[Ling 3.0 Flash Fin from Inclusion AI](https://vercel.com/ai-gateway/models/ling-3.0-flash-fin) 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](https://vercel.com/ai-gateway/models/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.

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](https://vercel.com/docs/ai-gateway/coding-agents), 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](https://vercel.com/ai-gateway/models/ling-3.0-flash-fin).
