Qwen 3.8 Max vs GLM-5.2
Values come from Qwen 3.8 Max and GLM-5.2, where each is cited to its source. This page states no benchmark result and ranks neither model — it puts two published specifications next to each other. Where a lab has not published a figure, the row says so rather than guessing.

What actually differs
- Context window
- Identical — both accept 1M tokens, so context length is not a reason to pick either.
- Input price
- GLM-5.2 at $1.4/M against $2/M — 1.4× cheaper to feed.
- Output price
- GLM-5.2 at $4.4/M against $6/M — 1.4× cheaper to generate. Output dominates the bill on most agentic workloads, where the model writes far more than it reads.
- Weights
- Both publish weights — Qwen 3.8 Max under Open-weight announced for the week of 2026-08-10; not yet shipped, GLM-5.2 under MIT (unrestricted, "no regional limits"). Check the licences rather than assuming they permit the same commercial use.
- Recency
- Qwen 3.8 Max shipped 51 days after GLM-5.2 (2026-08-03 vs 2026-06-13).

| Pricing | $2 / M input · $6 / M output | $1.40/M input · $4.40/M output — Z.ai's own endpoint on the OpenRouter catalogue, read 2026-08-01. Earlier revisions of this row quoted ≈$0.62–$0.77, which was not a price change: OpenRouter serves this model from 33 providers between $0.72 and $2.31 on input, and `/models` reports whichever one is routing at that instant. Four alerts in a day named $0.97, $1.19, $1.12 and $0.76 — Alibaba, SiliconFlow, an intermediate route, and StreamLake. Reseller quotes are real prices but they are not this model's price; quote the first-party figure, or quote a reseller with its name attached. |
