Anonymous Repository Claims to Have Leaked Anthropic Model, Authenticity in Doubt
An anonymous Hugging Face account has released a repository claiming to hold an intermediate pre-training checkpoint for Anthropic's internal model, Numbat. The model reportedly has ~14 trillion parameters, with weight files totaling ~7.72 TB. Numbat previously surfaced in leaked Claude Code source code from March 2026. However, the uploader has provided no proof of origin, and the model weights remain independently unverified, leaving the community skeptical about its authenticity.
