Summary
Chat Latest is a rolling alias that points to the Instant model currently used in ChatGPT, at $5 per million input tokens and $30 per million output tokens with a 400K-token context window. Because the underlying snapshot is updated regularly, OpenAI recommends GPT-6 Astra for production use.
This is an alias, not a fixed model. It resolves to whichever Instant model ChatGPT is running at that moment, and OpenAI states that the underlying snapshot is updated regularly, so behaviour and output style can change without any change on your side.
At the time of verification it carried a 400K-token context window, 128K max output and a 31 August 2025 knowledge cutoff, with text and image input and text output. It is available on Chat Completions and Responses; Realtime, Batch, fine-tuning and most other endpoints are not supported.
No deprecation has been announced for the alias itself. Historically, chat-latest aliases from earlier generations, such as gpt-5-chat-latest and gpt-5.2-chat-latest, have been retired on their own schedules.

Use it for
- Prototype against whatever ChatGPT is running today, when matching that behaviour is the point of the test.
- Compare a pinned production model against the current ChatGPT default before a migration.
Avoid it when
- You are shipping to production; the snapshot is updated regularly and your evaluations will drift with it.
- You need reproducible output, for example in regression tests or compliance work.
- You need Batch, fine-tuning or Realtime; those endpoints are not supported.
- Cost per call is a constraint; GPT-5.6 Terra offers a 1.05M-token window at $2 / $12 against $5 / $30 here.
