AionLabs: Aion-3.0

AionLabs: Aion-3.0 is a text model from AionLabs. It is a multi-model roleplaying and storytelling system built on the GLM family of models, and it uses a collaborative generation process in which multiple specialized models each contribute to the output. That design means the model is not a single monolithic network but a coordinated set of components, which is worth keeping in mind when you think about how it behaves in production.

The model works with text input and produces text output. It has a context window of 131072 tokens, which is large enough to hold long conversations, extended narrative passages or sizeable reference documents alongside your instructions. The maximum output is 32768 tokens, so responses can be long when you need them to be, though you can of course cap them yourself per request.

Because Aion-3.0 is built for roleplaying and storytelling, the obvious uses follow from that: character driven chat, interactive fiction, long form narrative drafting, world building with persistent context, and conversational agents that need to stay in persona across many turns. The collaborative generation approach is aimed at story and dialogue quality rather than at narrow classification or extraction tasks, so treat it as a general purpose text generator with a strong leaning toward creative and conversational work.

You call it through api14's OpenAI-compatible API using the model id "aion-labs/aion-3.0", so existing OpenAI SDKs and clients work with only the base URL and key changed. The supported request parameters are include_reasoning, max_tokens, reasoning, response_format, temperature, tool_choice, tools and top_p. That combination covers sampling control, output length, structured output via response_format, and function calling via tools with tool_choice, plus explicit switches for reasoning behaviour.

If your task is purely deterministic extraction, classification or strict format conversion with no conversational element, a smaller general purpose model may be simpler and cheaper to operate. Aion-3.0 is at its most useful when the job involves sustained dialogue, character consistency or narrative generation over long inputs.
