  OpenWorker
 A desktop AI coworker, built on aisuite — now in its own repository: andrewyng/openworker.

 OpenWorker chats, does deep research, and carries out real tasks on your computer — reading files with
 permission, connecting to Slack/email, producing PDFs, documents, and spreadsheets, and running scheduled
 automations. Bring your own API key (OpenAI, Anthropic, Google) or run fully local with Ollama; your data
 stays on your machine.

 OpenWorker development has moved to the new repo. A historical snapshot of its source remains in openworker-archive/.



  aisuite




aisuite is a lightweight Python library for building with LLMs, in two layers: a unified Chat Completions API across providers, and an Agents API with tools and toolkits on top. aisuite also powers OpenWorker, a desktop AI coworker developed in its own repository:

 Chat Completions API — a unified, OpenAI-style interface for OpenAI, Anthropic, Google, Mistral, Hugging Face, AWS, Cohere, Ollama, OpenRouter, Requesty, and more. Swap providers by changing one string.
 Agents API · Toolkits · MCP — give models real Python functions as tools, run multi-turn loops, attach ready-made toolkits (files, git, shell) or any MCP server, and govern it all with tool policies.
 OpenWorker — a desktop AI coworker built using aisuite, shipped as an app for everyday tasks. Developed in its own repository.

 Installation

Install the base package, or include the SDKs of the providers you plan to use:

shell
pip install aisuite                base package, no provider SDKs
pip install 'aisuite[anthropic]'   with a specific provider's SDK
pip install 'aisuite[all]'         with all provider SDKs


You'll also need API keys for the providers you call — the Chat Completions quickstart covers key setup and your first calls.

 Chat Completions — one API across providers

The chat API provides a high-level abstraction for model interactions. It supports all core parameters (temperature, max_tokens, tools, etc.) in a provider-agnostic way, and standardizes request and response structures so you can focus on logic rather than SDK differences.

Model names use the format :; aisuite routes the call to the right p
