Introducing GPT-5 for developers

OpenAI launched GPT-5 in its API for developers, positioning it as its strongest coding and agentic model.

The model claims top results on major coding and tool-use benchmarks, with better frontend work and long-running task performance.

New API controls include verbosity settings, minimal reasoning, custom plaintext tools, and three model sizes for different needs.

The release is aimed at improving code generation, debugging, tool use, and agent-style workflows for developer teams.
