[Ling 3.0 Flash Sante from inclusionAI](https://vercel.com/ai-gateway/models/ling-3.0-flash-sante) is now available on AI Gateway, free to use through October 4.

Ling 3.0 Flash Sante is a health and medicine-focused version of [Ling 3.0 Flash](https://vercel.com/ai-gateway/models/ling-3.0-flash). It is a Mixture-of-Experts model with 124B total parameters and about 5.1B active per token, a 256K token context window, and function calling.

The model is built for medical reasoning, professional healthcare tasks, deep research, evidence-based retrieval, and multi-step medical workflows. It retains the base model's general reasoning, coding, and agentic capabilities.

The standard model ID, `inclusionai/ling-3.0-flash-sante`, is free through October 4 and begins billing when the offer ends.

The free model ID, `inclusionai/ling-3.0-flash-sante-free`, stops serving when the offer ends instead of billing.

Free requests still appear in your spend dashboard and carry a trace, they just cost nothing.

To use Ling 3.0 Flash Sante, set `model` in the [AI SDK](https://ai-sdk.dev/):

Use `inclusionai/ling-3.0-flash-sante-free` if you want the model to stop serving when the offer ends rather than start billing.
