Chat completion

An API-driven architecture that processes conversational history to generate contextually aware text responses.

Chat completion transforms structured arrays of user and system messages into coherent, high-probability text outputs. Using models like GPT-4o, the system manages state through multi-turn message objects (role: user, role: assistant) rather than raw text blobs. Developers leverage specific parameters like temperature for creative variance and top_p for nucleus sampling to control output determinism. This technology powers diverse applications from automated customer support bots to complex code generation tools by predicting the next token in a sequence based on the provided conversational context.
