Qwen3.5-9B 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 6 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.
Cheapest host: Darkbloom at $0.08 input / $0.13 output per 1M tokens, 15% below the price we publish on a blended basis (30% input, 70% output). It serves a quantized fp4 build, which is not the same product as the full-precision model. The dearest, Together, charges 2.0x the cheapest.
| Host | Input $/1M | Output $/1M |
|---|---|---|
| Darkbloom — fp4 | $0.08 | $0.13 |
| SiliconFlow (the price shown above) — fp8 | $0.10 | $0.15 |
| DeepInfra (the price shown above) — bf16 | $0.10 | $0.15 |
| Venice (the price shown above) — fp8 | $0.10 | $0.15 |
| Parasail — bf16 | $0.10 | $0.25 |
| Together | $0.17 | $0.25 |
