I stopped using Fable long time ago. It's worse than Sonnet. Opus is not much better.
This cycle of new model running at full quantisation and then nerfed few days / weeks after premiere should be called out. Anthropic should also drop the adaptive reasoning scam.
If I pay for Fable, I should get full, not nerfed model at honest pricing.
Regulators should investigate them.
OpenAI is no different. Astra has basically the same problem.
