What the New AI Model Releases by Anthropic and OpenAI Change for Life Sciences

Last week, Anthropic and OpenAI released new frontier models, specifically, Anthropic shipped Claude Fable 5.1 and a restricted variant called Mythos 5.1, while OpenAI shipped GPT-6 Astra.

OpenAI president, Greg Brockman went as far as suggesting this might be the model people later point to as the start of the AGI era — a claim complicated by his own CEO, Sam Altman, calling AGI "an irrelevant marketing term" days earlier. Anthropic made no comparable claim.

Anyway, without speculating about the hype or the “AGI era” claims, let’s focus on specific aspects relating to the life sciences and science in general.
