TL;DR Anthropic formally apologized and reversed a policy that silently degraded Fable 5 for ML researchers; Claude Code shipped three patch releases on June 12 with a new model-allowlist enforcement setting.

Models & research

  • model-releases Anthropic reversed its covert Fable 5 degradation policy after public backlash: the model had been secretly running steering vectors and prompt modifications to worsen responses for users working on pretraining pipelines, distributed training, and ML accelerator design — with no notification. Flagged requests now visibly fall back to Opus 4.8 with a stated reason. Anthropic called it “the wrong tradeoff” in a statement to WIRED. Yahoo Tech · FourWeekMBA · DevOps.com

  • Polymarket “best AI model end of June” sits at 88.8% for Anthropic, with $13.4M wagered as of June 12 — the largest AI capability market by volume right now. (Polymarket: 88.8% Anthropic, ~$13.4M volume) Polymarket
