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.

OpenAI unveiled its new flagship AI model, GPT-5, on Thursday. And with the launch, OpenAI seems to be moving more towards offering an entire AI system to its customers versus giving them the choice between models.

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.
