CAMEL is a multi-agent communication framework for building autonomous AI agents that can role-play, collaborate, and solve complex tasks. It provides model backends (OpenAI, Anthropic, DeepSeek, etc.), toolkits, memory, and planning. Current stable version is 0.2.90 (Python 3.10–3.14). Development is active with frequent pre-releases (e.g., 0.2.91a4).

ChatAgent

✓ from camel.agent import ChatAgent

✗ from camel.agent import ChatAgent

Basic ChatAgent example. Requires OPENAI_API_KEY environment variable.

import os from camel.agent import ChatAgent from camel.message import SystemMessage, UserMessage # Set your API key os.environ['OPENAI_API_KEY'] = os.environ.get('OPENAI_API_KEY', 'your-key-here') agent = ChatAgent( system_message=SystemMessage(content="You are a helpful assistant."), model_type="gpt-4o-mini" ) response = agent.step(UserMessage(content="What is the capital of France?")) print(response.msgs[0].content)

Debug

Known issues

breakingAs of v0.2.0, the top-level API was restructured. Many classes moved from `camel.agent` to `camel.agents` (note the 's') and then back. Always check import paths.

fix

Use `from camel.agent import ChatAgent` (singular) for v0.2.90.

affects: >=0.2.0

breakingIn v0.2.50+, `ModelFactory.create()` changed signature; `model_name` parameter was renamed to `model_type`.

fix

Use `ModelFactory.create(model_type='gpt-4o-mini', api_key=...)`.

affects: >=0.2.50

gotchaThe library installs with minimal dependencies by default. Many features (e.g., Anthropic, DeepSeek, web search) require extra installs like `camel-ai[anthropic]`.

fix

Install extras: `pip install 'camel-ai[all]'` or targeted extras like `camel-ai[anthropic]`.

affects: all

gotchaCAMEL uses pydantic v2 for configuration. Mixing pydantic v1 models may cause silent validation failures.

fix

Ensure all pydantic models use v2 syntax (`BaseModel` from `pydantic` not `pydantic.v1`).

affects: >=0.2.0
