> ## Aion 3.0 API
>
> Aion 3.0 is a large language model by Aion Labs, available on the Venice API as `aion-labs-aion-3-0`. Requests are anonymized, so the provider never sees your identity.
>
> Aion 3.0 is a multi-model roleplaying and storytelling system from AionLabs, built on the GLM family of models. Multiple specialized models collaborate on each response to produce stronger narrative structure and more compelling tension and conflict. It handles mature and darker themes with nuance and supports tool calling for richer interactive fiction.
