Use any model with Aider

Aider reads standard OpenAI environment variables, so CompanyFabric drops in with two exports. Pair a strong editor model with a cheap weak model for commit messages and repo maps.

Step by step

Setup

  1. 1

    Export the endpoint and key. Aider reads the OPENAI_* variables, these lines point them at your CompanyFabric key (no OpenAI account needed):

    export COMPANYFABRIC_API_KEY="sk-cf-…"
export OPENAI_API_BASE="https://api.companyfabric.com/v1"
export OPENAI_API_KEY="$COMPANYFABRIC_API_KEY"
  2. 2

    Run Aider with your model picks:

    aider --model openai/anthropic/claude-sonnet-5-5 \
      --weak-model openai/anthropic/claude-haiku-4-5

FAQ

Frequently asked questions

Why the double prefix in --model?

Aider namespaces providers; 'openai/' selects its OpenAI-compatible client, and the rest is the CompanyFabric catalog id passed through as the model string.
