I’m building a Cursor/VSCode extension that has a custom interface and I’m trying to hook into LLM support within cursor.

I’m using code like this in the extension host, and expecting to see some of the models from cursor. It works in VSCode, but I can’t seem to see any models available in Cursor (tried calling with no parameters as well.

```ts
async function checkForLM() {
  const models = await vscode.lm.selectChatModels({ family: "gpt-4o" });
  console.log("Found models", models);
  if (models.length > 0) {
    const [first] = models;
    const response = await first.sendRequest([
      { role: vscode.LanguageModelChatMessageRole.User, name: "user", content: [{ value: "Hello, how are you?" }] },
    ]);
    // ...
  } else {
    // NO chat models available
  }
}

```

FYI, I posted a [bug report](https://forum.cursor.com/t/vscode-language-model-api-support/44585) on this too. Hopefully that will get traction.

Have you found a solution yet?

Hey, we don’t currently expose any models out via that API yet, but I’ve logged this as something for the team to look into!

“currently”

When is that “exposure” supposed to get implemented?
