通过在授权持有者的 Chrome 页面和干净的 API 之间转换，实现对 Node 对 ChatGPT（包括 Pro）** 的程序访问。

就像罗塞塔石碑一样：一边是专业网页协议，一边是普通的Node API。

它的作用

• Pro 支持：runConversation({ model: "gpt-6-pro", ... }) 在 stream_handoff 事件之后，打开 WebSocket 第二条腿，并聚合实时的 CoT，直到 message_stream_complete ——与 chatgpt.com UI 相同，但可从 Node 返回。
• 即时模型也一样：非Pro的slugs（gpt-5-6默认;gpt-5-5是网页界面的极速通道）通过同一路径在几秒内返回。
• 多回合：传递conversationId + parentMessageId（或使用recall: "thread"进行持久化）。
• 并发：每个调用生成自己的标签页;许多调用可以并行流。
• 实时令牌deltas：可选的onChunk(delta)回调在CoT到达时进行流式传输。
• 闲置超时看门狗：长时间思考（15分钟+），只要守望者发送心跳，就继续;只有真正的静默才能终止呼叫。

安装

需要节点≥22。

设置：启动Chrome

你需要一台打开--remote-debugging-port并且登录一次 chatgpt.com的Chrome。

rosetta

Programmatic access to ChatGPT (incl. Pro) from Node, by translating between an auth-holder Chrome page and a clean API.

Like the Rosetta Stone: the Pro web protocol on one side, a regular Node API on the other.

What it does

• Pro support: runConversation({ model: "gpt-6-pro", ... }) follows the stream_handoff event, opens the WebSocket second leg, and aggregates the live CoT until message_stream_complete — same UX as the chatgpt.com UI but returnable from Node.
• Instant models too: non-Pro slugs (gpt-5-6 default; gpt-5-5 is the web UI’s 极速 lane) return in seconds via the same path.
• Multi-turn: pass conversationId + parentMessageId (or use recall: "thread" for persistence).
• Concurrency: each call spawns its own tab; many calls can stream in parallel.
• Live token deltas: optional onChunk(delta) callback streams the CoT as it arrives.
• Idle-timeout watchdog: long thinks (15 min+) keep going as long as the WS sends heartbeats; only true silence kills the call.

Install

pnpm add @syntaxsmith/rosetta
# or
npm i @syntaxsmith/rosetta

Requires Node ≥ 22.

Setup: launch Chrome

You need a Chrome with --remote-debugging-port open and logged in to chatgpt.com once. Profile is reused across runs.

Linux

chromium \
  --remote-debugging-port=9222 \
  --user-data-dir=$HOME/.rosetta/profile \
  --no-first-run --no-default-browser-check \
  https://chatgpt.com/

macOS

"/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" \
  --remote-debugging-port=9222 \
  --user-data-dir=$HOME/.rosetta/profile \
  --no-first-run --no-default-browser-check \
  https://chatgpt.com/

Windows (PowerShell)

& "C:\Program Files\Google\Chrome\Application\chrome.exe" `
  --remote-debugging-port=9222 `
  --user-data-dir=$env:USERPROFILE\.rosetta\profile `
  --no-first-run --no-default-browser-check `
  https://chatgpt.com/

Sign in once; the profile persists. Subsequent runs reuse the cookies.

CLI

# default = Pro (gpt-6-pro, GPT-6)
rosetta run "Explain idempotent matrices in three sentences."

# cheaper tier via explicit slug
rosetta run -m gpt-5-6 "Reply with the single word: pong"

# stream live tokens
rosetta run --stream "Sketch a 3-paragraph plan for X"

# threaded recall — successive calls build on the same conversation
rosetta run --recall research "what's the prior on Y?"
rosetta run --recall research "given that, what would change?"

# inspect / clear persisted threads
rosetta threads
rosetta forget research

# list models the account exposes
rosetta probe

# attach a local file (repeatable) — image, PDF, CSV, code, ...
rosetta run --attach photo.png "What's in this image?"
rosetta run --attach report.pdf "Quote the third paragraph verbatim."
