Aion Labs models

Aion 3.5 is the full-size roleplay system from AionLabs, with several models contributing to every reply. Give it a scenario, characters and the story so far, and it writes the next scene with firm structure and real conflict. It keeps about 260 pages in mind, twice as much as Aion 3.0, so long campaigns stay in view.

Aion 3.5 Mini keeps the method of Aion 3.5, with several models writing each reply together, in a smaller and cheaper build. Give it a scenario and the story so far, and the next scene comes back with its structure and conflict intact. It keeps about 260 pages in mind, so it also holds long campaigns.

Aion-3.0 is a roleplay and storytelling system in which several specialised models each write part of every reply. Give it the scenario and the story so far, and the next beat comes back with firmer structure and sharper tension than a single model gives. It keeps about 130 pages of story in mind.

Aion-2.0 is built for roleplay and interactive fiction. Give it a scenario, a character sheet and the conversation so far, and it carries the scene on, steering it toward crises, turning points and clashes and handling mature or dark themes with more depth. It keeps about 130 pages of the story in mind.

Roleplay and storytelling with stronger plot structure, tension and conflict

Aion-RP is a small model for character roleplay, built from a plain Llama 3.1 base rather than its instruction-tuned version, so its writing reads more natural and varied. Give it the character and the conversation, and it replies in character. It scored highest on the character part of the RPBench-Auto roleplay test.
