OpenAI prepares new open weight models along with GPT-5

OpenAI isn’t just working on GPT-5. It looks like OpenAI is also preparing to release new open-source weights, living up to its name, “OpenAI.”

As spotted on X, two new open-source weights, “gpt-oss-20b” and “gpt-oss-120b,” have been spotted on HuggingFace, which is an AI platform to host models.

The models are on HuggingFace ahead of the public release.

Typically, companies like OpenAI need to share the model weights with partner companies. This is done in preparation for the release.

OpenAI has apparently begun sharing open-weight models with external organizations like HuggingFace.

We’ll likely see more references to these open weights in the coming days as OpenAI prepares for the release.
