StepFun models and prices
2 models, 2 with a published price · released 2026-01-29 to 2026-05-28.
You can buy from StepFun directly, or from 4 other hosts
We hold offerings sold by StepFun itself as well as by independent hosts. Buying direct is not automatically the cheapest route, and it is not automatically the same product either — hosts differ on quantisation, served context window and rate limits.

One API for every StepFun model
VernaOne fronts the sellers on this page behind a single interface, so switching model or host is a config change — with automatic fallback if quality or latency regresses.

Newest first, priced or not. A model with no price is a fact about what its sellers publish, not a gap we are hiding.

Frequently asked
How many models does StepFun have?
We track 2 StepFun models across 1 category, 2 of them with a published price. The list is rebuilt from provider APIs, the vendor's own docs and the weights registry rather than maintained by hand, so new releases appear without us writing about them.
Can I buy StepFun models directly from StepFun?
Yes — we hold offerings sold by StepFun itself (as stepfun), alongside 4 other hosts. Buying direct is not automatically cheapest: each model page lists every seller with its price and the evidence behind it.
Are StepFun models open weights?
None of the StepFun models we track publish weights, so they can only be used through an API.
