Plugin Overview

The plugin uses adapters to connect to LLMs. Out of the box, the plugin supports:

• Anthropic (anthropic) - Requires an API key and supports prompt caching
• Copilot (copilot) - Requires a token which is created via :Copilot setup in Copilot.vim
• GitHub Models (githubmodels) - Requires gh to be installed and logged in
• DeepSeek (deepseek) - Requires an API key
• Gemini (gemini) - Requires an API key
• HuggingFace (huggingface) - Requires an API key
• Mistral AI (mistral) - Requires an API key
• Novita (novita) - Requires an API key
• Ollama (ollama) - Both local and remotely hosted
• OpenAI (openai) - Requires an API key
• Azure OpenAI (azure_openai) - Requires an Azure OpenAI service with a model deployment
• xAI (xai) - Requires an API key

The plugin utilises objects called strategies. These are the different ways that a user can interact with the plugin. The chat strategy harnesses a buffer to allow direct conversation with the LLM. The inline strategy allows for output from the LLM to be written directly into a pre-existing Neovim buffer.

The plugin allows you to specify adapters for each strategy and also for each prompt library entry.
