OpenAI Codex / ChatGPT

Configuration

Install OpenAI Codex / ChatGPT and Node.js 20 or later. Create an AudioLab workspace key with llm.write, available credits, and access to the selected model. Export it as AUDIOLAB_API_KEY in the terminal that launches the agent.

model = "gpt-5.3-codex"
model_provider = "audiolab"
web_search = "disabled"
model_reasoning_summary = "none"
model_reasoning_effort = "low"

[model_providers.audiolab]
name = "AudioLab"
base_url = "https://api.tryaudiolab.ai/v1"
env_key = "AUDIOLAB_API_KEY"
wire_api = "responses"
supports_websockets = false

[features]
multi_agent = false
multi_agent_v2 = false
image_generation = false

[tools]
view_image = false

Automatic Setup

The command previews the files and fields it changes. Confirm to apply; it stores a private backup and prints an undo command. It does not store the API key or change your shell profile. Automatic file setup supports macOS and Linux.

Launch

npx https://tryaudiolab.ai/cli/router-0.1.0.tgz run codex

Requires Codex 0.134 or later for separate profile files. This config connects local Codex to the Router API; it does not connect the hosted ChatGPT app or transfer subscription credits. Stateless text and client tools are supported; stored responses, hosted search, images, and remote compaction are not.

Supported Configuration

Use Codex 0.134 or later. The separate profile preserves your normal config and login. gpt-5.3-codex selects the reviewed native Responses path; choosing an arbitrary chat model is not equivalent. The profile disables hosted search, image generation, multi-agent namespaces, and WebSocket transport. Stateless text and client function/custom tools are supported. Stored responses, remote compaction, media input, hosted tools, and background requests are not. Codex 0.154 was checked against a local streaming fixture and Router validation. Start a new conversation before remote compaction is needed. ChatGPT subscription credits and the hosted ChatGPT app are separate from Router API access.

Verify the Connection

Send a short text prompt, then a read-only tool request in a disposable project. Check the model, request record, and usage in Router. Test streaming and a follow-up turn before using a longer workflow. Client-specific tools and permissions remain managed by OpenAI Codex / ChatGPT.

The setup command can check authentication and model discovery without generating a response. See the protocol contracts for model and feature limits.
