#S2.02 Fable Ban - Now What?
Notes de l’épisode
The Fable 5 incident turned an abstract AI risk into something much more concrete: frontier-model access can disappear quickly, and global teams cannot treat hosted AI infrastructure as politically or operationally neutral. Sebastian and Andre unpack the reported export-control shock, the confusing jailbreak explanation, and the immediate consequence for companies that depend on a small number of US-based model providers.
Their conclusion is deliberately pragmatic. Engineering teams should not reject frontier models just because access risk exists. The performance advantage is still too valuable. But mature teams should opt for model-agnostic harnesses, reusable workflows, fallback providers, and clear risk classification for AI-dependent systems. The model may be the visible layer, but the durable engineering capability is the surrounding system.
For CTOs and engineering leaders, the actionable question is not "Should we use Fable 5?" It is: "Which workflows break if one vendor disappears, and have we ever tested the fallback?" Internal experiments, coding assistants, customer-facing AI features, RAG systems, local models, and open-weight providers all need different resilience standards.
