selectChatModelsAsync

Select chat models by a selector. This can yield multiple or no chat models and extensions must handle these cases, esp. when no chat model exists, gracefully.

const models = await vscode.lm.selectChatModels({ family: 'gpt-3.5-turbo' });
if (models.length > 0) {
	const [first] = models;
	const response = await first.sendRequest(...)
	// ...
} else {
	// NO chat models available
}

A selector can be written to broadly match all models of a given vendor or family, or it can narrowly select one model by ID. Keep in mind that the available set of models will change over time, but also that prompts may perform differently in different models.

Note that extensions can hold on to the results returned by this function and use them later. However, when the onDidChangeChatModels-event is fired the list of chat models might have changed and extensions should re-query.
