Aion 3.0
AionLabs' multi-model collaborative text system for roleplaying and storytelling, built on GLM with tool use and reasoning.
Overview
What is Aion 3.0
Aion 3.0 is a proprietary multi-model collaborative text system from AionLabs, released in July 2026. Built on the GLM family, it specializes in roleplaying and storytelling through collaborative generation, offering tool use, reasoning, web search, and a 128K context window on Venice.
Running it privately on Venice
On Venice, Aion 3.0 runs with zero retention — your prompts are not stored, profiled, or used for training, giving you sovereignty over your creative sessions. You get the full multi-model collaborative experience with tool use, reasoning, and web search, billed per token without a subscription. Unlike open-source alternatives, the weights are closed, so you trade permissionless self-hosting for a specialized narrative engine.
Assessment
Strengths and limitations
- Multi-model collaborative generation designed for roleplaying and storytelling, producing stronger narrative structure and tension.
- Supports advanced capabilities on Venice: tool use / function calling, reasoning, web search, and structured JSON output.
- Specialized for creative writing and narrative scenarios rather than general chat.
- Competitive input pricing for a proprietary multi-model system.
- Closed weights: not open-source and cannot be self-hosted or fine-tuned.
- Output pricing ($7.50/1M tokens) is higher than many open-weight rivals, including the GLM family it builds on.
- Not uncensored: standard content moderation policies apply.
- Multi-model inference can introduce higher latency than single-model endpoints.

Use cases
What it is good for
- 01Roleplaying games and interactive fiction with deep narrative arcs.
- 02Collaborative storytelling and creative writing assistance.
- 03Character-driven dialogue generation with long-term memory across extended sessions.
- 04Agentic workflows that combine reasoning, tool use, and web search for research-heavy narratives.
- 05Structured output for game state, character sheets, and narrative JSON.
Prompting
Getting better results
Frame prompts as narrative scenes with explicit character motivations to leverage the collaborative tension engine.
Use the reasoning and tool-use capabilities for fact-checking lore or retrieving real-world references via web search.
Request structured JSON output for game state tracking or character profiles.
Iterate on multi-turn conversations to let the model build continuity across long sessions.

FAQ
Frequently asked questions
Aion 3.0 is a proprietary multi-model collaborative text system from AionLabs, released in July 2026. Built on the GLM family, it specializes in roleplaying and storytelling through collaborative generation, and supports tool use, reasoning, web search, and structured output on Venice.
Venice bills Aion 3.0 at $3.75 per 1M input tokens and $7.50 per 1M output tokens, with cached input at $0.94 per 1M. There is no subscription; you pay per token with credits.
No. Aion 3.0 is closed and proprietary. The weights are not available for download, so you cannot self-host or fine-tune it. If you need open-source alternatives, DeepSeek V3.2 or GLM 5.1 on Venice are fully open-weight options.
Choose Aion 3.0 for collaborative storytelling and narrative depth. Choose Claude Sonnet 4.6 for general-purpose reasoning and a 1M context window, though its output pricing is much higher.
Yes. On Venice, Aion 3.0 supports function calling / tool use, reasoning, web search, and structured JSON output, making it suitable for agentic workflows and research-assisted storytelling.
No. Aion 3.0 is not uncensored. Standard content moderation policies apply, so it may refuse certain requests just like other moderated models on Venice.
It runs under Venice's anonymized privacy tier with zero retention — your prompts are not stored, profiled, or used for training. However, it does not run inside a TEE or use end-to-end encryption.
Yes. You can request structured JSON schema output from Aion 3.0 on Venice, which is useful for game state, character sheets, and other structured narrative data.
Unlike a single GLM endpoint, Aion 3.0 uses multiple specialized models working collaboratively to generate responses, which AionLabs claims produces stronger narrative structure and more compelling tension.
