Nebius FAQ

How does Nebius' tier-based rate limiting work?

New users start at a lower tier with conservative limits. As you build usage history (consistent, non-abusive usage), your tier and limits increase automatically. This is similar to a trust-based system.

Is Qwen3-235B on Nebius really 235 billion parameters?

Yes — Qwen3-235B-A22B is a Mixture-of-Experts model with 235B total parameters (22B active per token). It's one of the largest models available on any free tier and competes with GPT-4 class models.

Is Nebius better than OVHcloud for EU hosting?

Both are EU-hosted and GDPR-compliant. Nebius offers larger models (Qwen3 235B) while OVHcloud offers more model variety and an anonymous tier with no registration. Choose based on which models you need.
