What the evidence supports
The recorded entries are GLM-5.2 (Max) (1476 ± 4) and GPT-6 Astra (Max) (1476 ± 6).
Their point estimates differ by 0 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The former composite, MMLU and cost-per-capability recommendations are withdrawn because their inputs included unsupported estimates.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.
Before choosing a deployment
Use the exact configuration you would deploy on a fixed set of representative tasks. Record accepted answers, failures, end-to-end latency and total metered cost. Check licensing, hosting options and data requirements directly with each provider. This is a proposed evaluation procedure; AI Mastery has not run a head-to-head workload test for this pairing.
The leaderboard records the verified variants and withheld columns. The separate benchmark matrix contains dated provider disclosures and needs its own source/version review.
