There's a lot of plugins/IDEs for assistant style LLMs, but the only TAB style autocompletion ones I know of are either proprietary (Github Copilot), or you need to get an API key (Codestral). If anyone knows of a local autocomplete model I'd love to hear about it.

The Continue extension (Jetbrains, VSCodium) lets you set up assistant and autocompletion independently with different API keys.
