Aion 3.5 Mini is the lower-cost tier of AionLabs' Aion 3.5 generation, dated 23 September 2026 in this catalog alongside the flagship Aion 3.5. Rather than a single network, AionLabs describes a collaborative generation pipeline in which multiple specialized models each contribute to one response. The vendor's stated goal is stronger narrative structure and more compelling tension and conflict at lower cost. Because it is a multi-model system, no parameter count is published.

Compared with Aion 3.0 Mini from July 2026, the 3.5 mini is described as built on the GLM family — the same lineage associated with the 3.5 generation that also includes Aion 3.0. Its context window is listed at 262,144 tokens, which is the practical constraint for long-running roleplay sessions and serialized interactive fiction, where earlier chapters need to stay in view. AionLabs' public documentation presents the family as a model listing rather than a detailed technical report, so generation-over-generation changes beyond the stated base family and capability set are not spelled out in primary material.

Functionally, the model is positioned for mature and darker themes handled with nuance, and it supports tool calling, which lets an interactive-fiction front end expose dice rolls, inventory, state tracking or retrieval functions to the narrator. This catalog also lists reasoning and web search among its capabilities.

One caveat worth stating plainly: AionLabs publishes no benchmark table for Aion 3.5 Mini. For narrative work, evaluating it on your own scenes and prompts remains the practical approach.
