Quickstart

Set up DeepSeek in Aider

  1. 1

    Export the endpoint and key. Aider reads the OPENAI_* variables, the value is your CompanyFabric key (sk-cf-…), 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 on this model (the openai/ prefix selects Aider's OpenAI-compatible client; the rest is the catalog id):

    aider --model openai/deepseek/deepseek-v4-pro
