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: 14.5 (Artificial Analysis composite across reasoning, knowledge and coding evals)
- AA Agentic Index: 2.9 (Tool use, planning, autonomy)
- AA-Omniscience Index: -53.4 (−100–100)
- Ranks #125 of 150 comparably-measured models by percentile score, across 3 independent measurements
- Ranks #50 of 150 comparably-tested models by normalized performance per dollar
