List of Aion Labs Models
Aion-2.0
aion-labs/aion-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-1.0
aion-labs/aion-1.0
Aion 1.0 is AionLabs' most powerful reasoning model, a multi-model system built on DeepSeek-R1 and augmented with Tree of Thoughts (ToT) and Mixture of Experts (MoE) techniques. It supports a 131K context window with up to 32K output tokens and includes vision capabilities. The model excels at reasoning and coding tasks, scoring 96.0% on coding, 99.5% on general knowledge, and achieving perfect accuracy on reasoning and email classification benchmarks (Benchable). It also ranks among the fastest models at its price point. Best suited for developers who need strong reasoning, coding assistance, and classification at competitive throughput.
ChatAion-1.0-Mini
aion-labs/aion-1.0-mini
Aion 1.0 Mini is a 32B-parameter reasoning model from AionLabs, distilled from DeepSeek-R1 and based on a modified FuseAI variant. It is designed for strong performance in mathematics, coding, and logic at a fraction of the cost of full-scale models. It delivers standout speed and pricing, consistently ranking among the fastest and most affordable options available. On Benchable, it scored 99.0% on email classification and 82.0% on reasoning tasks. This model is a good fit for developers who need fast, budget-friendly reasoning for structured tasks and can work around its instruction-following limitations.
ChatAion-RP 1.0 (8B)
aion-labs/aion-rp-llama-3.1-8b
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.
