Version of GPT-5 that produces smarter and more precise responses Version of GPT-5 that produces smarter and more precise responses GPT-5 pro uses more compute to think harder and provide consistently better answers. GPT-5 pro is available in the Responses API only
to enable support for multi-turn model interactions before responding to API
requests, and other advanced API features in the future. Since GPT-5 pro is designed
to tackle tough problems, some requests may take several minutes to finish.
To avoid timeouts, try using background mode.
As our most advanced reasoning model, GPT-5 pro defaults to (and only supports) 272,000 max output tokens Sep 30, 2024 knowledge cutoff Pricing Pricing is based on the number of tokens used, or other metrics based on the model type. For tool-specific models, like search and computer use, there’s a fee per tool call.

Below is a list of all available snapshots and aliases for GPT-5 pro . Rate limits Rate limits ensure fair and reliable access to the API by placing specific caps on requests or tokens used within a given time period. Your usage tier determines how high these limits are set and automatically increases as you send more requests and spend more on the API.![]()
