How do I access Aion-RP 1.0 (8B) from inside Iran?

Is Aion-RP 1.0 (8B) compatible with the OpenAI SDK?

Yes. Hormouz exposes an OpenAI-compatible chat-completions API. Change the base URL to Hormouz and drop in your Hormouz key, and existing OpenAI SDK code runs unchanged.

Why is Aion-RP a base model rather than an instruct model?

It was deliberately fine-tuned from a base model to produce more natural, varied roleplay writing. Instruct models can feel stiffer in character; a tuned base can read more organically, which is why it tops the RPBench-Auto character evaluation.
