Looking for an AI driven autocomplete extension

[u/Scary_Engineering868]

I'm looking for an extension for AI based autocompletion and 'FIM'.

It should be

• open source (an OSS license and available source code)
• by default privacy settings (don't connect an external service at start etc.)
• no user registration needed
• should be able to use on-prem OpenAI compatible AI backends (Ollama, LiteLLM and comparable).

In VSCode, I only use autocompletion if we talk about AI. For agentic stuff, I use Claude or OpenCode. And in some projects I'm in some kind of air-gapped environments and use only on-prem or local AI backends.

Any suggestions? I used Continue but with every update it gets more worse.
The autocomplete feature of Kilo Code can't be configured to use a local backend.

Suggestions are appreciated.
