According to @AnthropicAI, the Anthropic Fellows Program introduced Selective GradienT Masking (SGTM), a training method that isolates high-risk knowledge into a small, separate set of parameters that can be removed without broadly affecting the model.

No information is disclosed about partnerships, revenue impact, token integrations, or compute procurement that would directly influence crypto markets or AI-linked equities.

For traders, confirmed data points are the method name (SGTM), purpose (containing high-risk capabilities), and the claim that removal minimally impacts overall model behavior, while the announcement remains informational without market-moving disclosures.
