Claims
- Anthropic is releasing a public version of its Mythos model under the codename Fable.
- Fable is priced at approximately 2x the cost of Claude Opus.
- Earlier previews of Mythos had suggested pricing as high as 5x Opus, making Fable's pricing a relative relief.
- Fable will ship with strong safety guardrails.
Key quotes
It's costly, at 2x the price of Opus, but maybe still cheaper than what people expected after seeing the first Mythos pricing at 5x Opus.
It will come with strong safety limits.
