## How they compare

Both labs sell their own models, but they draw the open line in different places. Z.ai's flagship GLM-5.3 costs $1.40 in and $4.40 out and belongs to a family with MIT-licensed weights. Alibaba's flagship Qwen 3.8-Max is proprietary, at $2 in and $6 out internationally, while its smaller Qwen models ship open. Max takes text, image and video input with a 1M window and built-in web search. Z.ai's listing centers on text and coding, with the GLM Coding Plan from $18 a month and an Anthropic-compatible endpoint that lets Claude Code run on GLM.

Free access works differently on each side. Z.ai prices several older Flash models at zero, a standing free tier. Alibaba gives a free 1M token quota per model for 90 days and runs promotions like night-time cuts of up to 80% on Qwen 3.7-Max. Region is the bigger split. Z.ai's servers sit mostly in China, adding 100 to 200ms from the US or Europe, while Alibaba offers regional deployment, including the EU, inside a full public cloud. Alibaba's price sheet is harder to read, with region scopes and date-stamped model IDs.

## What each one does

### Z.ai

Z.AI is the international brand of Chinese lab Zhipu AI, maker of the GLM models. Its current flagship, GLM-5.3, shipped August 17, 2026 at $1.40 in and $4.40 out per million tokens, with cached input at $0.26. GLM-5.3-Flash costs $0.075 in and $0.25 out, and several older Flash models are priced at zero, a real free tier instead of trial credits. GLM-5, released in February 2026, is a 744B mixture-of-experts model under an MIT license, and at launch it ranked first among open-weight models on the Artificial Analysis index with a record-low hallucination score.

### Alibaba Cloud

Alibaba Cloud serves the Qwen model family through Model Studio, its managed AI platform. The flagship Qwen 3.8-Max takes text, image and video input with a 1M token context, function calling, structured outputs and built-in web search. International pricing is $2 in and $6 out per million tokens, with implicit cache hits at $0.25. Deployments in China and some global regions list lower, at $1.65 in and about $4.95 out, and Alibaba often runs limited-time discounts, including night-time cuts of up to 80% on Qwen 3.7-Max.
