Codex CLI

Codex CLI can be configured to use AI Bridge by setting up a custom model provider.

Configuration

To configure Codex CLI to use AI Bridge, set the following configuration options in your Codex configuration file (e.g., ~/.codex/config.toml):

model_provider = "aibridge"

[model_providers.aibridge]
name = "AI Bridge"
base_url = "<your-deployment-url>/api/v2/aibridge/openai/v1"
env_key = "OPENAI_API_KEY"
wire_api = "responses"

Run Codex as usual. It will automatically use the aibridge model provider from your configuration:

If configuring within a Coder workspace, you can also use the Codex CLI module and set the following variables:

module "codex" {
  source          = "registry.coder.com/coder-labs/codex/coder"
  version         = "~> 4.1"
  agent_id        = coder_agent.main.id
  workdir         = "/path/to/project"  # Set to your project directory
  enable_aibridge = true
}

Authentication

To authenticate with AI Bridge, get your Coder session token and set it in your environment:

export OPENAI_API_KEY="<your-coder-session-token>"
