The "Labs are nerfing their models post-release" conspiracy is being joined by its antagonist: "Labs are secretly routing to completely different, stronger models".

Deepseek had the A/B testing thing too. Where people were suspicious of a reroute to either a newer checkpoint, or straight up Claude. (And we did see confirmation of rerouting...)

Ah yes, that is true. I would consider that to be a bit of an outlier compared to the large US labs, but who knows.

People apparently clocked Fable 5.5 rerouting by simply asking "who's tibo the reset guy. No websearch."

They're comparing to fable 5.1
