Alleged 8TB "Claude Fable 5" weights leak via misconfigured AWS S3 bucket, unverified
speedb0at · reddit · 2026-10-31
Per an unverified Dark Web Informer post: an actor using the handle "localizer" claims to have obtained a 7GB shard of Anthropic's unreleased "Claude Fable 5" model weights from a misconfigured AWS S3 bucket associated with Amazon Bedrock.
Key points:
- The actor claims the full model is 640 shards totaling 8TB, but says only one shard was retrieved before access was restricted
- Screenshots of a .safetensors file, model metadata, and a hex dump were published as alleged proof, and the material is now being offered for sale
- The claim remains unverified; the files' authenticity and connection to Anthropic have not been established
The thread asks when a GGUF of Fable 5 will appear, with the community already musing about running it locally if the weights are real.
