OpenClaw ChatGPT Subscription: Full Setup Guide
If you have been running OpenClaw on per-token API billing, there is a better way, and OpenAI has officially made it possible.
Two things happened that changed the OpenClaw subscription landscape. Anthropic confirmed that Claude subscriptions cannot be used with OpenClaw under their terms of service. And OpenAI (with Sam Altman on record and OpenClaw founder Peter Steinberger announcing on Twitter) confirmed that ChatGPT subscriptions can be used with OpenClaw. No API key billing. Just your flat monthly subscription.
This guide walks you through exactly how to connect your ChatGPT Plus or ChatGPT Pro subscription to OpenClaw, set GPT-5.3 Codex as your default model, and verify everything is working. We will also cover the self-surgery rule that every OpenClaw user needs to know before touching any config.
“OpenAI officially confirmed that ChatGPT subscriptions can power OpenClaw. That changes the cost equation entirely.”
Why OpenAI Is Now the Best Subscription Option for OpenClaw
For a while, Claude Code was the go-to subscription choice for OpenClaw users. Then Anthropic clarified their terms of service: using a Claude subscription to power OpenClaw falls outside what is permitted. Practically speaking, that means Claude subscription users risk losing access, and there is no official green light to run it that way.
OpenAI went the opposite direction. ChatGPT subscriptions are explicitly supported. The authentication flow is built into OpenClaw's onboarding wizard. The OpenClaw documentation confirms it: "OpenClaw fully supports OpenAI Codex subscription OAuth. The onboarding wizard can run the OAuth flow for you." This is not a workaround. It is the intended path.
The model at the center of this setup is GPT-5.3 Codex. OpenAI describes it as "the most capable agentic coding model to date," combining frontier coding performance with the reasoning and professional knowledge capabilities of GPT-5.2. For an AI assistant handling automations, workflows, and real business tasks inside OpenClaw, that is exactly the horsepower you want.
The cost structure makes it even cleaner. ChatGPT Plus is $20 per month. ChatGPT Pro is $200 per month. Both include Codex usage. Compare that to unpredictable per-token API billing on heavy usage months, and the math typically favors a flat subscription.
If you were previously running on a Claude subscription, this also works as a migration path. You can onboard OpenAI Codex and set it as your primary model without losing your existing OpenClaw configuration.
“Flat monthly pricing, official support, and OpenAI's most capable agentic model. This is now the cleaner stack.”
What You Need Before You Start
Before you run the onboarding command, make sure you have the following:
An active ChatGPT Plus ($20/month) or ChatGPT Pro ($200/month) subscription. You can check OpenAI's pricing page to confirm which plan fits your usage.
OpenClaw installed and the gateway running on your machine. If you have not set that up yet, start at the OpenClaw GitHub repository for the full installation guide.
Terminal access on your machine (Mac Terminal, Linux shell, or Windows WSL).
A browser available to complete the OAuth login step.
You do not need to touch your existing OpenClaw config before starting. The onboarding wizard handles that during the process. If you already have a working OpenClaw setup with another provider, you will keep those settings intact.
Step 1: Connect OpenAI to OpenClaw
Open Terminal on your machine and run:
openclaw onboard --auth-choice openai-codexThe onboarding wizard will walk you through a short sequence of prompts:
Accept the risk acknowledgment when prompted.
Choose Quick Start.
When asked about your existing config values, keep them as-is. Do not reset.
A browser window will open automatically. Log into your ChatGPT or OpenAI account and authorize Codex.
You will see "Authentication successful" in the browser. Return to your terminal.
That is the entire connection process. The OAuth flow handles authentication without requiring you to generate or paste an API key anywhere.
Step 2: Set GPT-5.3 Codex as Your Default
Once authentication is complete, set GPT-5.3 Codex as your primary model:
openclaw models set openai-codex/gpt-5.3-codexThis tells OpenClaw to route all requests through your ChatGPT subscription via the Codex provider. The model reference format follows OpenClaw's standard provider/model pattern, which you will see referenced throughout the documentation.
Step 3: Verify It Is Working
Run the status check to confirm the model is active:
openclaw models status --plainYou should see openai-codex/gpt-5.3-codex listed as your current primary model. If it shows up there, your ChatGPT subscription is now powering OpenClaw. No API key, no per-token billing, just your flat monthly rate.
