Your own vLLM instance on European cloud (969 GB VRAM), billed hourly.

This model needs 969 GB of VRAM, so several GPUs. On the shared router you pay per token, with no fixed cost. You choose a dedicated deployment for guaranteed capacity, isolation and predictable cost. On price alone, a model this size breaks even in the order of billions of tokens a month. Want it worked out for your own volume? Mail info@hostyourai.com.

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

Frequently asked questions

Can I run Qwen3.5 397B A17B in the EU?

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.

Is hosting Qwen3.5 397B A17B 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 Qwen3.5 397B A17B cost?

Via the shared EU router you pay €0.69 per million input tokens and €4.14 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.

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.

Qwen3 ASR 0.6B hf

The Qwen3-ASR family includes Qwen3-ASR-1.7B and Qwen3-ASR-0.6B, which support language identification and ASR for 52 languages and dialects. Both leverage large-scale speech training data and the strong audio understanding capability of their foundation model, Qwen3-Omni. The 1.7B version achieves state-of-the-art performance among open-source ASR models and is competitive with the strongest proprietary commercial APIs.

[!Note] This repository contains model weights and configuration files for the pre-trained only model in the Hugging Face Transformers format. These artifacts are compatible with Hugging Face Transformers, vLLM, SGLang, etc. The intended use cases are fine-tuning, in-context learning experiments, and other research or development purposes, not direct interaction. However, the control tokens, e.g., <|imstart| and <|imend| were trained to allow efficient LoRA-style PEFT with the official chat template, mitigating the need to finetune embeddings, a significant optimization given Qwen3.5's larger
