# OpenAI: o3 (batch)

[OpenRouter](/en/providers/openrouter/)

Last reviewed: 09 Oct 2026

## Sovereignty and hosting

This model is catalogued for reference. It is not hosted on LLM EU yet, and no first-party endpoint serves it here. Requests to it go to the provider directly, under that provider's own terms.

## Summary

Served through OpenRouter as openai/o3:batch. Runs outside the EU; the residency class on its endpoint says so.

### Verification status

Where a field has no source, the card shows it as unverified instead of filling it in. An empty field is information.

LLM EU Verified means documented, not legally certified. It is not an AI Act conformity assessment and LLM EU is not an EU body.
