OpenAI-Compatible API

This provider works with any API that follows OpenAI's chat completions format: which includes OpenAI itself, many local model servers like Ollama, and a lot of third-party model APIs.

Setup

1. Open Settings → AI Providers
2. Find OpenAI-compatible API and click Configure
3. Enter:
   • API URL: the base URL of the endpoint
   • API Key: your API key (or any string if the server doesn't require one)
   • Model: the model name to use
4. Click Save

Common setups

OpenAI

• API URL: https://api.openai.com/v1
• API Key: your OpenAI key from platform.openai.com
• Model: gpt-4o or gpt-4o-mini

Ollama (local)

Run models locally with no API key and no data leaving your machine.

1. Install Ollama and pull a model: ollama pull llama3.2
2. In Coeus:
   • API URL: http://localhost:11434/v1
   • API Key: ollama (any string works)
   • Model: llama3.2

Other providers

Any provider with an OpenAI-compatible endpoint works the same way: Groq, Together AI, Mistral (with their compatibility layer), etc. Check their docs for the base URL.

Choosing a model

For answering questions about your notes, a mid-size model (GPT-4o-mini, Llama 3.2, Mistral 7B) works well and is fast and cheap. You only need a larger model for long, involved questions.

Attachments

Image attachments work if the model supports vision (like GPT-4o). Text-based models will skip image content.
