Start building with GPT-5
GPT‑5 is OpenAI’s most advanced model to date, with meaningful improvements in reasoning, reliability, and adaptability, and standout capabilities for coding and builder workflows. Whether you’re refactoring a large codebase, integrating AI into your app, or orchestrating multi‑tool workflows, GPT‑5 provides advanced coding assistance and precise tool use.
Why it matters for builders
- Coding performance: Strong results on benchmarks such as SWE‑bench Verified.
- Tool integration: Supports free‑form function calling, structured outputs, and tool‑call preambles for smoother workflows.
- Flexible reasoning modes: Use minimal reasoning for speed and deeper reasoning when tasks require more analysis.
- Large context window: Work across bigger inputs and longer interactions.
