Damn, im in love with Opus 5.5. Its the best model ive ever used, has such a good taste, is comparatively quickly, smart and finally precise instead of verbose.
As good as Opus 5.5 is, I'm incredibly excited for Fable 5.5. After switching completely to Codex, I now have to go back to Anthropic.
oh and btw. its crazy how fast the vibe has changed.
Now all I read on X are posts about how great Opus tastes and how OpenAI absolutely has to catch up.
One day that changed everything.
damn, this is brutal for Fable 5.1
on CursorBench 4.0: opus 5.5 medium beats fable 5.1 max while costing nearly 6x less and using 68% fewer tokens
52.5% vs 51.8%
$2.91 vs $17.28 per task
37.9k vs 117.2k tokens
that efficiency gap is insane
