I just asked Fable to do a task that has nothing to do with cybersecurity or is dangerous at all but the defense kicked in and it switched to Opus... :(
The benchmarks are very impressive. Codex and Opus 4.5 are really good coders already and they keep getting better.
No wall yet and I think we might have crossed the threshold of models being as good or better than most engineers already.
GDPval will be an interesting benchmark and I'll happily use the new model to test spreadsheet (and other office work) capabilities. If they can going like this just a little bit further, much of the office workers will stop being useful.... I don't know yet how to feel about this.
Great for humanity probably but but for the individuals?
I have canceled my Claude Max subscription because Sonnet 4.5 is just too unreliable. For the rest of the month I'm using Opus 4.1 which is much better but seems to have much lower usage limits than before Sonnet 4.5 was released. When I hit 4.1 Opus limits I'm using Codex. I will probably go through with the Codex pro subscription.
They also managed to introduce regressions into WebKit so that the visual and touch positions of fixed input elements diverge. Really makes you question what’s going on at Apple.
