+3. MULTIPLE PROVIDERS                          *gp.nvim-3.-multiple-providers*
+
+The following LLM providers are currently supported besides OpenAI:
+
+- Ollama <https://github.com/ollama/ollama> for local/offline open-source models. The plugin assumes you have the Ollama service up and running with configured models available (the default Ollama agent uses Llama3).
+- GitHub Copilot <https://github.com/settings/copilot> with a Copilot license (zbirenbaum/copilot.lua <https://github.com/zbirenbaum/copilot.lua> or github/copilot.vim <https://github.com/github/copilot.vim> for autocomplete). You can access the underlying GPT-4 model without paying anything extra (essentially unlimited GPT-4 access).
+- Perplexity.ai <https://www.perplexity.ai/pro> Pro users have $5/month free API credits available (the default PPLX agent uses Mixtral-8x7b).
+- Anthropic <https://www.anthropic.com/api> to access Claude models, which currently outperform GPT-4 in some benchmarks.
+- Google Gemini <https://ai.google.dev/> with a quite generous free range but some geo-restrictions (EU).
+- Any other "OpenAI chat/completions" compatible endpoint (Azure, LM Studio, etc.)

+Below is an example of the relevant configuration part enabling some of these.
+The `secret` field has the same capabilities as `openai_api_key` (which is
+still supported for compatibility).

 The core plugin only needs `curl` installed to make calls to OpenAI API and
 `grep` for ChatFinder. So Linux, BSD and Mac OS should be covered.
