That doesn't make parent's claim true or even relevant.
And OpenAI could release an open model tomorrow. Nobody knows.
You forgot the GPT-2 that came long before that. OpenAI was the lab that releases open models.
None of this is factually correct, that is it. I don't think this is debatable. I don't love OpenAI, but OpenAI made huge contributions to the field, and one should give credit where credit is due.
I have great trouble understanding why someone would waste time defending it.
they've released gpt-oss-safeguard in October
I hope / think they are going to release more, just going for one big release a year like Gemma (if we talk strictly about general chat model -- Gemma 3 was March 2025)
gpt-2, CLIP, Whisper, Point-E, got-oss-120b, gpt-oss-20b.
