Ling 3.0 Tiny API on ModelFold
Ling 3.0 Tiny is a Mixture-of-Experts model from inclusionAI with 1.3B active parameters out of 7.9B total, designed for responsive agents, instruction following and multi-turn conversations.

What Is the Ling 3.0 Tiny API
Ling 3.0 Tiny at a glance
Ling 3.0 Tiny is a chat model from inclusionAI. It accepts text as input and returns text, with a context window of up to 262K tokens.
Use it without hosting anything
On ModelFold you call Ling 3.0 Tiny with a single API key — no model weights to download and no inference servers to run. The same key also works for the other chat, image, video and audio models on ModelFold.
Core Capabilities of Ling 3.0 Tiny
Up to 262K 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
Ling 3.0 Tiny 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
Ling 3.0 Tiny 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.
