1 model built · 1 served
Nex is an open-source agentic-AI alliance initiated by the Shanghai Innovation Institute, based in China. The group is known for the Nex-N series, models built specifically for agentic workflows and coding tasks rather than general chat. On OpenKey there's currently one Nex model available: Nex-N2-Pro, released June 8, 2026. It's a text+image-to-text model with a 262,144-token context window, priced at $0.25 per 1M input tokens and $1.00 per 1M output tokens. It ranked 8th on the Design Arena SVG benchmark with an Elo of 1279, suggesting real strength in structured/visual generation tasks tied to coding.
Lineup
With only one model in the lineup, the choice is simple: use Nex-N2-Pro. It's priced at $0.25/1M input and $1.00/1M output on OpenKey (provider price × 1.03: $0.2575 input, $1.03 output), which is cheap enough for agentic pipelines that make heavy input-token use — tool calls, retrieved context, multi-step planning. The 262K context window supports long agent traces or large codebases in a single call. Given its SVG/design benchmark ranking, it's a reasonable pick for coding and layout-generation tasks specifically, not just general-purpose chat.

Questions
- How much does Nex-N2-Pro cost on OpenKey?
- Nex-N2-Pro is $0.25 per 1M input tokens and $1.00 per 1M output tokens from the provider. On OpenKey that's provider price × 1.03: $0.2575 per 1M input and $1.03 per 1M output. There's no free Nex model available.
- Which Nex model should I use?
- There's only one: Nex-N2-Pro. It handles text and image input, outputs text, and supports a 262,144-token context window. It's built for agentic and coding workloads and ranked 8th on the Design Arena SVG benchmark (Elo 1279), so it's a solid default for that use case since there's no alternative in the lineup.
- Does OpenKey support Nex's API?
- Yes — Nex-N2-Pro is accessible through OpenKey's single API key alongside the other 328 models on the platform. You get provider list pricing plus a flat 3% fee, no separate Nex account or billing setup needed.
