Aion Labs🇵🇱
aion-labs/aion-3.5Aion 3.5 is AionLabs' multi-model roleplaying and storytelling system built on the GLM family (262K-token context, released September 23, 2026), in which several specialized models each contribute to every response. It succeeds Aion-3.0 and is tuned for character-driven fiction with stronger narrative structure, tension, and conflict, rather than coding or general assistant work.
