Open models by OpenAI

What it does

The gpt-oss playground is a demo platform designed for developers to explore OpenAI’s open-weight models, specifically gpt-oss-120b and gpt-oss-20b. It allows users to interact with these models and observe their reasoning capabilities.

How to use: Users can interact with the gpt-oss models by selecting either gpt-oss-120b (designed for large-scale infrastructure) or gpt-oss-20b (optimized for on-device running). They can also choose a reasoning level (High, Medium, Low) to observe the model's output. By continuing, users acknowledge that the reasoning provided is for demo purposes and may be verbose, speculative, or inaccurate.
