What was claimed

AN ALLEGED MYTHOS-CLASS MODEL WITH 14 TRILLION PARAMETERS JUST APPEARED ON HUGGING FACE... 14 TRILLION PARAMETERS, 1,224 MoE EXPERTS, 7.72 TB OF WEIGHTS

Our verdict

Needs caution

Multiple independent audits proved the weights are fake. 43 complete tensors can be regenerated bit-for-bit from their names using seeded random number generators. Trained weights cannot be produced this way. No independent confirmation from Anthropic or Hugging Face establishes the weights' provenance. Analyses reported that sampled weights appeared synthetic or fabricated.

Assessment summary

  • The repository and its claimed specifications appear to exist, but the claims that it is a genuine Anthropic Mythos checkpoint and contains real trained weights are unverified.
  • Available analyses instead report synthetic or fabricated-looking weights, so the statement is misleading if presented as a confirmed leak.x.com tokenpost.com maccus.fr

Claims reviewed

The repository is a genuine Anthropic Mythos-class model or verified leak.

Can’t verify
No independent confirmation from Anthropic or Hugging Face establishes the weights' provenance. Analyses reported that sampled weights appeared synthetic or fabricated.x.com tokenpost.com maccus.fr

A model repository claiming to be a Mythos-class model appeared on Hugging Face.

Supported
Reports identify the Hugging Face repository burner22/numbat, created in October 2026, which claimed to contain an Anthropic Mythos-class checkpoint.tokenpost.com maccus.fr

The repository claims approximately 14 trillion parameters.

Supported
The repository description reportedly lists about 14 trillion parameters.tokenpost.com maccus.fr

Assessment summary

  • The statement accurately describes what appeared on Hugging Face (a repository claiming 14T parameters, 1,224 MoE experts, and 7.72 TB of weights), but it presents this as a straightforward fact without critical context.
  • Multiple independent analyses have proven the weights are synthetically generated, not trained—43 tensors can be regenerated exactly from their names using seeded random number generators.
  • The statement is technically accurate but dangerously misleading by omitting that the "leak" is fabricated.

An alleged Mythos-class model with 14 trillion parameters appeared on Hugging Face

Supported
A repository (burner22/numbat) did appear on Hugging Face claiming these specifications. However, the word 'alleged' is crucial—the claim itself is unverified and has been proven false.

The model has 1,224 MoE experts

Supported
The repository's model card claims 1,224 Mixture-of-Experts experts. This is what the repository states, though the underlying weights are fabricated.

Assessment summary

  • A Hugging Face repository claiming an Anthropic "Mythos-class" checkpoint with ~14 trillion parameters did appear and circulated widely online sawongam.com aib.vote.
  • Independent analysis and Hugging Face's own parameter scan however show the files contain ~6.8T parameters and multiple researchers flagged the weights as likely synthetic, contradictory to the uploader's 14T/1,224-expert/7.72 TB claim ailately.com fourweekmba.com.

Claims reviewed

The files actually contain 14 trillion parameters and genuine Mythos-class weights.

Contradicted
Hugging Face's scan reports ~6.85T parameters in the uploaded files and multiple investigators found statistical signs the tensors are synthetic, not genuine Mythos-class weights ailately.com fourweekmba.com.

This claim may mislead readers without added context.

An alleged Mythos-class model with 14 trillion parameters, 1,224 MoE experts, and 7.72 TB of weights just appeared on Hugging Face.

Needs context
A Hugging Face repo did appear making those exact claims, so the posting itself is real sawongam.com aib.vote. But Hugging Face's automated parameter count shows ~6.8T parameters and independent analysts reported many tensors look synthetic, so the uploader's specific numbers are contradicted by evidence ailately.com fourweekmba.com.

This claim may mislead readers without added context.
