Where is chat-latest a perfect fit?
chat-latest is OpenAI’s API alias for the latest Instant model used in ChatGPT. Unlike a fixed snapshot, its underlying model is regularly updated, so OpenAI recommends GPT-5.6 instead when production applications require greater model stability.
- Testing the current ChatGPT Instant experience through the API
- Conversational assistants prioritising fast, natural interactions
- Applications that benefit automatically as the underlying ChatGPT model changes
- General text generation, summarisation, extraction, and classification
- Image-understanding applications requiring text responses
- Function-calling and structured-output workflows
- Applications using web search, file search, code interpreter, image generation, or MCP
- Experimentation where staying aligned with ChatGPT matters more than pinning model behaviour
