Overview

AutoAgents is a modular, multi-agent framework for building intelligent systems in Rust. It combines a type-safe agent model with structured tool calling, configurable memory, and pluggable LLM backends. The architecture is designed for performance, safety, and composability across server, edge.

---

Key Features

• Agent execution: ReAct and basic executors, streaming responses, and structured outputs
• Tooling: Derive macros for tools and outputs, plus a sandboxed WASM runtime for tool execution
• Memory: Sliding window memory with extensible backends
• LLM providers: Cloud and local backends behind a unified interface
• LLM Guardrails: Guardrail implementation for safeguarding LLM inference
• LLM Optimization: Build LLM pipelines with optimization passes like cache and retry for faster, more reliable inference
• Multi-agent orchestration: Typed pub/sub communication and environment management
• Speech-Processing: Local TTS and STT support
• Observability: OpenTelemetry tracing and metrics with pluggable exporters

Installation

Prerequisites

• Rust (latest stable recommended)
• Cargo package manager
• LeftHook for Git hooks management
• Python 3.9+ (required for Python bindings)
• uv for Python environment and package management
• maturin (required to build/install local Python bindings from source)

Prerequisite

sudo apt update
sudo apt install build-essential libasound2-dev alsa-utils pkg-config libssl-dev -y

Install LeftHook

macOS (Homebrew):

brew install lefthook

Linux/Windows (npm):

npm install -g lefthook

Clone and Build

git clone https://github.com/liquidos-ai/AutoAgents.git
cd AutoAgents
lefthook install
cargo build --workspace --all-features

Python Bindings

AutoAgents ships Python bindings to PyPI. Install the base package and add backends via extras:

pip install autoagents-py                            # core + cloud LLM providers
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]"  # combine extras

Development install from this repo:

uv venv --python=3.12
source .venv/bin/activate          # Windows: .venv\Scripts\activate
uv pip install -U pip maturin pytest pytest-asyncio pytest-cov

# Clean, build, and install all CPU bindings into the active venv
make python-bindings-build

# Clean, build, and install CPU + CUDA bindings
make python-bindings-build-cuda

The Make targets remove stale editable-install extension artifacts before rebuilding, which avoids loading out-of-date .abi3.so files from the source tree.

Example scripts:

• Core cloud example: bindings/python/autoagents/examples/openai_agent.py
• llama.cpp example: bindings/python/autoagents-llamacpp/examples/llamacpp_agent.py
• mistral-rs example: bindings/python/autoagents-mistralrs/examples/mistral_rs_agent.py

cargo test --features "full" --workspace
