What moved

Flash Mini, Flash Plus, Flash Pro and Flash Max served Step 3.7 Flash and Step 3.5 Flash only → Step 5 Preview added to Flash Mini, Flash Plus, Flash Pro and Flash Max at $1.00/$2.70 per 1M (cache read $0.05; 7 / 0.35 / 18.9 credits per token at the published $1 ≈ 7M credits)

StepFun's Step Plan overview now lists step-5-preview first in "Step Plan currently supports the following models" as "flagship model for agentic work", and guides/pricing/details publishes its row (1M context, $1.00 cache-miss input / $0.05 cache-hit input / $2.70 output per 1M tokens — the cache-miss price includes writing new content to the cache). The quick-start page recommends step-5-preview for a first integration. The same published rates therefore flow into all four credit tiers as 7 / 0.35 / 18.9 credits per token; monthly prices, credit allowances, booster packs and the $1 ≈ 7M conversion are unchanged, and step-3.5-flash-2603 remains a dated alias of Step 3.5 Flash rather than a new roster entry.
