Single-source incident — one report is available.

Why it matters

The numbat repository warrants provenance scrutiny as a purported proprietary-model disclosure, but defenders should not treat its claims as confirmation of an Anthropic breach.

The Hugging Face repository burner22/numbat claims to distribute an unreleased Anthropic model checkpoint, including reference Python code and approximately 7.72 TB of weight shards. The supplied model card does not independently substantiate the checkpoint’s attribution or establish that an Anthropic compromise occurred.
