GLM-5.1 vs Qwen3-Max
Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.
Z.ai (Zhipu) · Apr 2026
The April 2026 GLM refresh — the first open-weights model to take #1 on SWE-bench Pro, edging out Claude Opus 4.6.
Alibaba (Qwen) · Sep 2025
Alibaba's trillion-parameter API flagship — frontier-adjacent quality with strong agentic tool use at mid-tier prices.
The verdict
These two models don't yet share verified results on the benchmarks we track, so judge them on specs, pricing and intended use. GLM-5.1 is about 1.1x cheaper per blended million tokens (3:1 input:output mix). Qwen3-Max also takes 262K of context versus 200K for GLM-5.1. And GLM-5.1 is open-weights (MIT), so it can be self-hosted — a structural advantage if data control or vendor independence matters.
Specs & pricing
| GLM-5.1 | Qwen3-Max | |
|---|---|---|
| modhub Index | — | 80.5 |
| Input price / 1M | $1.4 | $1.2 |
| Output price / 1M | $4.4 | $6 |
| Context window | 200K | 262K |
| Max output | 128K | 66K |
| Open weights | yes (MIT) | no |
| Reasoning model | yes | yes |
| Multimodal input | text | text |
| Knowledge cutoff | Feb 2026 | Jun 2025 |
| Released | Apr 2026 | Sep 2025 |
| Example monthly cost* | $20.60 | $21.00 |
* 10M input + 1.5M output tokens per month at list prices, no caching. Green = better value on that row.
