Just imagine Anthropic making Opus open-weights now for the sake of trolling everyone. Wouldn't surprise me at this point xD
That OpenAI releases Sol as downloadable weights feels way more likely than Anthropic releasing even the tiniest of models for download.
That would go against everything that Dario believes in (note that I refer to the CEO and not the company; the staff at Anthropic are not so ridiculous). He believes in Anthropic being the sole arbiter of the forefront of this technology, because it is all too dangerous in the hands of anyone else.
