# ~/.codex/config.toml
model = "YOUR_MODEL_ID"                  # any model id from the /models page
model_provider = "luxechain"

[model_providers.luxechain]
name = "luxechain"
base_url = "https://api.luxechain.si/v1"
env_key = "LUXECHAIN_API_KEY"
wire_api = "responses"      # Codex speaks the Responses API only

Codex only speaks the Responses API. wire_api must be "responses"; the old "chat" value is no longer accepted.
