Anonymous X account claims OpenAI crushed Anthropic's offering, offers zero proof tweet on X

An account called Chubby posted the same tweet three times in a row on X. OpenAI "crushed Anthropic's offering," it says. The new Fable 5.1 model, described as "state-of-the-art," is put to ridicule. "Just look at the numbers. Its not even close." No numbers appear. No benchmark. No source. Just the line, repeated.

Repetition as tactic

Triple-posting the identical claim looks like an attempt to cement a narrative through volume instead of evidence. No link to a report, no official statement, no comparison data. Only the insistence that the numbers speak for themselves — while the numbers themselves are nowhere to be found.

A reply that raises eyebrows

Another user noticed the shift. An hour earlier the account was enthusiastic. Now it cannot get access to verify anything itself but keeps pushing the claim. The reply asks directly whether this is paid promotion and why the lack of access does not frustrate the poster.

No outside confirmation

As of publication, nothing official from OpenAI, Anthropic, or any regulator confirms an imminent Anthropic offering, the existence of Fable 5.1, or any performance comparison between the two. The tweet remains a single, unsourced claim from an account with no identifiable journalistic or institutional affiliation.
