At a glance
- Validate vendor claims against your own tasks.
- Check specialist permissions and account configuration separately.
A shared model with distinct access
Anthropic says Fable and Mythos share an underlying model, with different safeguards and verification arrangements. Performance claims in the launch announcement are vendor evaluations.
Announced standard rates are $8 per million input tokens and $40 per million output tokens. Fast mode is priced separately.
Check the verification program
The Cyber Verification Program defines tiers with different eligible applicants, accounts and permissions. Approval and assigning access to a workspace are separate steps.
Its documentation says everyday secure development can begin with generally available models, including code review and fixes for known issues.
88Z perspective: budget by task
Separate difficult architecture decisions and debugging from routine formatting work. Give each category a clear acceptance test and budget before comparing models.
For specialist tasks, confirm the account’s actual permissions. A model appearing in a catalogue does not establish that the account can perform every supported use case.
