LangroidInstrumental mechanismsEnabling intelligences to call external functions (e.g., APIs or code execution) is divided into two implementations:
- OpenAI function calls: Applies to OpenAI models, utilizing its native function call protocol;
- Self-developed ToolMessage: A data structure based on the inputs and outputs of the Pydantic Definition Tool for theAny LLM, including open source models.
Workflow:
- Developer-defined tools (e.g., Pydantic models for querying databases);
- LLM generates structured requests based on the conversation context to determine if the tool needs to be invoked;
- The framework executes the corresponding Python function and returns the result.
This mechanism automatically handles the LLM output of theError format JSON, improving development efficiency.
