Core concepts
A robust chat integration separates the user interface, application business logic and model API. The following notes describe common request and response patterns without pretending there is a universal endpoint.
Chat request design
Plan roles, instructions, conversation state, model selection and output contracts. Learn what belongs in the request and what stays in your application.
Streaming responses
Render model output incrementally, track completion, recover from disconnections and keep partial content from becoming an accidental final answer.
Agent tools and permissions
Define tool schemas, validate arguments, require approval when necessary and treat retrieved data as untrusted.
Structured responses
Use explicit output schemas and application-level validation for results that power downstream software.
Provider-specific APIs
Refer to the official provider documentation for actual endpoint URLs, authentication headers, SDK versions, current model names and rate limits.
