llm -m gemini-2.0-flash-lite-preview-02-05 hi

Error: models/gemini-2.0-flash-lite-preview-02-05 is not found for API version v1beta, or is not supported for generateContent. Call ListModels to see the list of available models and their supported methods.

Looks like they've retired that alias!

I could set that up as a default alias but I think I'll let people who rely on that make the change themselves.

Hi there! How can I help you today?

llm -m gemini-2.0-flash-lite describe -a https://static.simonwillison.net/static/2024/pelicans.jpg

Here is a description of the image:

The image captures a large gathering of birds, predominantly pelicans, on a rocky, uneven surface. The pelicans, with their distinctive large beaks and plumage, are clustered closely together, intermingling with smaller, darker-colored birds. The rocky terrain appears to be near a body of water, as a calm, blue expanse is visible in the background. The lighting in the image suggests an overcast or slightly diffused daylight, casting a muted tone over the scene.
