Field notes
The site organizes models by capability bands rather than treating lowest energy as an absolute winner. Its comparison includes model-level caveats: some calculations use estimated parameter counts, while Grok 4 spans 65.3 to 1019 Wh because xAI has not disclosed enough about how it is built. Capability context also includes a 58-benchmark index and, where available, head-to-head votes from LMArena.
