v0.6.0: Breakpoint Recovery, Serialization and Deserialization, Gemini and Open LLMs Support

Release Highlights

Numerical statistics

• Huge number of commits: increased from ~1300 to ~2000
• Significantly improved test coverage: from ~30% to 80%+

Ease of use

• Example simplification: Now only 7 lines of code are needed to implement a general election debate. Simplified debate and knowledge base related examples
• Pure asynchronous: LLM API calls are changed to pure asynchronous, removing all synchronization code

Framework update

• Integrated code to support Huggingface demo and AgentStore
• Added serialization and deserialization of important objects
• Supported breakpoint recovery
• All types modified to base on pydantic v2. In order to keep it simple enough, all private variables are changed to public
• Moved most logic of ActionOutput to ActionNode

LLM provider update

• OpenAI package upgraded to v1.6.0
• Supported or optimized LLMs: Gemini, ZhipuAI, Ollama, and other Open LLMs etc.

Other update

• Removed OpenInterpreter and StableDiffusion part of the code
• Added ToT strategy
• Installation process optimized: now you can use pip install -e .[dev] / pip install -e .[test] to install the package corresponding to the scenario

What's Changed

Backwards Incompatible Changes

• IMPORTANT: In accordance with OpenAI's official specifications, the OPENAI_API_BASE has been renamed to OPENAI_BASE_URL in config.yaml
• The underlying abstraction has been renamed from BaseGPTAPI to BaseLLM, making it more generic and capable of supporting API / UI / local interfaces.
• Role._rc -> Role.rc
• Removed BaseLLM.ask and BaseLLM.ask_code, maintained the asynchronous BaseLLM.aask and BaseLLM.aask_code only
