Codex Connect Plus

English | 中文

Use your ChatGPT/Codex subscription inside DeepSeek Harness for Codex models and gpt-image-2 generation/editing—without an OpenAI Platform API key.

Sign in once with ChatGPT OAuth. Codex model requests use the signed-in account's subscription capacity; image generation/editing uses the same OAuth session and remains subject to account availability, region, limits, and upstream policy.

What you get

• Codex models in the normal DSH model picker — no separate CLI workflow.
• gpt-image-2 generation and editing — create images from prompts or edit 1–8 local references, with inline previews and local output files.
• No OpenAI Platform API key or pay-as-you-go API billing setup — authorization comes from your user-approved ChatGPT/Codex OAuth session.
• Quota-conscious defaults — automatic model retries default to 0, and image requests are never silently retried.

Features

• ChatGPT/Codex OAuth login and provider-native automatic refresh.
• OpenAI Codex model catalog through Harness's normal LLM service.
• Optional standalone Codex search provider.
• Optional view_image tool for vision-capable models.
• codex_image_generate for 1-4 gpt-image-2 outputs.
• codex_image_edit for 1-8 local PNG/JPEG/WebP references and an optional mask.
• Durable DSH attachments, session-authorized replay, inline preview, and local files under outputs/codex-image.
• Fixed upstream origins, no redirects, bounded inputs/responses, cancellation, timeout, strict image signatures, and redacted provider errors.

Requirements

• DeepSeek Harness 0.1.0-rc.7 or newer. This release is adapted to the rc.7 keyed-slot settings-card API. On older Harness versions the package still installs (the plugin system does not enforce peer ranges), but the Plugin configuration card may not render, so upgrade Harness first or stay on 0.1.0-beta.2 for 0.1.0-rc.5/rc.6-era Harness.
• Node.js ^22.19.0 || >=24.0.0.

Install

Install the public npm beta:

dsh plugin --profile web add dsh-codex-connect-plus@beta

Immutable GitHub fallback:

dsh plugin --profile web add 'github:stoneface10/dsh-codex-connect-plus#v0.1.0-beta.4'

A matching .tgz is also attached to the GitHub prerelease.

For local development:

dsh plugin --profile web add link:/absolute/path/to/dsh-codex-connect-plus

Do not install dsh-codex-connect, dsh-codex-image-connect, and this combined package in the same profile: they own the same provider and tool names.
