+
+## Model information
+
+This section describes the MedGemma model and how to use it.
+
+### Description
+
+MedGemma is a collection of [Gemma 3](https://ai.google.dev/gemma/docs/core)
+variants that are trained for performance on medical text and image
+comprehension. Developers can use MedGemma to accelerate building
+healthcare-based AI applications. MedGemma currently comes in two variants: a 4B
+multimodal version and a 27B text-only version.
+
+MedGemma 27B has been trained exclusively on medical text and optimized for
+inference-time computation. MedGemma 27B is only available as an
+instruction-tuned model.
+
+MedGemma variants have been evaluated on a range of clinically relevant
+benchmarks to illustrate their baseline performance. These include both open
+benchmark datasets and curated datasets. Developers can fine-tune MedGemma
+variants for improved performance. Consult the Intended Use section below for
+more details.
+
+A full technical report will be available soon.
+
+### How to use
+
+Below are some example code snippets to help you quickly get started running the
+model locally on GPU. If you want to use the model at scale, we recommend that
+you create a production version using [Model
+Garden](https://cloud.google.com/model-garden).
+
+First, install the Transformers library. Gemma 3 is supported starting from
+transformers 4.50.0.
+
+```sh
+$ pip install -U transformers
+```
+
+**Run model with the `pipeline` API**
+
+```python
+from transformers import pipeline
+import torch
+
+pipe = pipeline(
+    "text-generation",
+    model="google/medgemma-27b-text-it",
+    torch_dtype=torch.bfloat16,
+    device="cuda",
+)
+
+messages = [
+    {
+        "role": "system",
+        "content": "You are a helpful medical assistant."
+    },
+    {
+        "role": "user",
+        "content": "How do you differentiate bacterial from viral pneumonia?"
+    }
+]
+
+output = pipe(text=messages, max_new_tokens=200)
+print(output[0]["generated_text"][-1]["content"])
+```
+
+**Run the model directly**
+
+```python
+# pip install accelerate
+from transformers import AutoTokenizer, AutoModelForCausalLM
+import torch
+
+model_id = "google/medgemma-27b-text-it"
+
+model = AutoModelForCausalLM.from_pretrained(
+    model_id,
+    torch_dtype=torch.bfloat16,
+    device_map="auto",
+)
+tokenizer = AutoTokenizer.from_pretrained(model_id)
+
+messages = [
+    {
+        "role": "system",
+        "content": "You are a helpful medical assistant."
+    },
+    {
+        "role": "user",
+        "content": "How do you differentiate bacterial from viral pneumonia?"
+    }
+]
+
+inputs = tokenizer.apply_chat_template(
+    messages,
+    add_generation_prompt=True,
+    tokenize=True,
+    return_dict=True,
+    return_tensors="pt",
+).to(model.device)
+
+input_len = inputs["input_ids"].shape[-1]
+
+with torch.inference_mode():
+    generation = model.generate(**inputs, max_new_tokens=200, do_sample=False)
+    generation = generation[0][input_len:]
+
+decoded = tokenizer.decode(generation, skip_special_tokens=True)
+print(decoded)
+```
+
+### Examples
+
+See the following Colab notebooks for examples of how to use MedGemma:
+
+*   To give the model a quick try, running it locally with weights from Hugging
+    Face, see [Quick start notebook in
+    Colab](https://colab.research.google.com/github/google-health/medgemma/blob/main/notebooks/quick_start_with_hugging_face.ipynb). Note that you will need to use Colab
+    Enterprise to run the 27B model without quantization.
+
+*   For an example of fine-tuning the model, see the [Fine-tuning notebook in
+    Colab](https://colab.research.google.com/github/google-health/medgemma/blob/main/notebooks/fine_tune_with_hugging_face.ipynb).

+
+### Performance and validation
+
+MedGemma was evaluated across a range of different multimodal classification,
+report generation, visual question answering, and text-based tasks.
+
+### Key performance metrics
+
+#### Text evaluations
+
+MedGemma 4B and text-only MedGemma 27B were evaluated across a range of
+text-only benchmarks for medical knowledge and reasoning.
+
+The MedGemma models outperform their respective base Gemma models across all
+tested text-only health benchmarks.
+
+| Metric | MedGemma 27B | Gemma 3 27B | MedGemma 4B | Gemma 3 4B |
+| :---- | :---- | :---- | :---- | :---- |
+| MedQA (4-op) | 89.8 (best-of-5) 87.7 (0-shot) | 74.9 | 64.4 | 50.7 |
+| MedMCQA | 74.2 | 62.6 | 55.7 | 45.4 |
+| PubMedQA | 76.8 | 73.4 | 73.4 | 68.4 |
+| MMLU Med (text only) | 87.0 | 83.3 | 70.0 | 67.2 |
+| MedXpertQA (text only) | 26.7 | 15.7 | 14.2 | 11.6 |
+| AfriMed-QA | 84.0 | 72.0 | 52.0 | 48.0 |
+
+For all MedGemma 27B results, [test-time
+scaling](https://arxiv.org/abs/2501.19393) is used to improve performance.
