I have no hard data but I have a strong feeling this morning that something's wrong with Fable 5 compared to Friday evening.
Just an hour ago I had Fable correctly identify an unused method that could be deleted. I then immediately get a diff for an exact duplicate method, and then Fable outputting, "I accidentally duplicated <method> instead of deleting it. Removing both copies now."
The remaining morning complaints that makes it feel like something's off is that it will do a lot of "thinking" for simple things that previously took very little time. And it got very lost and completely mixed up DE-91M predicate names and implementations. Just absolute disaster code that I had over the past months come to generally expect it to do without issue.
Glad I carefully review everything. I think what I need is reliability and consistency. But it feels like picking a model from the list doesn't guarantee that: that the models' "brain" is open on the table and they're screwing with it.
Can you elaborate on the mechanism of this degradation? If resources are not available I would expect a request to fail with a message about resources not available. Do they tweak back end model capabilities to maintain service in a degraded state?
An AI lab will never volunteer the information because it opens them up to lawsuits if they are purposely degrading service and not letting users know.
They can limit how hard the model thinks for a given effort. Suddenly xhigh only thinks as hard as high did, and high shifts down to medium effort, and so on.
They can also serve quantized models. And this has the benefit of practically not showing up in benchmarks at all even if the user experience is obviously degraded.
The other major thing the labs do is silently drop the usage limits. This has become very noticeable for codex users who are suddenly burning through their weekly usage in a few hours.
Yea, if you ever run your own models on a GPU there are a whole ton of different dials you can adjust that drastically affect compute use, memory use, and output token quality, and number of tokens held in memory.
If anyone reading has a GPU it's worthwhile just messing with a smaller model for a bit to watch how the settings affect output.

Opus 5.5 is being served under opus 5 right now.
