OpenAI just announced something big, but it's not GPT-5

• OpenAI has released gpt-oss-20b and gpt-oss-120b as open-weight models
• The gpt-oss-20b model can run locally on a consumer PC
• These models let users see each step of the AI's thinking process, making them more transparent in how they function

OpenAI has just dropped two new AI models, gpt‑oss‑120b and gpt‑oss‑20b. Not only are they new, but they're the first open‑weight models from ChatGPT's creator since GPT‑2.

The smaller of the two – gpt-oss-20b – is especially notable for being light enough to run on a decently specced consumer PC. If you’ve got about 16GB of RAM and some patience, you can load it up, ask it questions, and actually see how it arrives at answers. The larger 120b model still requires serious hardware or cloud support.

Both models are part of OpenAI's new push to encourage developers ...
