Model Card
Aion-3.0 is a multi-model roleplaying and storytelling system from AionLabs, built on the GLM family of models. Rather than a single model generating the full response, it runs a collaborative generation process in which multiple specialized models each contribute, aimed at producing stronger narrative structure and more compelling tension and conflict.
It handles mature and darker themes with notable nuance, continuing the roleplay and narrative focus of AionLabs' earlier Aion models such as Aion-2.0 and Aion-RP.
The model supports a 131K-token context window with up to 32K tokens of output. Aion-3.0 is a good fit for developers building interactive fiction, character-driven chat, or other creative-writing tools where narrative depth and thematic nuance matter more than raw speed.

Aion-3.0-Mini
Aion-3.0-Mini is a multi-model roleplaying and storytelling system from AionLabs, built on the DeepSeek family of models rather than the GLM base used in the full Aion-3.0. Like its larger sibling, it runs a collaborative generation process in which multiple specialized models each contribute to a response, aimed at producing stronger narrative structure and more compelling tension and conflict. It handles mature and darker themes with notable nuance, continuing the roleplay and narrative focus of AionLabs' earlier Aion models. The model supports a 131K-token context window with up to 32K tokens of output. Pricing is $0.70 per million input tokens and $1.40 per million output tokens, roughly a quarter of Aion-3.0's cost, making it a fit for developers who want the same collaborative-generation approach to character-driven chat and interactive fiction at a lower price point.
ChatAion-2.0
Aion 2.0 is a fine-tuned variant of DeepSeek V3.2, developed by AionLabs and optimized for immersive roleplaying and storytelling. It excels at generating narratives with natural tension, conflict, and dramatic stakes, and handles mature or darker themes with notable nuance. The model offers a 131K-token context window with up to 32K tokens of output, making it well-suited for long-form creative sessions. It supports function calling and streaming. On third-party benchmarks, it has scored 99.5% on general knowledge, 96% on mathematics, and 93.5% on coding tasks. Aion 2.0 is a strong pick for developers building interactive fiction, character-driven chat experiences, or creative writing tools where narrative depth and engagement matter more than raw speed.
ChatAion-RP 1.0 (8B)
Aion RP 1.0 8B is an uncensored roleplay and creative writing model from AionLabs, fine-tuned from the Llama 3.1 8B base model rather than an instruct variant. This base-model approach is designed to produce more natural and varied writing. It ranks highest in the character evaluation portion of RPBench-Auto, a roleplaying-specific benchmark derived from Arena-Hard-Auto where LLMs evaluate each other's responses. The model supports the full 131K context window and multi-turn conversations. Best suited for character-driven chat applications, interactive storytelling, and persona-consistent dialogue. A recommended temperature of 0.7 is advised, as higher values can degrade output quality.
