METR says Anthropic redacted a majority of the evidence it found most informative from the public version of a roughly 100-page report. The statement was posted by METR on X (@metr_evals) and surfaced on Techmeme on November 5, 2026.

What METR says

According to METR, it submitted a ~100-page full report on its assessment to Anthropic. For the public version, METR says, Anthropic redacted "a majority of the evidence we found most informative."

METR states the consequence directly: "the public must rely on our judgment more than we consider ideal." In the headline summary of the post, METR describes the redacted material as the "most informative" evidence, and says readers "must rely on our judgment more than we consider ideal."

Key details

  • Author of the statement: METR, via its @metr_evals account on X.
  • Length of the full report: approximately 100 pages, as stated by METR.
  • Party that redacted: Anthropic, according to METR.
  • Scope of redaction: a majority of the evidence METR considers most informative, according to METR.
  • Stated effect: readers of the public version depend more heavily on METR's own conclusions than METR considers ideal.

These details come from METR's account. Only a short feed summary of the post was available, so further specifics of the assessment are not covered here.

What this means

A public report is only as checkable as the evidence it contains. METR says the redactions removed most of the evidence it considers most informative, so outside readers have less underlying material to test its conclusions against. METR itself frames this as a departure from the ideal: its judgment, rather than the full evidence, carries more of the weight in the public version. Readers evaluating the report should treat its conclusions as METR's assessment, and should note that METR says the fuller evidence behind them exists in a ~100-page version that was submitted to Anthropic.
