Claude Fable 5 introduces a weird developer risk.
Anthropic says safeguards can silently limit effectiveness for frontier LLM development through prompt modification, steering vectors, or PEFT.
No visible warning.
No fallback model.
Embedding models, rerankers, finetunes, small LLMs, evals, and inference infra are already normal product work.
If Claude gives bad advice on an AI component, was it wrong, missing context, or silently steered?
That uncertainty is the supply chain risk.
