## How they compare

Alibaba Cloud and StreamLake are both AI arms of large Chinese internet companies, but their catalogs point in different directions. Alibaba's Model Studio serves the Qwen family, led by Qwen 3.8-Max with 1M context and text, image and video input at $2 in and $6 out internationally, with open Qwen models too. StreamLake, Kuaishou's AI cloud, leads with KAT-Coder-Pro V2.5, a proprietary agentic coding model that StreamLake says was trained with large-scale RL for repository-level work. It sells per token or through a KwaiKAT Coding Plan, with a Claude-protocol proxy for Claude Code.

For Western buyers, Alibaba is easier. It offers regional deployment scopes including the EU and international pricing in dollars, while StreamLake's pricing and documentation lead with China and yuan, and its data stays in China. Both sell compute beyond models, Alibaba as a full hyperscaler and StreamLake as bare metal for Chinese internet businesses. General multimodal and multilingual products fit Alibaba. A developer wanting a subscription coding plan inside Claude Code, or a Chinese business wanting domestic MaaS, fits StreamLake.

## What each one does

### 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.

### StreamLake

StreamLake is the AI cloud brand of Kuaishou, the Chinese short-video company behind the Kling video models. It sells model-as-a-service inference and bare-metal compute to internet businesses, drawing on the infrastructure Kuaishou built to serve video at massive scale. Its developer site offers APIs, SDKs and integration guides aimed at taking teams from testing to production.
