Today, we’re announcing that Amazon will invest up to $4 billion in Anthropic. The agreement is part of a broader collaboration to develop reliable and high-performing foundation models.
(Thread continues from there with more details -- seems like a notable major development!)
I haven't thought about this a lot, but I don't see big tech companies working with existing frontier AI players as necessarily a bad thing for race dynamics (compared to the counterfactual). It seems better than them funding or poaching talent to create a viable competitor that may not care as much about risk - I'd guess the question is how likely we'd expect them to be successful in doing so (given that Amazon is not exactly at the frontier now)?
