Polymarket says 80% chance of fable 5.2 release over the next 8 days, it feels pretty consistent to me with other release periods, where the existing models feel "dumbed down".

funnily livenerf is showing the model to be slightly more intelligent these days: https://github.com/ninjahawk/livenerf

Livenerf is also using a subscription to run, not API, so it's apparently not a subscription thing. Maybe if you're unlucky you're served with a quantized model until they release fable 5.2 ?

You have to assume they detect benchmarking / testing and feed those clients consistent models.
