Instantly via the EU router or as a dedicated GPU deployment. Data stays in Europe.
Qwen3.5 397B A17B is an open-source language model from Qwen3.5-397b-a17b with a 262K-token context window, hosted on EU GPUs via an OpenAI-compatible API.
This model needs 400 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.

}'Yes. HostYourAI runs Qwen3.5 397B A17B on GPUs in European datacenters via vLLM. Prompts and outputs never leave the EU and there is no US cloud provider in the chain.
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.
Via the shared EU router you pay €1.20 per million input tokens and €7.20 per million output tokens, with no fixed costs. For high volume or isolation you can also run Qwen3.5 397B A17B as a dedicated hourly GPU instance.
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.
