Their point estimates differ by 4 points. The displayed ranges overlap; this is not a test of task-specific superiority or a guarantee about a different configuration.

The former composite, MMLU and cost-per-capability recommendations are withdrawn because their inputs included unsupported estimates. No upgrade or overall capability recommendation is made from those numbers.

Price quotes are from the selected provider registry checked 2026-10-22. Unverified legacy quotes are withheld. Use the token calculator for input, output, cache-hit and context-tier scenarios. Additional service charges and account-specific terms can change a bill. Missing pricing evidence does not mean free inference.
