Write and analyze with Step 5 Preview
Step 5 Preview is StepFun's flagship model, released on 20 September 2026: six hundred billion parameters in a mixture-of-experts architecture, twenty-seven billion of them active per token, a one-million-token context and image reading. It targets professional work in the broad sense, documents, applications, financial analysis, and delivers complete pieces in one pass rather than drafts to rework. On the canvas, hand it structured briefs, a presentation file, a costed study, a specification, where its rigour matters more than style. Its price sits in the mid range, below Grok 4.7.

It targets professional work in the broad sense, documents, applications, financial analysis, and delivers complete pieces in one pass. It thinks at length before answering, even a short question: on the canvas, keep it for structured briefs, a presentation file, a costed study, a specification, where its rigour matters more than speed.

Frequently asked questions
Why does Step 5 Preview take time to answer?
It reasons before writing, even on simple requests: a minute for one word in our probe. That is the price of its rigour on long files; for an instant answer, MiMo V2.6 Flash or Mercury 2.5 are built for that.
How much does a message sent to Step 5 Preview cost?
Around 1 credit(s) per message, that is $0.01 (1 credit = $0.012). The cost shows before sending, with no separate subscription and no API key to manage: the same credits pay for all 105 models in the catalog.
Do I need a separate subscription to use Step 5 Preview?
No: Step 5 Preview is included in Imaginode, with no API key and no account with the provider. A single credit balance covers all 105 models, text, image, video and voice, and also powers the assistant that builds complete workflows.
Can I try Step 5 Preview for free?
Yes: signing up grants trial credits, no credit card required. Enough to test Step 5 Preview in real conditions before deciding on a plan or a top-up.
Do I need to install anything to use Step 5 Preview?
No: Step 5 Preview runs server-side, in the browser, mobile included. Imaginode's node canvas wires its renders to the other models (references, camera, styles) with nothing to install.
