Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.
Anthropic · Mar 2026
The early-2026 Opus release that pushed SWE-bench past 82% and extended the 1M context to the whole Opus line.
Z.ai (Zhipu) · Sep 2025
The budget coding-agent favorite of late 2025 — near-Sonnet coding utility with MIT weights and a $3/month plan.
The verdict
Claude Opus 4.7 wins 1 of the 1 benchmarks these models share, against 0 for GLM-4.6. On price the gap is dramatic: GLM-4.6 works out roughly 10x cheaper per blended million tokens. Claude Opus 4.7 also takes 1M of context versus 200K for GLM-4.6. And GLM-4.6 is open-weights (MIT), so it can be self-hosted — a structural advantage if data control or vendor independence matters.
