Anthropic (all ex Open AI) knew the negatives of the deal, so they made a slightly better deal with AWS, not a full lock in. They also grounded it in hardware from the start, ie. being the flagship customer for Trainium, the flagship customer for external usage of TPU's.
Domain knowledge, expertise, is a big thing in tech, because code can be written fast if you know what to do, and so by having that expertise, building a frontier model is a matter of time and capex. Anthropic is founded by top ex-openAi, so they are not lacking in expertise, and are not attached to SamAlt. It’s an easy choice of who to finance.
Anthropic will win long term because big tech knows how much of a loud mouth sam is, how much of the piee he wants, he is more of a rival then some company they could use to grow. While Anthropic (even though they aren’t really good guys) seems more like a shared common good for the big tech then openAi, like linux corporate business deals version.
If anything you ought to expect them to be behind, since they took the position of making all the mistakes first so others (who already had the same or better tech) didn’t have to.
I think that’s underselling their contribution, which I believe is mainly: it’s possible and this is what it looks like as a product. Until that time, nobody had figured out how to shape it as a product, and ChatGPT showed how to do that. Don’t forget that for a year or two they kept making headlines all the time with Dall.E and whatnot.
For me it seems like what happened after that is where the lack of focus started to hurt them: they realized that models themselves will be a commodity and have no moat, and that they needed to somehow build a network or something to keep pulling people back in. Sora was one such attempt, and it failed hard.
To me, enterprise / B2B seems like a much easier, obvious market to approach, but I don’t know a lot about B2C. But it seems like B2C was what OpenAI was going after.
OpenAI was Anthropic. Anyone involved in actually developing GPT jumped ship when Altman performed his coup.
