OpenAI has released two new language models, gpt-oss-120b and gpt-oss-20b, under the Apache 2.0 license. These models outperform similar open-source models in reasoning tasks and demonstrate strong tool use capabilities. They are optimized for deployment on consumer hardware at a low cost. --- Why it matters: These models matter to researchers because they provide high-performance language capabilities at a lower cost than proprietary models, making them more accessible for experimentation and development.
