I tried Fable 5.2 tonight, asking it for a code review of an in-browser machine vision project done by Opus 5.5 over the last 11 days. It used up my 5-hour token budget in half an hour and reported 7 serious bugs; if they're real, they're pretty bad. It's also suggesting that I take a different overall approach to parts of the problem.
But that's just a first impression.
When Fable 5.3 comes out and you give it the same prompt it will take 10 hours , cost twice as much and still find pretty bad problems. I say stick to Opus...
> But that's just a first impression.
Your first impression is that you have no clue if any of its findings actually mean anything because you can't even understand them or the vibe coded slop you've been creating? Why would anyone care?
Scary stuff! You should immediately get another subscription and ask another instance of Fable 5.2 to review the findings (don't read them yourself, it will introduce bias in the super AGI's output)
