Shared EU router, pay-per-token, scale-to-zero. Dedicated GPU deployments are billed hourly, see pricing.
Bench is our quality index for every model, 0 to 100. It rests on public measurements (Epoch AI with about 40 benchmarks, LiveBench, LMArena and more) and is refreshed every morning. Where nobody measures, it shows an estimate with a range.
No public benchmark yet: estimated from size and release date.
Range 41.5 to 64.3

}'Yes. HostYourAI runs Apertus 70B Instruct 2509 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 €1.44 per million input tokens and €2.30 per million output tokens, with no fixed costs. For high volume or isolation you can also run Apertus 70B Instruct 2509 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.
