# Ling 3.1 Flash is now available on AI Gateway

By Steven Van · 2026-09-30

Ling 3.1 Flash is free on AI Gateway until October 13, 2026, with a 262K-token context window and a free-only model ID that stops serving afterwards.

[Vercel](<https://creatorstoolbox.com/tools/vercel>) has added Ling 3.1 Flash from InclusionAI to AI Gateway, and the model is free to use through October 13, 2026. It is a hybrid reasoning language model with 560B total parameters and 25B active per token, and a 262K-token context window on AI Gateway. It is [designed for](<https://vercel.com/docs/ai-gateway/coding-agents>) coding, multi-step analysis, and agents that use tools, including workflows with long documents, code and extended task histories.

There are two model IDs, and they behave differently when the promotion ends:

- **inclusionai/ling-3.1-flash** is free during the promotion and begins billing when it ends.

- **inclusionai/ling-3.1-flash-free** stops serving when the promotion ends instead of billing.

To use it in a coding agent, follow the AI Gateway coding agents guide and select inclusionai/ling-3.1-flash as the model. It can also be tried in the AI Gateway model playground.
