Aion-3.0-Mini API on ModelFold
Aion-3.0 Mini is a multi-model roleplaying and storytelling system from AionLabs built on the DeepSeek family, with multiple specialized models collaborating on each response.

Use it without hosting anything

Core Capabilities of Aion-3.0-Mini
Up to 131K tokens of context
Keep long conversations, large documents and sizeable code in a single request, so the model can reason over the full material instead of fragments.
Function calling
Aion-3.0-Mini supports tool (function) calling: describe your functions in the request and the model returns structured calls your code can run — the basis for agents and integrations.
Reasoning mode
Aion-3.0-Mini can produce reasoning before its final answer; in the Playground you can switch reasoning on or off to compare results.
Structured outputs
Ask for JSON that follows a schema (response_format), which makes extraction, classification and system integrations more reliable.
