OpenAI gpt-5-pro
Version: 2025-10-06
gpt-5-pro uses more compute to think harder and provide consistently better answers.
gpt-5-mini : A lightweight version for cost-sensitive applications.
gpt-5-nano : Optimized for speed, ideal for applications requiring low latency.
gpt-5-chat : Advanced, natural, multimodal, and context-aware conversations for enterprise applications.
gpt-5-pro : Produces smarter and more precise responses; designed to tackle tough problems.
Key Capabilities
- Designed for logic-heavy and multi-step tasks.
- Since gpt-5-pro is designed to tackle tough problems, some requests may take several minutes to finish.
- As OpenAI's most advanced reasoning model, gpt-5-pro defaults to (and only supports)
reasoning.effort: high. - New "allowed tools" tool choice that enables you to specify multiple tools in the tool choice instead of just one.
- New "preamble" support, allowing the model to "think" before calling a tool. This is always enabled and controlled through prompting.
- gpt-5-pro does not support code interpreter.

Safety
OpenAI has incorporated additional safety measures including new techniques to help the models refuse unsafe requests. These advancements make the o1 series some of the most robust models available. OpenAI measures safety by testing how well models continue to follow its safety rules if a user tries to bypass them (known as "jailbreaking"). In OpenAI’s internal tests, GPT-4o scored 22 (on a scale of 0-100) while o1-preview model scored 84. You can read more about this in OpenAI’s system card and research post .Model Specifications
