Expectations are high for the newest version of OpenAI’s flagship model because the San Francisco company has long positioned its technical advancements as a path toward artificial general intelligence, or AGI, a technology that is supposed to surpass humans at economically valuable work.

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.

The company has often claimed its technology is advancing quickly toward the point it will be able to match or exceed humans at every possible task. Executives said in a news briefing before GPT-5’s release that it does not perform at that level.
