Its lab's numbers put it at 127.6, 5.4 points below its ECI

The Self-Reported Index fits one score to the 12 capability results Google DeepMind 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 125.2 to 130.0. How we compute it.
