Dedicated deployment, from 250 GB of VRAM. Billed per GPU-hour.

This model needs 250 GB of VRAM, so several GPUs. That makes the shared router rate high. From roughly 50 million tokens a month a dedicated deployment costs less.

Shared EU router, pay-per-token, scale-to-zero. Dedicated GPU deployments are billed hourly, see pricing.

Frequently asked questions

Can I run Devstral 2 123B in the EU?

Yes. HostYourAI runs Devstral 2 123B on GPUs in European datacenters via vLLM. Prompts and outputs never leave the EU and there is no US cloud provider in the chain.

Is hosting Devstral 2 123B GDPR-compliant?

Yes. All processing happens inside the EU, a Data Processing Agreement (DPA) is available and the subprocessor list is public. Open-source weights also mean: no training on your data.

How much does Devstral 2 123B cost?

Via the shared EU router you pay €0.80 per million input tokens and €4.00 per million output tokens, with no fixed costs. For high volume or isolation you can also run Devstral 2 123B as a dedicated hourly GPU instance.

Is the API OpenAI-compatible?

Yes. You use the standard OpenAI SDKs with a custom base URL (https://hostyourai.com/api/v1). The Anthropic Messages API is supported as a drop-in as well.
