AWS Bedrock

The complaint names a specific method: training a weaker model on a stronger one's outputs, the technique Anthropic calls "distillation." The thread's twist is that almost nobody buys the framing as a copyright grievance.

A self-described insider says the labs distill via AWS Bedrock, not Anthropic's restricted platform, so the company may not even hold the evidence. A UK student lays out the real pipe: Chinese resellers hawking Opus tokens at a 93% discount and selling the reasoning traces as training data.

The carve-outs — 30-day retention, exceptions for safety investigations and legal requirements — read as reasonable in isolation, until you remember teams send proprietary code and customer data through these systems.

Two EU practitioners flatly disagreed in the same thread: 'This is not going to fly in EU' versus 'Yes it will — clear purpose, customer agrees.'
