Bench index

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.

~46.9 / 100 · Estimate

No public benchmark yet: estimated from size and release date.

Specialised model (guard, OCR or captioning): the language score says little about its task.

Range 35.5 to 58.3

Frequently asked questions

Can I run granite guardian 4.1 8b in the EU?

Yes. HostYourAI runs granite guardian 4.1 8b 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 granite guardian 4.1 8b 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 granite guardian 4.1 8b cost?

granite guardian 4.1 8b is available on request: through the shared EU router after a quick chat, or as your own dedicated GPU deployment billed per hour. Tell us your use case and we will set it up for you.

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.
