That is true. But it is not the same model as the LLM created by combining the released weights with the released architecture. The thing that is the "binary blob" is the weights. It is pretty much exactly akin to a Linux driver that depends on linux-firmware. It is wonderful that it exists! But it is only partly open.

| Now, what licensing does, and the only thing that licensing can do is to give you rights to inspect, modify and release that model. That's it. A license will never give you (it cannot) the right to have the internal IP, knowledge, know-how or the "why's" on how the model was edited. That's on you. You have the right to modify, but you can't get the right to know how others have modified it, from a license file. Never had, never will.

| In practice, we do have fully open (open data, open training code, open source models) models. Apertus, from Switzerland and Olmo from the US. Don't get me wrong, it's absolutely great that we have these models, they are very important for the community, and they do help inform everyone about what works, what doesn't, and so on.

You seem to contradict yourself here. That said: I appreciate the correction of my perception that there aren't truly open large language models.

Closed weight models are the equivalent of SaaS. Open weight models are the equivalent of binary driver blobs or Windows software. We don't really have actual open source LLMs, which would need to publicly release their training data and technique so you could train a similar model yourself, or use their work as a baseline for your own model.

This distinction matters because an actual open source LLM would be extremely important from an ecosystem point of view, if someone ever actually released one.

Best they can do is to somewhat reliably react to objective signals that they've failed at something (like test failures).

Not because they use CSV's but because, as an industry, they have not figured out how to reliably create, exchange, and parse well-formed CSV's.

As Paul Graham said, "Sam gets what he wants" and "He’s good at convincing people of things. He’s good at getting people to do what he wants." and "So if the only way Sam could succeed in life was by [something] succeeding, then [that thing] would succeed"

What it does is prevent companies that Anthropic needs to do business with from doing business with Anthropic.

As long as the consequences of his actions continue to increase the paper value for investors, regulations don't really have teeth because there aren't damages. So the snowball gets bigger and the process repeats.
