+# AGENTS
+
+This file provides instructions for AI agents to understand the layout of the `mistral.rs` repository, run builds/tests, and follow project conventions.
+
+## Repository Structure
+
+- `/mistralrs/`           : Main Rust crate (text & multimodal inference API)
+- `/mistralrs-core/`      : Core inference logic and tensor operations (text models)
+- `/mistralrs-vision/`    : Vision inference support (image-based inputs & vision-enabled models)
+- `/mistralrs-quant/`     : Quantization support (ISQ, GGUF, GPTQ, AWQ, FP8, HQQ, etc.)
+- `/mistralrs-paged-attn/`: PagedAttention implementation
+- `/mistralrs-pyo3/`      : Python bindings (PyO3)
+- `/mistralrs-server/`    : CLI & OpenAI-compatible HTTP server (subcommands: run/vision-plain, diffusion, speech)
+- `/mistralrs-server-core/`: Shared server core logic
+- `/mistralrs-web-chat/`  : Web chat application (static assets & backend integration)
+- `/mistralrs-bench/`     : Benchmarking tools
+- `/docs/`                : Markdown documentation for models, features, and guides
+- `/examples/`            : Usage examples (Rust, Python, server samples, notebooks)
+- `/chat_templates/`      : Chat formatting templates (JSON/Jinja)
+- `/scripts/`             : Utility scripts (e.g., AWQ conversion)
+  
+## Feature Organization
+
+Mistral.rs supports multiple model types and advanced features via dedicated crates and CLI subcommands:
+
+- **Text Inference**
+  - Crate: `mistralrs-core` (low-level ops), `mistralrs` (API wrapper)
+  - CLI: `run` / `plain` subcommand in `mistralrs-server`
+  - Docs: `docs/SAMPLING.md`, `docs/TOOL_CALLING.md`
+- **Vision Models**
+  - Crate: `mistralrs-vision`
+  - CLI: `vision-plain` subcommand
+  - Docs: `docs/VISION_MODELS.md`, `docs/IMAGEGEN_MODELS.md`, `docs/IMATRIX.md`
+- **Diffusion Models**
+  - CLI: `diffusion` subcommand
+  - Docs: `docs/FLUX.md`
+- **Speech Models**
+  - CLI: `speech` subcommand
+  - Docs: `docs/DIA.md`
+- **Quantization & ISQ**
+  - Crate: `mistralrs-quant`
+  - Docs: `docs/QUANTS.md`, `docs/ISQ.md`
+  - Conversion Script: `scripts/convert_awq_marlin.py`
+- **Paged Attention**
+  - Crate: `mistralrs-paged-attn`
+  - Docs: `docs/PAGED_ATTENTION.md`
+- **Adapters & LoRA/X-LoRA**
+  - Docs: `docs/ADAPTER_MODELS.md`, `docs/LORA_XLORA.md`
+- **Mixture of Experts (AnyMoE)**
+  - Docs: `docs/ANYMOE.md`
+
+## Building
+
+1. Install Rust via rustup (Rust 2021 edition).
+2. Choose optional features (e.g., `cuda`, `flash-attn`, `cudnn`, `metal`, `mkl`, `accelerate`).
+3. Build the entire workspace:
+   ```bash
+   cargo build --workspace --release --features "<features>"
+   ```
+4. Or build/install only the server binary:
+   ```bash
+   cargo build --release --package mistralrs-server --features "<features>"
+   cargo install --path mistralrs-server --features "<features>"
+   ```
+
+## Testing
+
+- Core test suite (requires HF token for some tests):
+  ```bash
+  export HF_TOKEN=<your_token>  # or TESTS_HF_TOKEN for CI parity
+  cargo test -p mistralrs-core -p mistralrs-quant -p mistralrs-vision
+  ```
+- Run all tests across workspace (may skip some crates without tests):
+  ```bash
+  cargo test --workspace
+  ```
+
+## Formatting & Linting
+
+- Format all Rust code:
+  ```bash
+  cargo fmt --all
+  make fmt       # also formats Python/CUDA/C++ files via ruff, clang-format
+  ```
+- Lint with Clippy:
+  ```bash
+  cargo clippy --workspace --tests --examples -- -D warnings
+  ```
+
+## Documentation
+
+- Generate Rust docs for all crates:
+  ```bash
+  cargo doc --workspace
+  ```
+- Preview at `target/doc/` or publish to GitHub Pages as configured.
+- Refer to `/docs/` for in-depth markdown guides (e.g., DEVICE_MAPPING.md, TOOL_CALLING.md).
+
+## Examples
+
+- Rust examples: `mistralrs/examples/`
+- Python examples: `examples/python/`
+- Server samples: `examples/server/`
+- Run Python scripts:
+  ```bash
+  python3 examples/python/<script>.py
+  ```
+- Run server/CLI:
+  ```bash
+  ./target/release/mistralrs-server -i <mode> -m <model> [options]
+  ```
+
+## CI Parity
+
+The CI pipeline is defined in `.github/workflows/ci.yml` and includes:
+  - `cargo check` for all targets
+  - `cargo test` on core crates
+  - `cargo fmt -- --check`
+  - `cargo clippy -D warnings`
+  - `cargo doc`
+  - Typos check (`crate-ci/typos`)
+
+## Contribution Conventions
+
+- Follow Rust 2021 idioms, keep code minimal and focused.
+- Update `/docs/` and examples when adding features or breaking changes.
+- Add tests and examples for new functionality.
+- Commit messages should be clear and follow conventional style where possible.
+  ```
+  feat(crate): describe new feature
+  fix(crate): describe bug fix
+  docs: update docs for ...
+  ```
