Pundit ClaimsAI claims by Gary Marcus and Ed Zitron, with the evidence

“Oh, one other thing: sources also confirm GPU utilization for Microsoft 365’s enterprise Copilot is barely scratching 60%.”

The Case Against Generative AI, paragraph 285.

Our reading:

GPU utilization for Microsoft 365 enterprise Copilot is barely 60%.

Assessment: Unresolved

What happened

Was it true for the period described?

Outcome: Unresolved

We checked, and the evidence so far doesn’t settle it.

Judged on a plain reading. They named no measure, so we used the reading a typical informed reader would take. It is spelled out under “How we judged it”.

Evidence up to . Checked .

Why

The 60% figure comes from anonymous sources cited by the speaker. The packet contains no evidence items. The searches found no Microsoft figure for GPU utilization for Microsoft 365 enterprise Copilot. One report found only repeats the speaker's newsletter, so it is not independent. One site claimed utilization above 70%, but its details could not be verified, so it was not used. A third report was about GPUs not installed for lack of power, not about Copilot utilization. No usable evidence supports or contradicts the figure for August to September 2025, so the claim stays unresolved.

Caveats

  • The search found no Copilot-specific GPU utilization figure from Microsoft.
  • The search covered two queries and three sources.
  • The claim does not define utilization (average, peak or compute share).

None given. We don’t add one.

Where we had to interpret

  • Plain reading: GPU capacity serving Microsoft 365 enterprise Copilot was used at about 60%, not much above it, around the time of the post.
  • He names no period. I take the most recent period before the post, roughly August to September 2025, since the nearby text cites August figures. I do not limit it to August alone.

Right if: A Microsoft disclosure or independent reporting showing utilization of GPUs serving Microsoft 365 enterprise Copilot at roughly 60% (for example about 55–65%) around August–September 2025.

Wrong if: A Microsoft disclosure or independent reporting showing that utilization for that period was clearly different, for example well above 70%.

We wrote this test after the outcome was known.

What would settle it

A Microsoft disclosure or credible independent report, not derived from the speaker, giving GPU utilization for Microsoft 365 enterprise Copilot inference for about August to September 2025.
