model such as the license, data used to train, and how to use the model. You will also find a Deploy button, which takes you to a landing page where you can test inference with an example payload.
Deploy Gemma with SageMaker Python SDK
You can find the code showing the deployment of Gemma on JumpStart and an example of how to use the deployed model in this GitHub notebook.
Start by selecting the SageMaker Model Hub model ID and model version to use when deploying Gemma.
Choose a model ID from the following table, which details the default configuration options for the JumpStart deployment. Because of the large vocabulary size of 256 thousand tokens, Gemma 7B can only fit on a single A10G GPU when supporting a 1 thousand context length. For this reason, JumpStart uses a larger default instance for Gemma 7B.

You can now deploy the model using SageMaker JumpStart. The following code uses the default instance ml.g5.12xlarge for the inference endpoint You can deploy the model on other instance types by passing instance_type in the JumpStartModel class. The deployment might take 5-10 minutes.
For successful deployment, you must manually change the accept_eula argument in the model’s deploy method to True. This model is deployed using the text-generation-inference (TGI) deep learning container.
Invoke endpoint
You can programmatically retrieve example payloads from the JumpStartModel object. This will help you get started by observing pre-formatted instruction prompts that Gemma can ingest.
Before we look at specific prompts, let’s consider the chat template for Gemma Instruct models.
Here, you place your prompt in the [USER_PROMPT] location. There’s no support for a system instruction; instead, you can prepend the desired instruction to the user prompt. Additionally, if you have a multi-turn conversation, then the model prompt can alternate between user and assistant as needed.
Now consider a few instruction example prompts. Here, you ask Gemma to write a Hello World program.
The following is the expected output:
Next, invoke Gemma for the creative task of writing a poem.
The following is the output:
This looks pretty good!
Now, let’s look at latency and throughput performance benchmarking for model serving with the default JumpStart deployment configuration. Here, we show how model performance might differ for your typical endpoint workload. In the following tables, you can observe that small-sized queries (256 input words and 256 output tokens) are quite performant under a large number of concurrent users, reaching token throughput on the order of one thousand to two thousand tokens per second. However, as the number of input words approaches Gemma’s maximum supported context length of eight thousand tokens, the endpoint saturates its batching capacity—the number of concurrent requests allowed to be processed simultaneously—due to instance memory-bound constraints.
For more information on how to consider this information and adjust deployment configurations for your specific use case, see Benchmark and optimize endpoint deployment in Amazon SageMaker JumpStart.

Fine-tune Gemma using SageMaker Python SDK
Next, we show you how to fine-tune the Gemma 7B instruct model on a conversational-formatted dataset using QLoRA technique. As mentioned previously, due to the large vocabulary size of 256 thousand and the 8 thousand context length, JumpStart offers the following default configurations for QLoRA fine-tuning.

Let’s load and process the dataset in conversational format. The example dataset for this demonstration is OpenAssistant’s TOP-1 Conversation Threads.
The training data should be formulated in JSON lines (.jsonl) format, where each line is a dictionary representing a set of conversations. One example within the JSON lines file is shown below. For details on how to process the dataset, see the notebook in GitHub.
Underlying the training scripts, JumpStart uses HuggingFace SFTTrainer with QLoRA and FlashAttention. Flash Attention enables scaling efficiency, leading to faster training and inference. Besides chat-based fine-tuning, JumpStart also supports instruction and domain adaptation fine-tuning with QLoRA. For details, see the notebook in GitHub.
After the fine-tuning, you can deploy the fine-tuned model to a SageMaker endpoint.
You can choose to deploy the model fine-tuned on conversation data in SageMaker endpoint with HuggingFace messages API feature as an alternative approach. The benefit of using Message API feature is that it allow users to pass the query examples in raw format as shown in the following table and chat_template within the endpoint will convert the query examples into the proper format before sending them into the model. For details, see the deployment section after fine-tuning in the notebook.
After deploying the fine-tuned model in an endpoint, you can compare output responses from pre-trained and fine-tuned Gemma models. The examples are collected from test data, which is a hold-out set from the training data. The inference parameters are max_tokens as 512, top_p as 0.9, temperature as 0.4, and top_k as 50.
As you can see with the fine tuning results, the agent answers are more accurate.
To further evaluate your fine tuned models, you may explore FM evaluation with Amazon SageMaker Clarify to see how your fine tuned model performs in comparison to base model.

User: Give me a list of to do items when starting a project to train a large language model that can understanding and respond to human questions
Assistant: The following steps are a condensed list of steps to take when starting a project to train a large language model capable of comprehending and responding to human inquiries:
1. Establish project scope and objectives, target audience.
2. Gather and preprocess a comprehensive/diverse text dataset.
3. Select an appropriate model architecture, adjust hyperparameters for accuracy/speed.
4. Divide dataset into training, validation, testing subsets, implement data augmentation.
5. Train model, monitor progress on validation set, adjust as needed.
6. Evaluate model on test set, compare to benchmarks, analyze errors and biases.
7. Fine-tune for specific tasks or domains through transfer learning or fine-tuning.
8. Create interface for user input and model response.
9. Test in controlled environment, gather feedback for improvement.
10. Continuously monitor and improve performance through retraining and fine-tuning.
This should give you a basic idea of what the required steps are. Should I go into more detail on one of the points?
User: These tasks need to be broken down further, could you please provide an updated to-do list with a more detailed breakdown of the tasks ahead
Assistant: Here is a more detailed breakdown of each step:
1. Establish project scope and objectives: It is important to clearly define the goals of the project and what the target audience is. This will help you make decisions about what type of data to gather and what model architecture is appropriate.
2. Gather and preprocess data: This is an important step as the quality and diversity of the data will directly impact the performance of the model. Preprocessing may involve cleaning the data, tokenizing text, and converting words to numerical representations.
3. Select model architecture: There are many different types of models to choose from, including recurrent neural networks (RNNs), transformer models, and convolutional neural networks (CNNs). The choice will depend on the specific requirements of the project and the amount of data available.
4. Divide dataset and implement data augmentation: Splitting the data into training, validation, and testing subsets is important for monitoring the performance of the model during training. Data augmentation can be used to artificially increase the size of the dataset and improve the robustness of the model.
5. Train model and monitor progress: This step involves training the model on the training data, using the validation set to monitor progress and adjust hyperparameters as needed. It may be necessary to repeat this process several times until the model is performing well on the validation set.
6. Evaluate model on test set: Once the model is trained, it’s important to evaluate its performance on a separate test set to get an idea of its generalization ability. This can be done by comparing the model’s predictions to the actual outcomes and analyzing the errors.
7. Fine-tune for specific tasks or domains: This step involves further training the model on task-specific data to improve its performance for a particular domain. This can be done through transfer learning, where a pre-trained model is fine-tuned on new data, or through fine-tuning, where the model is trained from scratch on the new data.
8. Create an interface for user input: This involves designing an interface that allows users to input questions or requests, and receive responses from the model.
9. Test in controlled environment: Before deploying the model in a real-world setting, it’s important to test it in a controlled environment and gather feedback from users. This will help identify any errors or biases in the model and provide opportunities for improvement.
10. Continuously monitor and improve performance: Finally, it is important to continuously monitor the performance of the model and make updates and improvements as needed. This may involve retraining the model on new data, fine-tuning hyperparameters, or updating the architecture.
