BenchLM does not treat an alternative query like a generic leaderboard. This page starts from the tracked Claude Sonnet 4.6 reference, then weights benchmark quality, token cost, context window, and deployment model to find realistic replacements.
That means a model can outrank the absolute leaderboard leader here if it stays close enough on benchmarks while being materially cheaper, more open, or better matched to the workflow implied by the query.
Change the goal, use case, or minimum context if this landing page is close but not exact.
