## How they compare

Alibaba Cloud and StepFun both build multimodal models that read images and video, and both release open weights for some models. Alibaba's flagship Qwen 3.8-Max is closed, with 1M context, function calling and web search at $2 in and $6 out internationally. StepFun's Step 3.7 Flash is open under Apache 2.0, a 198B mixture-of-experts model with 11B active parameters and 256K context at $0.20 in and $1.15 out on StepFun's API. On price per token and self-hosting cost, StepFun is far ahead.

Capability and distribution favor Alibaba. StepFun trails frontier models on hard multimodal reasoning benchmarks, has thin Western distribution and support, and runs first-party inference in China, though OpenRouter carries its model. Alibaba offers regional deployment scopes including the EU and a full public cloud, with open Qwen models for self-hosting as well. StepFun also builds speech and audio models. Cost-sensitive vision and video agents, and teams that want a cheap model to self-host, fit StepFun. Enterprises needing longer context, regional control and a stronger flagship fit Alibaba.

## 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.

### StepFun

StepFun is a Shanghai AI lab known for efficient multimodal models, with a mix of proprietary API models and open-weight releases. Its current workhorse, Step 3.7 Flash, came out in May 2026 as a 198B mixture-of-experts vision-language model with only 11B active parameters. It has 256K context, selectable reasoning levels, tool use and structured outputs, and it ships under Apache 2.0. StepFun's own API prices it at $0.20 in and $1.15 out per million tokens, and OpenRouter carries it too.
