OpenAI’s new open-weight models are gpt-oss-120b and gpt-oss-20b. The smaller model, gpt-oss-20b, can be run on a consumer laptop or powerful phone.

For the first time in more than five years, OpenAI is launching a new open language model that appears to be state of the art.

Developers rejoice—OpenAI has just released two new open-weight models. Unlike most of OpenAI’s models, these new products can be downloaded and used without needing to pay API fees to OpenAI. The models can even run locally on laptops and phones.
