Overview
GPT-5 is OpenAI’s most intelligent model yet, and it brings major gains across reasoning, reliability, and specialized use cases.
- Dynamic reasoning (“think hard about this”) enables expert-level responses on complex tasks
- Much better at complex front-end generation
- Best model yet for health-related questions
- Significant reductions in hallucinations (~80% less with thinking mode vs. o3)
It supports a 400,000 token context window and up to 128,000 output tokens
Earlier iterations of this model were available as Horizon Alpha and Horizon Beta
