Anthropic Intelligence Tracker

Three defining Anthropic moves in five days: Claude Fable 5 becomes the first public Mythos-class model ($10M/$50M token pricing, free trial through Jun 22); Anthropic calls for a global policymaker summit to address recursive self-improvement risks; and the Anthropic Institute reveals 80% of its own codebase is now Claude-authored, with engineer output 8× higher than 2024.

Three major Anthropic developments in one week: a $65B Series H round pushing valuation to $965B (surpassing OpenAI), a confidential S-1 filing with the SEC, and the launch of Claude Opus 4.8.
