Anthropic has updated its most powerful models and released Claude Fable 5.2 and Mythos 5.2.
Fable is available to everyone and has safeguards against misuse in cybersecurity and biology.
Mythos goes only to vetted organizations through special verification programs.
The new models generate answers up to 30% faster than 5.1 and cost less: $8 per million input tokens and $40 per million output tokens. An optional fast mode speeds generation up by as much as 2.5x.
