OpenAI O3 breakthrough high score on ARC-AGI-PUB
Models in practice haven't been deterministic at 0 temperature, although nobody knows exactly why. Either hardware or software bugs.

We know exactly why, it is because floating point operations aren't associative but the GPU scheduler assumes they are, and the scheduler isn't deterministic. Running the model strictly hurts performance so they don't do that.
