About this vendor
Vendor-level selection advice by Y-API. The per-model pages linked below carry the model-specific checks; nothing here is a measured comparison.
Where this vendor fits
DeepSeek is the price floor of this catalog: three of its four entries cost under $0.25 per million input tokens, and the free Flash preview makes it the default first call when validating a Y-API integration before spending credit.
What to watch for
The dated IDs (0423, 0731) are catalog entries, not a subscription to the newest checkpoint, so saved evaluations stay tied to the exact ID. Free status is also upstream’s choice and can be withdrawn — production assumptions must not rest on a $0 price.
Models on Y-API
Prices are account-credit snapshots from the Y-API catalog. Each model links to its own guide with a cost estimator and a request example.

Account credit / Cash equivalent · $1 paid adds $10 of credit; the cash equivalent is credit consumed ÷ 10. These are Y-API prices, not the publisher’s list prices.
Choosing within the lineup
Start on V4 Flash 0731, the maintained Flash revision. Move to V4.1 Flash only when the task needs image input, and reserve V4 Pro for workloads where the cheaper entries demonstrably miss. Keep the free 0423 preview for smoke tests rather than reusable baselines.
Before you choose
Which DeepSeek model should a new integration start with?
V4 Flash 0731: it is the publisher’s official Flash release and among the cheapest paid entries in the catalog. Validate the integration there, then add image input through V4.1 Flash or move to V4 Pro only where the task shows a gap.
