All models in one place.

Yes. Bring your own Anthropic, OpenAI or Google keys and keep your existing provider relationship, rates and committed-spend discounts, or use Harriet managed credits for a single invoice with access to all the frontier labs as well as high-quality open-weight models. Either way the models are the same.

Claude, OpenAI and open models can all be hosted in the EU, and the EU-hosted tab lists which ones and what they cost there. Pick EU hosting per team, or use the same models in the US.

Claude, hosted in the EU or the US, and every open model on the router. Zero data retention is available on request and agreed during rollout. Claude Fable 5 is not covered, because Anthropic keeps it outside zero data retention.

It is a setting on the team profile. Change the default model and it applies to everyone in that team on their next request. No reinstall, no retraining, no migration.

Tell us which one. The router is built to add providers and models as they ship, and this roster moves often; the date under the catalog says how current it is.
