Nex-N2.5-Pro API pricing
nex-agi · Budget price tier · Apache 2.0 · released 2026-09. Prices in USD per 1 million tokens. Data snapshot: 2026-11-12.
A support ticket workload of 100K requests a month costs $23.75 on Nex-N2.5-Pro; the next cheaper model in the Budget price tier for this workload, DeepSeek V4.1 Flash, does it for $23.30. Nex-N2.5-Pro has held the same list price since 2026-09-22 and is the 41st cheapest of 160 models in the Budget price tier. Only one host, Nex AGI, 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 ($0.1975 per 1M tokens at 30% input, 70% output) it is cheaper than 75% of models in the Budget price tier: 41st cheapest of 160. Across every price tier it is cheaper than 87% of priced text models in the catalogue: 41st cheapest of 303. No Arena score has been published for Nex-N2.5-Pro, 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
Nex-N2.5-Pro 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 parameter count is not published. Listed capabilities: Text, Vision, Reasoning, Agents. Filling its 262K context window once costs $0.0197 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.
Nex AGI is the only host with a published rate, $0.075 input / $0.25 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 |
|---|---|---|---|
| Nex AGI (model maker, price we quote) | $0.075 | $0.25 | fp8 |

Monthly cost at 100K requests, by business use case
From the after-discounts figure (prompt caching on the cached input share, batch API for async workloads, only where nex-agi publishes those rates), which assumes you implement both, to the list price. One figure means no discount is published.

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.
