It presents ChatGPT Web, including the Pro tier, as a native model inside OpenAI's Codex app by serving a local Responses API backed by an embedded-browser ChatGPT Temporary Chat. It is about thirty-two thousand lines of TypeScript with more than forty test files.\n\n**Sessions.** Task-bound. Sequential messages reuse one Temporary Chat under a conversation key with a per-turn lease. At the context boundary a retained agent writes a checkpoint before a clean chat starts, with tests for rolling checkpoints and compaction.\n\n**Completion.** A DOM observer keyed on ChatGPT's revision attributes, reporting whether the copy-turn action is visible and the stop button gone. All selectors live in one file, the cleanest selector layering found.\n\n**Tools.** Not prompt-and-scrape. It runs a real MCP server and registers it as a ChatGPT connector over an OpenAI tunnel, so ChatGPT's own server-side agent loop calls the tools natively, scoped by a per-turn capability token retired at settlement.\n\n**Its pitch.** The README badge reads \"Free AI with no API fees\" and the title promises use \"beyond Codex usage limits\". It is also candid that Temporary Chat \"is a ChatGPT privacy mode, not anonymity or local-only inference\" and that the project is unofficial.\n\n**Why it matters here.** It shows what robust looks like for one host and one provider: real conversation continuity, a structured completion signal, and the vendor's native tool protocol. The miscsubjects gateway trades that depth for breadth, five vendors behind one contract, and for participation in a capability graph rather than one editor.","register":"reference","hero":null,"hero_brief":"","editorial_review":null,"tags":["reference","browser-models","mcp"],"category":"reference","style":{},"claims":[{"id":"c1","text":"codex-chatgpt-web by miuuyy (5,023 stars on 2026-09-06, created July 2026) is the one project in the browser-model space with real adoption.
