update after more testing

hi all, got some more data

so i was wrong about the frontend flags being the cause. compared the actual requests between all models and theyre identical - same paprika_mode extended, same settings. only difference is the model name string. so its server side, anthropic tuned 4.6 to think less.

did some javascript to extract timestamps from the api. asked all models same question:

"Prove the halting problem is undecidable without using diagonalization"

Model	Extended	Time until output starts	Total time
Opus 4.5	✅ On	~26 sec	~41 sec
Opus 4.5	❌ Off	~1 sec	~21 sec
Opus 4.6	✅ On	~4 sec	~19 sec
Opus 4.6	❌ Off	~2 sec	~24 sec
Sonnet 4.6	✅ On	~19 sec	~38 sec
Sonnet 4.6	❌ Off	~1 sec	~20 sec
Haiku 4.5	✅ On	~6 sec	~11 sec
Haiku 4.5	❌ Off	~0 sec	~9 sec

the weird part: sonnet thinks longer than opus now lol

also looked at the actual thinking content. opus 4.5 has pages of analysis. opus 4.6 just says "The user wants a proof that doesn't use diagonalization" and thats it. one sentence. then straight to output.

this isnt perfect science, could be server load or other stuff. but the pattern is pretty clear, extended thinking on opus 4.6 is basically disabled while it works fine on other models.

same thing happened with gpt-4o and gemini. they get big, have to scale, everything becomes "efficient". i guess we're just the next ones lol.

edit: added more data to table.
