Convex Agent SDK does not support LanguageModelV2 (e.g. Google Gemini)

[Mehtari-Nadir]

I'm trying to create an agent using (gemini-1.5-flash) as the chat model. However, I get a TypeScript error because the model returned by google.chat is a LanguageModelV2, while Convex Agent expects a LanguageModelV1.

`import { Agent } from "@convex-dev/agent";
import { components } from "../_generated/api";
import { google } from "@ai-sdk/google";

export const chatAgent = new Agent(components.agent, {
name: "human-resources-agent",
chat: google.chat("gemini-1.5-flash"), // ❌ Type error here
instructions: "You are a helpful assistant.",
});
`

Error Message:
Property 'defaultObjectGenerationMode' is missing in type 'LanguageModelV2' but required in type 'LanguageModelV1'.

Environment
"@ai-sdk/google": "^2.0.3",
"@convex-dev/agent": "^0.1.17",
Node.js version: v22.16.0
"typescript": "~5.8.3",

Use the alpha release - the v5 support is being worked on in this branch / PR: #93

@ianmacartney, do you mean installing it with npm i https://pkg.pr.new/get-convex/agent/@convex-dev/agent@93?
Because npm i @convex-dev/agent@alpha installs https://www.npmjs.com/package/@convex-dev/agent/v/0.1.18-alpha.1 that is still using ai v4.

yes, sorry for the confusion! edit: alpha now targets v5 as well
