# Enum ResponseFormat

All Implemented Interfaces:
  `Comparable<ResponseFormat>`

public enum ResponseFormat extends Enum<ResponseFormat>
Constrains the model's output format. `TEXT` is the default; `JSON_OBJECT` forces the model to emit valid JSON (OpenAI/Gemini honour this directly; Anthropic emulates via a system-prompt guardrail in the client).
