OpenAI unveiled 10 frontier math results from its unreleased Astra model: 24 hours later, an Anthropic researcher says the already-available Claude Fable reproduced five of them.
According to Levent Alpöge, Fable worked autonomously with a generic prompt, no internet access and safeguards against the OpenAI solutions leaking into context.
Only one of the five used essentially the same argument. The other four may be independent proofs.
It seems that OpenAI is now reaping the first-mover success with scientific breakthroughs in new models.
