flysim is a foraging world where a fruit-fly has to find sugar and dodge a predator, and you swap out who makes the decisions. I put two decision layers in it and ran them at the same time. Same world, same body, same predator — concurrent, not lockstep. Jev by @typesafeai lived 30 ticks in 13.2 seconds for $0.000834. gpt-6-astra took 101.9 seconds and $0.121280. 145x the cost. 7.7x per decision.

The comparison used the same body and predator, but was not lockstep. Jev lived 30 ticks while gpt-6-astra took 101.9 seconds; the author reported gpt-6-astra cost 145x more and 7.7x per decision.
