OpenAI's general-purpose AI assistant for drafting, analysis and research, with file uploads, deep research and image creation. Paid plans add Projects, scheduled tasks, custom GPTs and more Codex usage; MCP tools connect through plugins.
OpenAI lists Free ($0), Go ($8/month, may include ads), Plus ($20/month) and Pro (from $100/month, three usage tiers), plus Business and Enterprise priced per user. Checked 2026-10-17. source ↗
ChatGPT on the web uses remote MCP tools through plugins; the ChatGPT desktop app, Codex CLI and IDE extension can connect directly to MCP servers and share one configuration. source ↗
How ChatGPT connects to each AI platform: native connector or MCP, API through code the agent writes, browser control, or file upload.
| Platform | MCP / connector | API (agent-written code) | Browser | Upload / export |
|---|---|---|---|---|
| Claude (incl. Claude Code) | No documented route | Confirmed Claude (incl. Claude Code) can run code; ChatGPT publishes an API. Claude (incl. Claude Code) docs ↗ | Confirmed Claude Code with the Claude in Chrome extension (Chrome, Edge and other Chromium browsers) Claude (incl. Claude Code) browser docs ↗ | Confirmed Export from ChatGPT, then works on the files in your project; chat accepts attachments Claude (incl. Claude Code) docs ↗ |
| OpenAI Codex | No documented route | Confirmed OpenAI Codex can run code; ChatGPT publishes an API. OpenAI Codex docs ↗ | Confirmed Only in the ChatGPT desktop app; not in the Codex CLI or IDE extension OpenAI Codex browser docs ↗ | Confirmed Export from ChatGPT, then works on local repositories OpenAI Codex docs ↗ |
| Google Antigravity | No documented route | Confirmed Google Antigravity can run code; ChatGPT publishes an API. Google Antigravity docs ↗ | Confirmed Browser subagent via /browser, documented as an Antigravity App feature; the IDE has separate browser docs Google Antigravity browser docs ↗ | Confirmed Export from ChatGPT, then works on local projects and worktrees Google Antigravity docs ↗ |
Confirmed means both the tool's and the platform's official docs describe that route (links in the cell); IonBin has not tested every pairing. Not documented means it may work, but no official docs describe that route end to end. Checked Oct 17, 2026.
