The gap in communication is we don't mean _literally_ no one _ever_ open-sourced models. I agree, that would be absurd. [1]

Companies, quite infamously and well-understood, _did_ hold back their "real" generative models, even from being available for pay.

Take a stab at a literal definition: - post-GPT2 LLMs (ex. PALM, PALM2) - art like DaLL-E, Imagen, Parti

Loosely, we had Disco Diffusion for art, and GPT-3 for LLMs, and then Dall-E, then Midjourney. That was over an _entire year_, and the floodgates on private ones didn't open till post SD/ChatGPT.

[1] thank you for the lengths you went to highlight the best over a considered span of time, I would have just said something snarky :)

[2] I did not realize FLAN was open-sourced a month before ChatGPT, that's fascinating: we're stretching a bit, beyond that, IMHO: the BERTs aren't recognizable as LLMs.
