Claude Fable 5.2 retakes World #1 LLM spot as Anthropic IPO roadshow begins
2 reports
Anthropic shipped Claude Fable 5.2 and Mythos 5.2, retaking the top LLM spot from Gemini 4 Carbon. Fable 5.2 cuts token prices 20% to $8/$40 per million, but is more token-hungry, lifting GDPx task cost from $67.16 to $88.15. It leads independent leaderboards at 16.4% and matches Opus 5.5 at Max on FrontierCode 2.0 for about half the cost per task at High effort.
Why: New top model changes pricing and cost-per-task math for production AI users.

Claude Fable 5.2 and Mythos 5.2 cement Anthropic's AI lead just before its IPO
Anthropic released Claude Fable 5.2 and Mythos 5.2, its most powerful models to date, in free and verified-organization versions. According to the company, the models solve open physics problems, show stronger cybersecurity capabilities, design functioning operating systems, and write more than 90 percent of changes merged into Anthropic's core code. Anthropic says it deliberately curbed any capabilities that would let the AI accelerate its own development.
Why: Major Anthropic model release with free tier and bold capability claims ahead of IPO.
