Anthropic slashes Claude Fable 5.1 and Mythos 5.1 prices by ~25% to defend enterprise share
Anthropic has cut pricing for its new Claude Fable 5.1 and Mythos 5.1 models by roughly 25% on standard workloads, framing the move as a response to OpenAI's GPT-6 Astra launch and the rise of cheaper open-weight alternatives. The new pricing arrived alongside Claude Fable 5.1's release on September 1 and OpenAI's response launch on September 2, intensifying a frontier-AI price war that has now produced three major enterprise tier resets in 30 days.
