Codex - AsterWise

Configuration

Set your key in the terminal:

export ASTER_API_KEY='your Aster API key'

Add the following to ~/.codex/config.toml, preserving any unrelated configuration:

model = "aster-code"
model_provider = "aster"
web_search = "disabled"

[features]
multi_agent = false

[model_providers.aster]
name = "Aster"
base_url = "https://api.asterwise.dev/v1"
env_key = "ASTER_API_KEY"
wire_api = "responses"

Start conservatively

Copy the context-window and output-limit values from the authenticated Setup page. Begin with web search and multi-agent operation disabled, then validate any additional Codex feature against your installed version before relying on it.
