Anthropic's Claude Fable 5.2 Arrives Faster and Cheaper for Serious Coding and Research Work
By Google News AI ·
Anthropic released Claude Fable 5.2 today, the most recent version of its model designed for rigorous technical tasks. Regular users benefit from faster responses, clearer writing, and a price reduction that reduces the cost down to $8 per million input tokens and $40 per million output tokens.
An optional fast mode doubles those rates in exchange for generating speeds that are two and a half times faster than the usual setting.
Compared to the previous version, everyday outputs now arrive up to 30% faster, yet the model still processes text and pictures, including PDFs, inside a one-million-token context window that allows for long sessions without constant restarting. Coding tasks are where the major gains are seen. Engineers evaluating the model completed things that previous versions could never even try in a reasonable time frame.
They completed a production service migration from Python to Rust, which is now around 26 times faster. It has also enabled big numbers of sub-agents to collaborate on multi-repo projects while assessing and revising their own work.