If something looks off, go back to Step 1 and rerun the onboarding wizard. The wizard is safe to run multiple times and will not overwrite a working config.
The Self-Surgery Rule: Why You Should Never Configure OpenClaw From Inside OpenClaw
Here is a rule we follow without exception: always configure OpenClaw from Terminal or VS Code. Never ask OpenClaw to configure itself from within.
The reason is straightforward. If OpenClaw is changing its own model settings, authentication, or gateway config while it is running, you create a circular dependency. The agent is modifying the system it is currently running on. If something goes wrong mid-change, you can end up with a broken config and no clean way to recover through the same interface.
Terminal keeps you outside the system. VS Code, if you prefer a GUI editor, works the same way. You make the change, save it, and OpenClaw picks it up cleanly on the next run.
This applies to the model setup commands above, any gateway config edits, and any authentication updates. Always run those from Terminal.
ChatGPT Plus vs Pro: Which Plan Is Right for OpenClaw?
Most users will do well on ChatGPT Plus at $20 per month. If you are running OpenClaw as a daily AI assistant for personal or small business use, Plus gives you access to GPT-5.3 Codex and the standard Codex usage included in the subscription.
ChatGPT Pro at $200 per month makes sense if you are running OpenClaw in a higher-volume environment: multiple automations running throughout the day, complex multi-step tasks, or if you are using OpenClaw as part of an operational system with heavy throughput. Pro subscribers typically get higher rate limits and extended Codex access.
One practical note: OpenAI has confirmed that Codex usage is included in ChatGPT subscriptions. If you hit a usage ceiling on Plus during a heavy session, you will know it is time to look at Pro. But for most users starting out, Plus is the right entry point.
“Start with Plus. Move to Pro if volume demands it. Either way, you are off per-token billing.”
FAQ
Can I use my ChatGPT subscription with OpenClaw?
Yes. OpenClaw officially supports ChatGPT subscription access through OpenAI Codex OAuth. You connect it using the onboarding wizard with the --auth-choice openai-codex flag, and your subscription covers the usage instead of per-token API billing.
Does OpenAI officially allow this?
Yes. OpenAI has officially confirmed that ChatGPT subscriptions can be used with OpenClaw. Sam Altman has confirmed it publicly, and OpenClaw founder Peter Steinberger announced support on Twitter. The OpenClaw documentation also explicitly confirms Codex OAuth support.
What happened with the Anthropic Claude subscription?
Anthropic confirmed that using a Claude subscription to power OpenClaw falls outside their terms of service. That means Claude subscription users are not officially permitted to use it this way and risk losing access. Claude API keys (pay-per-token) are still a valid option, but a Claude subscription is not the same as an API key.
What is OpenAI Codex and why does OpenClaw use it?
OpenAI Codex is OpenAI's agentic coding and task model. GPT-5.3 Codex is the current version, described by OpenAI as their most capable agentic coding model, combining frontier coding performance with reasoning capabilities. OpenClaw uses it because it is built for the kind of multi-step, tool-using agent tasks that OpenClaw handles, not just simple chat responses.
ChatGPT Plus vs Pro for OpenClaw: which should I get?
Start with Plus ($20/month) if you are using OpenClaw for personal or small-business automation. Upgrade to Pro ($200/month) if you need higher Codex rate limits due to heavy daily usage across multiple automations or workflows.
Do I lose any OpenClaw features by switching from Claude to OpenAI?
No. OpenClaw is model-agnostic. The core features, channels, skills, and gateway all work the same regardless of which AI provider powers the model. You are just changing what is under the hood. If you want to switch back or run a different provider as a fallback, you can do that too.
Why should I use Terminal or VS Code instead of OpenClaw for config changes?
Because asking OpenClaw to modify its own configuration while running creates a self-referential problem. If the model changes go wrong mid-process, you can break the system you are using to fix it. Terminal keeps you outside the loop. You make the change cleanly, and OpenClaw loads it fresh on the next start.
Can I use OpenAI as a fallback alongside Claude?
Yes. If you have Claude set up via API key, you can add OpenAI Codex as an additional provider and configure it as a fallback. OpenClaw supports multiple model providers, and you can set priority order in your config. That said, given Anthropic's terms of service position on Claude subscriptions, the cleanest setup for most users is to make OpenAI Codex the primary.
