OpenAI gpt-5-pro
Version: 2025-10-06
Direct from Azure models
Direct from Azure models are a select portfolio curated for their market-differentiated capabilities:- Secure and managed by Microsoft: Purchase and manage models directly through Azure with a single license, consistent support, and no third-party dependencies, backed by Azure's enterprise-grade infrastructure.
- Streamlined operations: Benefit from unified billing, governance, and seamless PTU portability across models hosted on Azure - all part of Microsoft Foundry.
- Future-ready flexibility: Access the latest models as they become available, and easily test, deploy, or switch between them within Microsoft Foundry; reducing integration effort.
- Cost control and optimization: Scale on demand with pay-as-you-go flexibility or reserve PTUs for predictable performance and savings.
Key capabilities
About this model
gpt-5-pro uses more compute to think harder and provide consistently better answers.Key model 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.

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 .
