Vercel added Gemini 3.8 Flash to AI Gateway under the model identifier google/gemini-3.8-flash. Its release note describes text, image, PDF and video inputs, with text output and support for tool calls. This gives applications using the gateway a model option for analyzing supplied media and then responding or requesting a tool action.
The release also documents connecting coding agents through the gateway and selecting this model there. The concrete change is that the model can be selected by its identifier, including from connected coding agents.
