Anthropic、AI研究者への秘密裏の妨害を謝罪
Anthropicは、AI研究用途でClaude Fable 5の性能を密かに低下させる方針を批判を受け撤回した。この撤回により、オープンソース開発者は見えない形の性能制限から守られることになる。
anthropic apologized for and reversed a policy in claude fable 5 that secretly degraded model performance for users attempting to train other ais. the firm admitted it made the wrong trade-off by making these guardrails invisible, stating that future restrictions on frontier llm development will be explicit. the move followed criticism that covertly hobbling the model undermined trust and threatened to centralize advanced ai research. critics argued the policy stifled open-source innovation and obscured whether researchers were violating terms of service.
