A support ticket workload of 100K requests a month costs $200.00 on Seed 2.1 Turbo; the next cheaper model in the Mid-range price tier for this workload, R1 0528, does it for $182.50. Seed 2.1 Turbo has held the same list price since 2026-08-15 and is the 24th cheapest of 113 models in the Mid-range price tier. Only one host, Seed, sells it, so there is no second price to shop.

Market position
On blended price ($1.90 per 1M tokens at 30% input, 70% output) it is cheaper than 79% of models in the Mid-range price tier: 24th cheapest of 113. Across every price tier it is cheaper than 39% of priced text models in the catalogue: 184th cheapest of 303. No Arena score has been published for Seed 2.1 Turbo, so this page does not rank it on quality and OptimNow's quality bars do not apply to it. 66 of the 113 models we list in the Mid-range price tier carry one. An unranked model is unmeasured, not poor: the benchmark needs votes, and a recent release has not had time to collect them.
Licence, size and capabilities
Seed 2.1 Turbo is recorded here as proprietary: access is through an API, priced by the token. Its parameter count is not published. Listed capabilities: Text, Vision, Reasoning, Agents. Filling its 262K context window once costs $0.131 in input tokens at list price.
Pricing by host
A host is a company that runs the model and sells it by the token: the model maker, a cloud platform like Amazon Bedrock, Azure or Vertex, or an independent host. One model, several hosts, and often several prices. This model is sold by 1 host. The price we quote elsewhere on this page is marked. We quote one host's rate so that models stay comparable; it is not a recommendation to buy there.
Seed is the only host with a published rate, $0.50 input / $2.50 output per 1M tokens, which is the price we quote. It serves a quantized fp8 build, which is not the same product as the full-precision model.
| Host | Input $/1M | Output $/1M | Precision |
|---|---|---|---|
| Seed (model maker, price we quote) | $0.50 | $2.50 | fp8 |

Monthly cost at 100K requests, by business use case

These are list prices. Your real cost also depends on caching and batching, negotiated discounts, marketplace agreements, and the contracts you already have. OptimNow audits exactly that.
