Alibaba Cloud vs Wafer: key differences
Wafer's showcase model is an open Qwen. It reports its tuned Qwen 3.5 397B running 2.8x faster than stock SGLang, a self-reported number against an untuned baseline. Its agents tune batching, decoding, quantization, kernels and hardware for each deployment, on NVIDIA or AMD, and its serverless API, billed per token, works inside Claude Code, Cline or OpenHands. Alibaba Cloud serves Qwen directly, including the hosted Qwen 3.8-Max with 1M context and multimodal input at $2 in and $6 out internationally.
The two serve different needs. Wafer suits developers who want big open GLM or DeepSeek models at interactive speed, and teams with a strict latency SLO that want a dedicated deployment tuned for them. Alibaba suits anyone who needs the hosted Max tier, video input, regional deployment including the EU, or a full cloud around the model. Wafer is a very young company with a small hosted catalog. Alibaba is large but has a confusing price sheet with rotating promotions.
What Alibaba Cloud and Wafer do
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.
Example models: Qwen 3.8-Max, Qwen 3.7-Max
Full Alibaba Cloud profileWafer
Wafer builds AI agents that act as GPU performance engineers, then sells inference on the stacks those agents tune. The company came out of Y Combinator's Summer 2025 batch as a "Cursor for CUDA" that turned slow PyTorch into custom kernels. Founders Emilio Andere and Steven Arellano are based in San Francisco. Wafer raised a $4M seed led by Fifty Years in April 2026 and a $40M Series A co-led by Marathon and Chemistry in September 2026 at a $220M post-money valuation, with AMD Ventures and Wing joining. Its agents profile a workload, generate candidate configs across batching, decoding, quantization, engines, kernels and hardware, measure each one and deploy the winner.
Example models: GLM-5.3, DeepSeek V4.1 Flash
