CrewAI is a lean, standalone Python framework (independent of LangChain) for building multi-agent systems where role-playing autonomous agents collaborate to complete tasks via "crews" and "flows." It is fully model-agnostic: the user brings their own LLM provider API key, supplied through environment variables (OPENAI_API_KEY, ANTHROPIC_API_KEY, GOOGLE_API_KEY, etc.), a YAML config, or the Python LLM class. Through native integrations plus LiteLLM it supports a very broad set of providers and lets users point at any OpenAI-compatible or self-hosted endpoint by setting a custom base_url, including local models via Ollama. It is a developer library/SDK installed via pip and run self-hosted; a separate paid hosted "CrewAI Enterprise/AMP" platform also exists, but the open-source framework itself requires no CrewAI account and uses only the user's own provider keys.

How your API key is handled

Your API key is supplied via an environment variable or local config file. Requests are sent directly to the AI provider. Because it can be self-hosted, your key never has to touch a third-party backend.

Setup

Install the tool, set your provider API key as an environment variable (or in its config file), and pick a model.
