- Uses the (now-lifted) US ban on Claude Fable 5/Mythos 5 for foreign nationals as a case study in vendor-dependency risk: while everyone watched Fable 5, open-weight models (GLM 5.2, GPT-OSS) closed most of the capability gap and now match flagship benchmarks on much everyday work, at roughly a tenth of the price.
- Practical takeaway: diversify model dependency before a single-vendor outage or regulatory action forces the issue — open-weight substitutes are now credible enough to be a real fallback, not a theoretical one.
