None of the tweets, nor the press release, seems to mention how long time it actually took E2E to complete the evaluation, but they do mention it took "12% fewer actions" compared to just Opus 5 without AVO. Feels a bit suspicious they don't break down the timing involved, looking at the diagram from the press release, it gives the impression there is a lot of machinery here, and given they claim fewer actions, each action must be more carefully considered, doesn't it?

Curious to read more about it though, seems the paper for it is here: https://arxiv.org/pdf/2603.24517, I'm not sure I understand if it's better than just Codex with a /goal, as they talk about "can discover performance-critical micro-architectural optimizations" but leave Codex alone for a day or two and you'll get the same results without doing "additional autonomous adaptation" at all.
