Astra 6 is so completely brutally better than Opus 5.5 at formal verification it's not even funny
I'm using TLA to verify something we will be launching soon, and... man Opus is getting completely fried and Astra is just cruising.
@bolayer Speed and UX mostly
Fable has historically been super slow in my experience and also previously had a hard time on this task (have not tried 5.2 though!)
So the models I use are Astra and Opus
Astra is fast enough for me
@luisguimontmota Not for me I guess. I still have to think through solving it, but astra very very quickly takes what I say and implements it in the quint format
@lisi288917 Yes. This is something like a mathematical proof. In fact I can run it through a proof engine I'm just not doing it.
The TLA model checker does brute force search to find traces where rules for the system fail
I think for this task it might also be in token consumption
It took opus much longer time wise to give me a correct result and if we assume a relatively equal rate of burn then for it to be equal it would simply need to take me 2.5 x as long with opus
Which feels approximately true but again Iβm going off of vibes since I didnβt time wall clock time or check my initial usage for either
Certainly opus spent more tokens but the cost difference is massive so itβs unclear who comes out on top
