🎯 What it does: Sign in with a ChatGPT / Codex subscription to enjoy powerful GPT models, image generation, and web search in DeepSeek Harness, with subscription quota reporting included.
🧩 Compatibility: Verified on DSH0.1.0-rc.6; future releases will continue to be tested against the latest DSH version.
⚠️ Risk: This project is built on open-source software and relies on non-public ChatGPT Codex backend endpoints. OpenAI protocol changes may temporarily break features until the plugin is updated, and there may also be a low risk of account suspension.
✨ Plugin highlights
- 🚀 Direct subscription access — GPT models, image generation, and web search share your OpenAI subscription quota.
- 🧩 Controlled integration — the model picker, generated images, and web search integrate into DeepSeek Harness with dedicated controls.
- 🔐 Multiple sign-in methods — supports browser sign-in and headless device-code authorization.
- 🌗 UI adaptation — follows DSH's English/Chinese language and Light, Dark, or System theme.

⚙️ Detailed configuration
No configuration is normally required. Available options are:
| Option | Default | Description |
|---|---|---|
dshHome | DSH Home | Custom DSH home directory used to resolve default file paths. |
path | $DSH_HOME/codex-oauth.json | Host-side OAuth credential file. |
preferencesPath | $DSH_HOME/codex-oauth-preferences.json | Model visibility and feature switches; defaults beside path when it is overridden. |
issuer | https://auth.openai.com | OAuth issuer; override only for gateways or tests. |
usageUrl | https://chatgpt.com/backend-api/wham/usage | Subscription usage endpoint. |
controlPort | 1456 | Loopback login, status, and preference service. |
redirectPort | 1455 | Loopback browser OAuth callback. |
Search model | gpt-5.6-sol | Model used by hosted web search, aligned with the default Codex Power configuration. |
Example Cordis configuration:
- insert:
- id: dsh-codex-oauth
name: "@wnjxyk/dsh-codex-oauth"
config:
dshHome: /data/dsh
path: /secure/codex-oauth.json
preferencesPath: /secure/codex-oauth-preferences.json
issuer: https://auth.openai.com
usageUrl: https://chatgpt.com/backend-api/wham/usage
controlPort: 1456
redirectPort: 1455
- id: codex-web-search
name: "@wnjxyk/dsh-codex-oauth/web-search"
config:
model: gpt-5.6-sol
Web search and image-generation orchestration both default to the Codex Power model gpt-5.6-sol; images are rendered by the hosted GPT Image (image_generation) tool; chat models are discovered dynamically from the openai-codex model provider supplied by DSH's built-in llm-pi-ai plugin.
