About this model
gpt-oss-20b is the smaller of OpenAI's two open-weight reasoning models, released in August 2025 under the Apache 2.0 license. It is a text-only Mixture-of-Experts model with 20.9B total parameters, 3.6B active per token, and a 131,072-token context, and OpenAI positions it for lower latency and local or specialized use cases. Like gpt-oss-120b, it offers low, medium and high reasoning effort, with native function calling and Structured Outputs. At high effort, OpenAI reports 91.7% on AIME 2025 without tools and 60.7% on SWE-bench Verified, close to the 120b's 92.5% and 62.4%, while the larger model leads on GPQA Diamond, 80.1% versus 71.5%.
