DeepSeek V4 Flash 0423 pricing by host
A host is a company that runs the model and sells it by the token — the lab that made it, a cloud platform like Amazon Bedrock, Azure or Vertex, or an independent provider. One model, several sellers, and often several prices. This model is sold by 15 different hosts. The price quoted above is the one we publish so that models stay comparable; it is not necessarily the cheapest way to buy this model. List prices as published on 2026-09-28 via OpenRouter — negotiated rates, committed-use discounts and provisioned capacity are not shown. These hosts do not all serve the model at the same numeric precision, so the cheapest is not a like-for-like substitute for the dearest.
The price we publish is already the cheapest of the 15 hosts: StreamLake at $0.09 input / $0.17 output per 1M tokens. It serves a quantized fp8 build, which is not the same product as the full-precision model. The dearest, Relace, charges 6.1x the cheapest.
| Host | Input $/1M | Output $/1M |
|---|---|---|
| StreamLake (the price shown above) — fp8 | $0.09 | $0.17 |
| Baidu (the price shown above) — fp8 | $0.09 | $0.18 |
