About gpt-oss-120b
gpt-oss-120b was OpenAI’s first open-weight language model since GPT-2, released in August 2025 under Apache 2.0. OpenAI says it comes close to o4-mini on core reasoning tests and beats it on competition maths and health questions, and it scores 80.1% on GPQA Diamond. It was built to fit on a single 80GB GPU.
It reasons at low, medium or high effort and shows its full chain of thought. Its small active size makes it inexpensive to run, which makes it a sensible choice for maths, logic and structured tasks at volume.
What is gpt-oss-120b good for?
- Maths, science and logic problems.
- Structured, step-by-step tasks at volume.
- Agent steps that call functions.
Where to be careful
- Its knowledge stops at June 2024, the oldest of the reasoning models here.
- Text only.
