Why we recommend StepFun
StepFun (Shanghai StepFun Intelligent Technology Co., Ltd.) is a Shanghai AI lab founded in 2023, with Step series focused on multi-modal + fast inference. The 2026 flagship Step 3.7 Flash is strong on text and also leads on video understanding, speech synthesis (StepAudio Realtime TTS), image understanding, and multi-modal Agent operations.
Step Plan is the personal subscription (4 tiers, ¥49-699/mo) with a unified Credit pool (1 Credit ≈ 1 Token).
| Tier | Monthly | Credits / month | Notes |
|---|---|---|---|
| Flash Mini | ¥49 / month | 400M | Entry-level, 2× OpenAI Go quota |
| Flash Plus | ¥99 / month | 1,600M | Daily-use, priority API rate |
| Flash Pro | ¥199 / month | 8,000M | Pro tier |
| Flash Max | ¥699 / month | 40,000M | Top tier |
All 4 tiers support the full flagship model lineup + intelligent routing + multiple MCP tools. Plus adds priority API rate + priority tech support.
In practice, platform.stepfun.com is the single entry point — subscription and API calls live on the same domain (unlike Qwen's brand + console split). The companion Studio creative platform adds an extra 40% of Step Plan quota for creative work.
On performance, Step 3.7 Flash is one of 2026's standout speed + value plays. Per the developer reviews on the Step Plan page: Step 3.7 Flash hits 96% pass-rate on multi-modal Agent tasks (UI / captcha / multi-step ops), with full-pipeline delivery stability — a critical foundation for Agent-to-Agent (A2A) collaboration.
If your project needs multi-modal Agent capability + fast inference + value pricing + reliable China access + unified Credit pool, Step Plan is a strong 2026 pick.
