Ling 3.1 Flash is now available on AI Gateway
By Steven Van ·
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 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 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.
