## How they compare

Nebius is the strongest European alternative to the US hyperscalers, and that framing matters here. It sells raw NVIDIA GPUs, from H100s at $2.15 an hour preemptible up to GB300 NVL72 racks, and runs Token Factory, a managed service for 60+ open models from $0.06 per million input tokens. Dedicated endpoints carry a 99.9% SLA with optional EU or US placement. Vertex AI is Google Cloud's platform: Gemini 3.8, Claude and 200+ models, custom training on GPUs or TPUs, vector search, and an agent runtime with Memory Bank.

The choice follows model type and jurisdiction. Nebius serves open weights only, so a team that needs Gemini or Claude has to look elsewhere. A team that wants open models kept in the EU, fine-tuned checkpoints served at base token prices, and a path from tokens into training on raw GPUs gets a cleaner offer from Nebius. Vertex brings more tooling but also Vertex-native lock-in and hard-to-forecast pricing. Nebius has its own friction: no free trial and a $25 minimum first payment, where Vertex offers new accounts up to $300 in credits.

## What each one does

### Google Vertex AI

Vertex AI is Google Cloud's enterprise AI platform. At Google Cloud Next on April 22, 2026, Google rebranded it the Gemini Enterprise Agent Platform with an agent-first structure, though the API endpoint and most docs still say Vertex. Model Garden offers 200+ models, including Google's Gemini 3.8 family, Anthropic's Claude models and open models like Gemma, alongside Imagen, Veo and Chirp for media and speech. Google's own TPUs sit underneath much of its first-party serving.

### Nebius

Nebius is an Amsterdam-headquartered AI cloud and the strongest European alternative to the US hyperscalers. It sells raw NVIDIA GPU compute, from H100s at $2.15 an hour preemptible up to GB300 NVL72 racks, and it has begun adding Vera Rubin. Hyperscale buyers back it: a Microsoft capacity deal worth about $17.4B in September 2025, then a Meta agreement worth up to about $27B in March 2026.
