- Vercel added InclusionAI's Ling 3.1 Flash 1019 to AI Gateway, free until November 3, 2026.
- The model is designed for coding, multi-step reasoning and tool-using agents, with a 1M-token context window.
- Model name: inclusionai/ling-3.1-flash-1019, usable via AI SDK and Chat Completions.
- From November 3, requests are charged at the published rate.
- Vercel says AI Gateway adds no markup and no platform fee on inference, including BYOK.
What the model offers
Ling 3.1 Flash 1019 is an updated model from InclusionAI. Vercel says it targets three areas: coding, multi-step reasoning, and agents that call tools. It also has a 1M-token context window, which according to Vercel supports workflows involving long documents, code and extended task histories.
Developers call it with the model name inclusionai/ling-3.1-flash-1019. Vercel's example uses the AI SDK and its streamText function, passing that model name along with a prompt asking for three ways to make an AI agent more reliable. The changelog also lists Chat Completions as a supported way to call the model.
Free access and what happens next
The model is free on AI Gateway until November 3, 2026. Vercel states that free requests still appear in the spend dashboard with a full request trace, they simply cost nothing. On November 3, requests begin charging at the published rate. The changelog does not state that rate in the text provided.
Because the free period is time-limited, teams testing the model on long-context or agent workloads have a fixed window to evaluate it without cost. After that date, usage is billed.
Use in coding agents and the playground
Vercel says the model can be used in coding agents including Claude Code, Codex and Cursor. The setup steps are:
- Install the latest Vercel CLI.
- Run npx vercel ai-gateway setup.
- Select inclusionai/ling-3.1-flash-1019 in the agent.
Vercel points to its coding agents guide for details. The model can also be tried in the AI Gateway model playground.
About AI Gateway
AI Gateway is Vercel's unified API for calling models, tracking usage and cost, and configuring retries, failover and performance optimizations. Vercel says these are meant to deliver higher-than-provider uptime. The service includes custom reporting, Zero Data Retention support, budgets for API keys and routing rules.
On pricing, Vercel says AI Gateway reflects provider pricing with no markup and does not charge a platform fee on inference. That includes Bring Your Own Key (BYOK) requests.
What it means for developers
For developers already routing models through AI Gateway, the addition gives another option for agent and coding work with a large context window, accessible through the same API and tooling. The free period lets them test it before paid billing starts, and the no-markup policy means the later cost follows the provider's published pricing, according to Vercel.
