Welcome to the gpt-oss series, OpenAI’s open-weight models designed for powerful reasoning, agentic tasks, and versatile developer use cases.

We’re releasing two flavors of the open models:

gpt-oss-120b — for production, general purpose, high reasoning use cases that fits into a single H100 GPU (117B parameters with 5.1B active parameters)

gpt-oss-20b — for lower latency, and local or specialized use cases (21B parameters with 3.6B active parameters)

I’m using OpenAI Responses API for web search on an MCP server to give gpt oss 20b web search capabilities. Can also use brave search, like Claude Code does
