Frequently asked questions

Is Nex-N2-Pro as good as o1-pro (batch)?

Nex-N2-Pro is open-weight and competitive on many tasks, but o1-pro (batch) may still lead on the hardest reasoning and agentic work. The gap keeps narrowing — benchmark both on your actual use case before deciding.

Can I run Nex-N2-Pro locally?

Yes. Nex-N2-Pro has open weights, so you can self-host it on your own GPUs or run it via a low-cost API. o1-pro (batch) is API-only and cannot be self-hosted.

How much cheaper is Nex-N2-Pro?

Nex-N2-Pro costs $1/M output vs $300/M for o1-pro (batch) — roughly 300x cheaper via API, and free if you self-host.

Nex-N2-Pro vs o1-pro (batch) — which should I pick in 2026?

Choose Nex-N2-Pro if you want to self-host, keep your data private and skip per-token fees — it's open-weight and runs on your own hardware. Choose o1-pro (batch) if you want frontier capability through a managed API with zero infrastructure to run.
