About Aion-2.0

Aion-2.0 is an older roleplay model from AionLabs, built on DeepSeek V3.2 and tuned toward interactive fiction with more conflict and darker themes than a general assistant would write. It suits character chat and story collaboration. Tool calling works, though most people use it for plain conversation. The newer Aion 3.x models moved to GLM and DeepSeek bases with more attention to narrative structure.
