Vercel Ling 3.0 Flash Fin now available on AI Gateway for free release notes

Ling 3.0 Flash Fin from Inclusion AI is now available on AI Gateway, free to use through September 25.

Ling 3.0 Flash Fin is a finance-focused version of Ling 3.0 Flash. It has a 256K token context window, produces up to 32K output tokens, and supports reasoning and function calling.

The model is built for financial research, analysis, and multi-step tasks that run across many tool calls before producing an answer.

How to use the model during the offer period

Using the standard model name (i.e., inclusionai/ling-3.0-flash-fin) is free, but will automatically begin billing when the offer period ends.
To ensure you aren't billed after the free period, add the -free suffix to the standard name, and the model will stop serving when the offer ends (i.e., inclusionai/ling-3.0-flash-fin-free).

To use it in a coding agent, see the coding agents guide, then run vercel ai-gateway coding-agents setup to connect agents like Claude Code, Codex, OpenCode, Cursor, Pi, and more and select inclusionai/ling-3.0-flash-fin inside the agent.

Try Ling 3.0 Flash Fin in the model playground.
