Function Calling
Function calling is a standardized protocol through which an LLM generates structured function calls instead of free text. The model recognizes which function is needed and delivers parameters in the correct JSON format. IJONIS uses function calling as a building block for reliable AI agents in production environments.
Why does this matter?
Function calling makes AI agents reliable enough for production use. Instead of parsing unstructured text responses, your systems receive exact, machine-readable calls. This eliminates parsing errors and enables safe AI integration into business-critical workflows like procurement, invoice verification, or CRM maintenance.
How IJONIS uses this
We implement function calling via the OpenAI standard with LangChain abstractions and Pydantic validation. Every function receives a typed schema, automatic parameter checking, and retry logic — so your agents work stably even with unexpected inputs.
