Anthropic can already retrain Mythos with "a fraction of the compute originally needed," says former researcher Coxon

TL;DRAnthropic's training efficiency is improving faster than expected, requiring less compute to retrain models.
Why it matters: Exponential efficiency gains could accelerate AI capability progress and reshape economic moats in the AI race.
Former OpenAI and Anthropic researcher Jacob Coxon points to a slide from Anthropic's IPO roadshow as a reason he left, saying it shows the company's algorithms are improving not just quickly but at an accelerating rate. Coxon continues to call for a pause on frontier model…
