# Agent Platform Supported Models and Recommendations

This reference catalog provides technical specifications, tuning
recommendations, and deployment hardware requirements for supported models in
Agent Platform.

## Supported Models Catalog

> [!WARNING] **CRITICAL AGENT INSTRUCTION**
> Do NOT use this catalog to recommend a specific model to the user until they
> have explicitly confirmed their **Model Category** as Open Model.
> Furthermore, do NOT recommend any model that is not explicitly listed in this
> catalog, as the tuning service does not support it.

Available open models can be found in Google Cloud [documentation](https://docs.cloud.google.com/gemini-enterprise-agent-platform/models/open-model-tuning#supported-models).
This is the list of open models that are available for tuning; do not suggest
any other open models besides the one listed here.
Each model has some [limitations](https://docs.cloud.google.com/gemini-enterprise-agent-platform/models/open-model-tuning#limitations) for tuning.

## Model Selection Guidelines

**Identify Task**: Check a few samples from the dataset to identify the task.

Choose a model family based on your task type:

- **Qwen**: Best for code generation or complex math-based tasks.
- **Gemma**: Optimized for chat-based interactions, creative writing and multilingual tasks.
- **Llama (Instruct)**: Strong general-purpose chat/instruction models.
- **Llama (Base/Scout)**: Best for continuation tasks or building custom instruction-tuned models.

**Complexity Heuristics**:

- **Simple (QA, Extraction)**: 1B - 3B models.
- **Intermediate (Summarization, Reasoning)**: 8B - 17B models.
- **Complex (Multi-turn, Tool use, Deep reasoning)**: 27B - 70B models.

## Baseline Hyperparameter Recommendations

These values are starting points and should be adjusted based on your dataset
size.
