Capabilities
struck through = not supportedBenchmark performance
accuracy % · higher is betterWe hold no per-benchmark accuracy scores for this model yet, so it has no accuracy average. That is a gap in our coverage, not a sign the model is untested — independent evaluators often publish a composite index for a new model long before releasing its per-benchmark numbers. The percentile above is its standing across the independent composites below.
- AA Intelligence Index: 5 (Artificial Analysis composite across reasoning, knowledge and coding evals)
- Ranks #144 of 150 comparably-measured models by percentile score, across 1 independent measurement
- Ranks #148 of 150 comparably-tested models by normalized performance per dollar
