dsh-chatgpt-web turns your local browser session of ChatGPT into a seamless, $0.00 API-free conversational model provider directly inside DeepSeek Harness (DSH).

It connects via headless or visible Chrome/Chromium browser automation to chatgpt.com, streaming real-time Markdown responses, code solutions, explanations, and reasoning back to your DSH chats without consuming API credits. Why Pure Chat?

Small conversational web models (like GPT-6 Luna) excel at explanations, dialogue, Q&A, brainstorming, code snippet generation, and side-assistant tasks. By running in Pure Chat Mode, the bridge eliminates prompt overhead, tool hallucinations, and syntax errors of autonomous multi-tool execution loops, providing a fast, rock-solid, zero-cost LLM provider. Key Features 100% Free ($0.00 Cost): Uses your existing free ChatGPT Web session. No OpenAI API keys or credit cards needed. Cordis Plugin-First Lifecycle: Managed by DSH via ctx.effect. DeepSeek Harness starts the background sidecar automatically on launch and shuts it down on exit. Dynamic Model Auto-Detection: Automatically detects your ChatGPT tier: Free Accounts: Defaults to chatgpt-web/luna (gpt-5-6-luna) and chatgpt-web/think. Plus / Team Accounts: Automatically detects and exposes GPT-6 (chatgpt-web/gpt-6-light, medium, high) and GPT-5.6 Sol (chatgpt-web/light, medium, high), plus Pro tiers when available. Full Streaming Markdown & Code Blocks: Delivers tokens in real time directly to the DSH Web UI or CLI. Portable, Validated Artifacts: The published tarball is validated by CI (clean install, runtime smoke test, d

Install the plugin directly from this GitHub repository:

This registers the plugin in the profile's package.json bundles, so its Cordis entries are composed automatically — no manual insert is needed. 2. One-Time Browser Sign-In

Authenticate your ChatGPT account once. The plugin binary lives in the profile's node_modules/.bin:

A dedicated Chrome/Chromium window will open. Log into your OpenAI / ChatGPT account. Once the composer is visible and the ChatGPT session is authenticated, setup captures the session and writes the config and browser state to the plugin's storage directory (default ~/.dsh/storages/chatgpt-web/). A guest composer alone is not treated as a successful login.

--dsh leaves Codex configuration and OS services untouched; DSH owns the sidecar lifecycle. Existing Codex or DEV storage cannot be repurposed by this command: use a separate DSH_CHATGPT_WEB_HOME if needed. Before rerunning setup, stop or disable the sidecar so its port is free. Without --dsh, the legacy Codex setup path remains unchanged.

If your browser is not at the default path, pass it explicitly:
