Details
OpenAI unveiled GPT-5.5, describing it as a model that thinks faster and more precisely than the previous 5.4, using fewer tokens.
Greg Brockman positioned it as the next step toward agentic computing and intuitive computing, and again mentioned the superapp concept combining ChatGPT, Codex, and an AI browser. The pace of releases has also accelerated, with this new model following last month's GPT-5.4.
The key use cases are as follows.
- agentic coding and knowledge work
- mathematics and scientific research
- cyber defense and drug discovery
OpenAI claimed benchmark performance higher than competing models from Google and Anthropic. Rollout has begun for Plus, Pro, Business, Enterprise users, and 5.5 Pro is available to Pro, Business, and Enterprise.
