## How they compare

Nebius Token Factory serves 60+ open models, including DeepSeek V4 Pro, Kimi K3 and MiniMax M3, from $0.06 per million input tokens behind an OpenAI compatible API. Dedicated endpoints carry a 99.9% SLA with speculative decoding and EU or US placement, uploaded fine-tunes serve at token prices, and raw GPUs sit on the same account. There is no free trial and a $25 minimum first payment. Boundless lists 22 models, including DeepSeek V4 Pro at $1.04 in and $2.08 out, Kimi K3 at $2.30 in and $11.40 out and MiniMax M3 at $0.28 in and $1.10 out, plus resold GPT and Claude. It runs in the US or Europe with zero data retention, starts accounts with free credits and offers no fine-tuning.

Nebius is the pick for European buyers who want a broad catalog, their own fine-tunes in production and a path from tokens to training on raw GPUs. Boundless fits teams that want GPT and Claude beside open models on one OpenAI and Anthropic compatible API, or a reserved deployment where its engineers pick the model on your evals and tune it against contract targets.

## What each one does

### 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.

### Boundless

Boundless launched in September 2026 as an inference partner for AI-native startups. It sells two things. The Model API serves pre-tuned models on shared capacity, billed per token from prepaid credits with a budget per API key. Tailored inference reserves capacity for one customer, and Boundless engineers pick the model on the customer’s own evals, tune precision, batching, caching, speculative decoding and parallelism, then run the deployment against uptime, throughput and latency targets written into the contract. A free two-week evaluation tests those targets on real traffic against the customer’s current provider first.
