Its lab's numbers put it at 137.2, number 206 of 404

The Self-Reported Index fits one score to the 8 capability results Deep Cogito reported for this model, on the scale of the Epoch Capabilities Index. Labs choose which benchmarks to show and how to run them, so read it as the lab's claim, not an independent measurement. The 90% interval runs from 134.0 to 140.3. How we compute it.