+
+### Ethics and safety evaluation
+
+#### Evaluation approach
+
+Our evaluation methods include structured evaluations and internal red-teaming
+testing of relevant content policies. Red-teaming was conducted by a number of
+different teams, each with different goals and human evaluation metrics. These
+models were evaluated against a number of different categories relevant to
+ethics and safety, including:
+
+*   **Child safety**: Evaluation of text-to-text and image-to-text prompts
+    covering child safety policies, including child sexual abuse and
+    exploitation.
+*   **Content safety:** Evaluation of text-to-text and image-to-text prompts
+    covering safety policies, including harassment, violence and gore, and hate
+    speech.
+*   **Representational harms**: Evaluation of text-to-text and image-to-text
+    prompts covering safety policies, including bias, stereotyping, and harmful
+    associations or inaccuracies.
+*   **General medical harms:** Evaluation of text-to-text and image-to-text
+    prompts covering safety policies, including information quality and harmful
+    associations or inaccuracies.
+
+In addition to development level evaluations, we conduct "assurance evaluations"
+which are our "arms-length" internal evaluations for responsibility governance
+decision making. They are conducted separately from the model development team,
+to inform decision making about release. High-level findings are fed back to the
+model team, but prompt sets are held out to prevent overfitting and preserve the
+results' ability to inform decision making. Notable assurance evaluation results
+are reported to our Responsibility & Safety Council as part of release review.
+
+#### Evaluation results
+
+For all areas of safety testing, we saw safe levels of performance across the
+categories of child safety, content safety, and representational harms. All
+testing was conducted without safety filters to evaluate the model capabilities
+and behaviors. For text-to-text, image-to-text, and audio-to-text, and across
+both MedGemma model sizes, the model produced minimal policy violations. A
+limitation of our evaluations was that they included primarily English language
+prompts.
+

+### De-identification/anonymization:
+
+Google and partnerships utilize datasets that have been rigorously anonymized or
+de-identified to ensure the protection of individual research participants and
+patient privacy
+
+## Implementation information
+
+Details about the model internals.
+
+### Software
+
+Training was done using [JAX](https://github.com/jax-ml/jax).
+
+JAX allows researchers to take advantage of the latest generation of hardware,
+including TPUs, for faster and more efficient training of large models.
+
+## Use and limitations
+
+### Intended use
+
+MedGemma is an open multimodal generative AI model intended to be used as a
+starting point that enables more efficient development of downstream healthcare
+applications involving medical text and images. MedGemma is intended for
+developers in the life sciences and healthcare space. Developers are responsible
+for training, adapting and making meaningful changes to MedGemma to accomplish
+their specific intended use. MedGemma models can be fine-tuned by developers
+using their own proprietary data for their specific tasks or solutions.
+
+MedGemma is based on Gemma 3 and has been further trained on medical images and
+text. MedGemma enables further development in any medical context (image and
+textual), however the model was pre-trained using chest X-ray, pathology,
+dermatology, and fundus images. Examples of tasks within MedGemma's training
+include visual question answering pertaining to medical images, such as
+radiographs, or providing answers to textual medical questions. Full details of
+all the tasks MedGemma has been evaluated can be found in an upcoming technical
+report.
+
+### Benefits
+
+*   Provides strong baseline medical image and text comprehension for models of
+    its size.
+*   This strong performance makes it efficient to adapt for downstream
+    healthcare-based use cases, compared to models of similar size without
+    medical data pre-training.
+*   This adaptation may involve prompt engineering, grounding, agentic
+    orchestration or fine-tuning depending on the use case, baseline validation
+    requirements, and desired performance characteristics.
+
+### Limitations
+
+MedGemma is not intended to be used without appropriate validation, adaptation
+and/or making meaningful modification by developers for their specific use case.
+The outputs generated by MedGemma are not intended to directly inform clinical
+diagnosis, patient management decisions, treatment recommendations, or any other
+direct clinical practice applications. Performance benchmarks highlight baseline
+capabilities on relevant benchmarks, but even for image and text domains that
+constitute a substantial portion of training data, inaccurate model output is
+possible. All outputs from MedGemma should be considered preliminary and require
+independent verification, clinical correlation, and further investigation
+through established research and development methodologies.
+
+MedGemma's multimodal capabilities have been primarily evaluated on single-image
+tasks. MedGemma has not been evaluated in use cases that involve comprehension
+of multiple images.
+
+MedGemma has not been evaluated or optimized for multi-turn applications.
+
+MedGemma's training may make it more sensitive to the specific prompt used than
+Gemma 3.
+
+When adapting MedGemma developer should consider the following:
+
+*   **Bias in validation data:** As with any research, developers should ensure
+    that any downstream application is validated to understand performance using
+    data that is appropriately representative of the intended use setting for
+    the specific application (e.g., age, sex, gender, condition, imaging device,
+    etc).
+*   **Data contamination concerns**: When evaluating the generalization
+    capabilities of a large model like MedGemma in a medical context, there is a
+    risk of data contamination, where the model might have inadvertently seen
+    related medical information during its pre-training, potentially
+    overestimating its true ability to generalize to novel medical concepts.
+    Developers should validate MedGemma on datasets not publicly available or
+    otherwise made available to non-institutional researchers to mitigate this
+    risk.
