The Self-Reported Index fits one score to the 5 capability results Arcee AI 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 93.1 to 105.6. How we compute it.
