Manual setup

Install Codex CLI · Set your environment variables

After setting ZASHMODEL_API_KEY, merge these fields into your user-level ~/.codex/config.toml. Keep your other settings, avoid duplicate TOML keys and choose a model that supports Responses and the tools your task needs.

~/.codex/config.toml
model_provider = "zashmodel"
model = "YOUR_MODEL_ID"

[model_providers.zashmodel]
name = "Zashmodel"
base_url = "https://zashmodel.com/v1"
env_key = "ZASHMODEL_API_KEY"
wire_api = "responses"
requires_openai_auth = false

Start codex from the same terminal. This configuration reads the Zashmodel key from the environment; existing configurations using another credential source must be updated consistently.
