Nebius sells two products relevant to an API-pricing decision: Token Factory, an OpenAI-compatible inference API for open models (where each model is offered in a default and a -fast flavor with different latency and token pricing), and GPU instances billed per GPU-hour, from $2.15 for preemptible H100 up to $7.85 on-demand for HGX B300. The public pricing page documents instance, storage and network rates plus billing rules; Token Factory per-token prices are only shown after login. Commitment reservations are advertised at up to 35% below on-demand rates.

No free tier or USD sign-up credit is stated on official pages (checked 2026-09-16); the docs describe promo codes that grant free credits only when Nebius issues one in a special offer, and the first card payment is $25 credited to the account balance.
