ChatGPT Desktop

ChatGPT Desktop App (aka: Work \ Codex)

1. Download and Install the ChatGPT Desktop App
2. Select "Enter API Key"

   

3. Enter your API Key from UltimateAI (settings -> account)

   

4. Add a single line to the top of your config.toml (hint: file-> settings -> open config)

Add this these lines to the top of your "~/.codex/config.toml"

openai_base_url = "https://api.ultimateai.org/v1"
model_context_window = 250000
model_auto_compact_token_limit = 200000

Start a NEW chat\window.

Note: For the first message, there may be a few re-tries while the protocol is negotiated.

Troubleshooting: If you already had Codex configured with another provider and you were not prompted for an API key, also edit "~/.codex/auth.json" then restart.

{
  "auth_mode": "apikey",
  "OPENAI_API_KEY": "<your key>"
}
