> a team of 1,000 Fable 5.2 agents

Genuinely curious what that costs in terms of energy input and amortized computer cost vs. the previous version + a human's salary for 11 days.

Yes, and not very helpful without knowing how many agents were used by the custom-built harness. The 30 hrs vs. 11 days means nothing without at least some token-to-token comparison. Without that, they are pumping up their new model with half data - better to just say "we solved it in 30 hours" and who cares about your internal, custom model.
