You can launch a Lambda Cloud GPU instance and use SSH to log in, which offers benefits such as copying files from your local machine and using a local terminal. To spin up an instance, you'll need to add an SSH key if you don't already have one. If you do have an existing key, you can use it by copying the public key into the text field on the dashboard. Alternatively, you can create a new key locally using `ssh-keygen` or let Lambda Cloud create one for you. You'll also need to set up your local SSH directory and move the downloaded key into it with proper permissions. Once everything is set up, you can spin up an instance and log in using the SSH command. Note that instances are billed by the hour and do not offer persistent storage, so any data will be deleted when the instance is terminated.
