autoagents-mistral-rs-metal 0.3.7

Official Python bindings for AutoAgents mistral-rs backend (Metal)

Python Bindings

Repository: https://github.com/liquidos-ai/AutoAgents

The Python bindings exist to make it easy to explore new ideas quickly without giving up the Rust core that powers AutoAgents.

Python stays focused on agent definition, orchestration, experimentation, and callback glue. Rust owns the runtime, scheduling, streaming, concurrency, and core execution model.

Stable vs Experimental

The production path is:

• Rust-owned executors (BasicAgent, ReActAgent)
• Rust-owned memory (SlidingWindowMemory and future Rust-backed providers)
• Python tools
• Python hooks

Explicit extension paths live under autoagents.experimental:

• ExperimentalAgentBuilder
• CustomExecutor
• Python-backed memory adapters

Those extension APIs are experimental in the Python bindings specifically because they rely on Python-native execution or Python-native memory behavior. That boundary exists to keep production runtime ownership in Rust rather than re-centering the architecture on Python callbacks.

The same categories of capability are production-grade in the Rust-native implementation. What is experimental here is the Python extension path, not the underlying AutoAgents model when implemented natively in Rust.

Why This Matters

• Rapid iteration in Python is useful when you are prototyping agent flows, hooks, memory adapters, and pipeline layers.
• Performance-sensitive and safety-critical behavior still comes from the Rust implementation underneath.
• Moving a successful prototype to production Rust is easier because the Python layer is orchestration-oriented rather than a separate runtime.

Practical Outcome

You can prototype in Python with:

• the same LLMProvider model
• the same pipeline composition model
• the same agent builder structure
• the same runtime concepts used by the Rust crates

When you decide to harden something for production, the path to Rust is much smaller because the architecture is already aligned.

Installation from PyPI

Install the base package:

pip install autoagents-py

Install with a local backend or guardrails using extras:

pip install "autoagents-py[llamacpp]"           # llama.cpp CPU
pip install "autoagents-py[llamacpp-cuda]"      # llama.cpp CUDA
pip install "autoagents-py[llamacpp-metal]"     # llama.cpp Metal (macOS)
pip install "autoagents-py[llamacpp-vulkan]"    # llama.cpp Vulkan
pip install "autoagents-py[mistralrs]"          # mistral-rs CPU
pip install "autoagents-py[mistralrs-cuda]"     # mistral-rs CUDA
pip install "autoagents-py[mistralrs-metal]"    # mistral-rs Metal (macOS)
pip install "autoagents-py[guardrails]"         # Guardrails
pip install "autoagents-py[llamacpp-cuda,guardrails]"  # Multiple extras

Local Development

From the repository root:

uv venv --python=3.12
source .venv/bin/activate
uv pip install -U pip maturin pytest pytest-asyncio pytest-cov

make python-bindings-build

For local backend work:

make python-bindings-build-llamacpp-only
make python-bindings-build-mistralrs-only

Backend-specific distributables now live in dedicated package directories under bindings/python/ such as autoagents-llamacpp-cuda and autoagents-mistralrs-metal, so local builds and release builds use the same checked-in package metadata.
