Access GPT-5.4 via Codex subscription in OpenClaw
How to configure OpenClaw for GPT-5.4
A user on r/openclaw has shared a method for accessing the GPT-5.4 model via an OpenAI Codex subscription within the OpenClaw framework. The process involves patching the configuration as the model is not currently listed in the standard catalog.
The core instruction is to direct your primary AI coding agent to execute the task using a specific prompt: Research on how to patch openclaw with the new openai GPT 5.4 model.
Configuration Steps
The key change is made within the openclaw.json configuration file. The required modifications are hosted in a GitHub Gist: https://gist.github.com/Jacksunwei/3886b95ceacb3ba6af985350a3bdb6ec.
After applying the JSON patch, you must restart the OpenClaw gateway with the command: openclaw gateway restart.
Testing the Setup
To verify the configuration is working, initiate a chat with your agent using the model identifier: /model openai-codex/gpt-5.4. Follow this with a simple message like "Hi" and check the system logs to confirm GPT-5.4 is being utilized.
The post is framed as an interim option, mentioning that update "2026.3.7 just dropped" and suggesting this method "while we're waiting for next release."
