UI-TARS 7B API pricing
bytedance · Budget price tier · Apache 2.0 · released 2025-07. Prices in USD per 1 million tokens. Data snapshot: 2026-11-12.
A support ticket workload of 100K requests a month costs $25.00 on UI-TARS 7B; the next cheaper model in the Budget price tier for this workload, Llama 3.2 3B Instruct, does it for $24.00. UI-TARS 7B has held the same list price since 2026-08-15 and is the 33rd cheapest of 160 models in the Budget price tier. Only one host, Parasail, sells it, so there is no second price to shop. No Arena score is published for it, so it carries no Efficiency score and cannot hold the FinOps Friendly badge.

Market position
On blended price ($0.17 per 1M tokens at 30% input, 70% output) it is cheaper than 78% of models in the Budget price tier: 33rd cheapest of 160, tied with 3 others. Across every price tier it is cheaper than 88% of priced text models in the catalogue: 33rd cheapest of 303, tied with 3 others. No Arena score has been published for UI-TARS 7B, so this page does not rank it on quality and OptimNow's quality bars do not apply to it. 77 of the 160 models we list in the Budget 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
UI-TARS 7B is open source: its weights are published under Apache 2.0, an OSI-approved licence with no field-of-use limit, so it can be self-hosted as well as bought by the token. Its published size is 7B parameters. Listed capabilities: Text, Vision. Filling its 128K context window once costs $0.0128 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.
Parasail is the only host with a published rate, $0.10 input / $0.20 output per 1M tokens, which is the price we quote.
| Host | Input $/1M | Output $/1M | Precision |
|---|---|---|---|
| Parasail (price we quote) | $0.10 | $0.20 | bf16 |

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.
