GoKawiilAnthropic releases Claude Fable 5.2 and Mythos 5.2 models
Anthropic has launched Claude Fable 5.2 and Mythos 5.2, successors to the Fable 5.1 update released in September. The company says the new models improve on coding, reasoning, and vision tasks, run up to 30% faster than their predecessors, and cost $8 per million input tokens and $40 per million output tokens.
GoKawiil's interpretation of the reporting above, not reported fact.
Faster, cheaper top-tier models could lower the cost barrier for developers tackling complex coding and reasoning tasks, potentially accelerating adoption of Anthropic's most capable tier. Anthropic's claim that over 90% of its own codebase changes are now authored by Claude suggests the company is positioning its models as increasingly central to software engineering workflows, though this figure comes from Anthropic itself.
- Claude Fable 5.2 and Mythos 5.2 launched today as upgrades to the Fable 5.1 models from September.
- Anthropic claims up to 30% faster output generation at a reduced price of $8/$40 per million input/output tokens.
- Anthropic says over 90% of changes to its core codebase are now written by Claude with human guidance.
