## What changed

- Prose text, headings, titles, and descriptions updated across all docs
- Directories renamed:
  - `docs/ai-coder/ai-bridge/` → `docs/ai-coder/ai-gateway/`
- `docs/ai-coder/ai-bridge/ai-bridge-proxy/` →
`docs/ai-coder/ai-gateway/ai-gateway-proxy/`
  - `docs/ai-coder/agent-boundaries/` → `docs/ai-coder/agent-firewall/`
- All internal markdown links updated to new paths

- Rename notice added to AI Gateway and Agent Firewall entrypoint pages

## Companion PR

URL redirects (old paths → new paths):
[coder/coder.com#700](https://github.com/coder/coder.com/pull/700)

## What is intentionally NOT changed

- **Env vars**: `CODER_AIBRIDGE_*`
- **CLI flags**: `--aibridge-*`
- **API paths**: `/api/v2/aibridge/*`
- **Config keys**: `aibridge:` YAML blocks
- **Terraform variables**: `enable_aibridge`, `boundary_version`,
`use_boundary_directly`
- **Process names**: `aibridged`, `aibridgeproxyd`
- **Prometheus metrics**: `coder_aibridged_*`, `coder_aibridgeproxyd_*`
- **SDK types**: `codersdk.AIBridge*`
- **GitHub URLs**: `github.com/coder/aibridge`
- **Image paths**: `images/aibridge/`
- **Auto-generated reference docs**: `docs/reference/cli/aibridge*.md`,
`docs/reference/api/aibridge.md`, `docs/reference/api/schemas.md`
- **Frontend code**: `site/src/` references (separate PR)

Code-level renames (env vars, configs, frontend) are planned for a
follow-up PR.

# Codex CLI
Codex CLI can be configured to use AI Gateway by setting up a custom model provider.
## Centralized API Key
To configure Codex CLI to use AI Gateway, set the following configuration options in your Codex configuration file (e.g., `~/.codex/config.toml`):
```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"
```
To authenticate with AI Gateway, get your **[Coder session token](../../../admin/users/sessions-tokens.md#generate-a-long-lived-api-token-on-behalf-of-yourself)** and set it in your environment:
```bash
export OPENAI_API_KEY="<your-coder-session-token>"
```
Run Codex as usual. It will automatically use the `aibridge` model provider from your configuration.
## BYOK (Personal API Key)
Add the following to your Codex configuration file (e.g., `~/.codex/config.toml`):
```toml
model_provider = "aibridge"
[model_providers.aibridge]
name = "AI Bridge"
base_url = "<your-deployment-url>/api/v2/aibridge/openai/v1"
wire_api = "responses"
requires_openai_auth = true
env_http_headers = { "X-Coder-AI-Governance-Token" = "CODER_SESSION_TOKEN" }
```
Set both environment variables:
```bash
# Your personal OpenAI API key, forwarded to OpenAI.
export OPENAI_API_KEY="<your-openai-api-key>"
# Your Coder session token, used for authentication with AI Gateway.
export CODER_SESSION_TOKEN="<your-coder-session-token>"
```
## BYOK (ChatGPT Subscription)
Add the following to your Codex configuration file (e.g., `~/.codex/config.toml`):
```toml
model_provider = "aibridge"
[model_providers.aibridge]
name = "AI Bridge"
base_url = "<your-deployment-url>/api/v2/aibridge/chatgpt/v1"
wire_api = "responses"
requires_openai_auth = true
env_http_headers = { "X-Coder-AI-Governance-Token" = "CODER_SESSION_TOKEN" }
```
> [!NOTE]
> The `base_url` uses `/aibridge/chatgpt/v1` instead of `/aibridge/openai/v1` to route requests through the ChatGPT provider.
Set your Coder session token and ensure `OPENAI_API_KEY` is not set:
```bash
# Your Coder session token, used for authentication with AI Gateway.
export CODER_SESSION_TOKEN="<your-coder-session-token>"
# Ensure no OpenAI API key is set so Codex uses ChatGPT login instead.
unset OPENAI_API_KEY
```
When you run Codex, it will prompt you to log in with your ChatGPT account.
## Pre-configuring in Templates
If configuring within a Coder workspace, you can use the
[Codex CLI](https://registry.coder.com/modules/coder-labs/codex) module:
```tf
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
}
```
