## Why Included

Vercel AI Gateway now serves the medical-focused Ling 3.0 Flash Sante free through October 4. Use its free-only model ID to prevent requests from converting to paid usage afterward.

## Source Summary

**Ling 3.0 Flash Sante** is available through Vercel AI Gateway free until **October 4**. The medical-focused MoE model has **124B total and about 5.1B active parameters per token**, a **256K context window**, and function calling.

## Practical Implication

For a bounded evaluation, use inclusionai/ling-3.0-flash-sante-free so traffic stops when the offer ends. The standard ID begins billing afterward; both IDs remain visible in spend tracking and traces during the free period.

## Agent-Ready Context

**Ling 3.0 Flash Sante** is available through Vercel AI Gateway free until **October 4**. The medical-focused MoE model has **124B total and about 5.1B active parameters per token**, a **256K context window**, and function calling.

For a bounded evaluation, use inclusionai/ling-3.0-flash-sante-free so traffic stops when the offer ends. The standard ID begins billing afterward; both IDs remain visible in spend tracking and traces during the free period.

The material describes intended medical and research workloads but gives no quality or safety evaluation. The free period is temporary, and only the free-specific ID prevents automatic paid continuation.

## Connected Context

Feed7 judgment across 691 accumulated Signals:

This adds a specialized medical evaluation route rather than another general coding default. Like the MiniMax promotion, the free-specific ID makes expiry behavior part of configuration: it stops traffic instead of silently continuing at paid rates. The 256K context and function calling define a testable workload envelope, but the absence of quality or safety evidence leaves medical suitability unresolved.

- [MiniMax M3 and M2.7 are free on AI Gateway](https://feed7.dev/p/minimax-m3-and-m2-7-are-free-on-ai-gateway-185wejm) — Both use expiring free-specific IDs that hard-stop after the promotion, reinforcing that temporary evaluations should be isolated from durable production routing.
- [Qwen 3.8 Max now available on Vercel AI Gateway](https://feed7.dev/p/qwen-3-8-max-now-available-on-vercel-ai-gateway-1ikih0e) — Qwen supplies a broader long-context multimodal route, while Ling narrows the evaluation target to medical and research workloads; neither provides comparative quality evidence.

## Context Map

## Uncertainty

- The material describes intended medical and research workloads but gives no quality or safety evaluation. The free period is temporary, and only the free-specific ID prevents automatic paid continuation.
