this plugin is designed specifically for the llama.cpp server api, if you want copilot like features with ollama, you can use an ollama instance as a drop-in replacement for github copilot with this plugin: https://github.com/bernardo-bruning/ollama-copilot
There is also https://github.com/olimorris/codecompanion.nvim which doesn't have text completion, but supports a lot of other AI editor workflows that I believe are inspired by Zed and supports ollama out of the box
