CODEX: future of knowledge work, Codex & ChatGPT merge, role-specific plug-ins

Huge week from OpenAI. They held a big event in New York and dropped a wave of Codex announcements — and it's now clear Codex is becoming the future platform for knowledge work, not just coding. We break down everything, plus test ChatGPT's new tool-calling live (with some very telling bugs). -------------- 📌 Build an MCP App with Fractal - Lovable for MCP Apps: https://usefractal.dev/ 📌 Get your Claude Connector & ChatGPT App organically discovered: https://www.agentdiscoverability.com 📌 MCP Registry Tracker: https://www.agentdiscoverability.com/... 📌 Join the #1 MCP & MCP App Community:   / discord   -------------- If you want to build your own ChatGPT App WITHOUT CODE, check out Fractal (https://usefractal.dev/) - it's Lovable for ChatGPT Apps - You can use code FRAC20 for 20% off. -------------- Here's what we cover: → Codex Is Merging Into ChatGPT: OpenAI is finally moving into super-app territory. What it means now that Codex becomes the harness powering ChatGPT. → Codex Sites: Build and deploy internal sites with a private shareable link — no deployment knowledge needed. Why this competes directly with v0, Lovable, and Replit. → Role-Specific Plugins: Bundles of MCP apps + skills for data analytics, sales, creative production and more. Why being the chosen tool inside a role is massive distribution. → The Open Ecosystem: Anyone will be able to build plugins, and plugins are coming to ChatGPT — not just Codex. → Codex Growth: ~5M users and roughly 400% growth this year. Why OpenAI now has "kingmaker" ability over tools. → MCP App Ecosystem Update: ChatGPT apps surge past 1,400 (+143 in a week) while Claude stays steady. New names: Strava, Iberia, Turkish Airlines, Disney Careers, Brex, Trainline. → ChatGPT's Improved Tool Calling: You no longer need to tag apps. We test it live and watch it auto-discover the right tool. → Why App Quality Is Everything: Expedia errors out and loses the query to Booking. Edge-case handling is now the difference between getting used and getting skipped. → Multi-Tool Chaining (First Time Seeing It): ChatGPT bundles flight + hotel across multiple apps in a single prompt. A big shift for discovery and surface area. → The Bigger Picture: Why MCP and MCP apps are becoming the core infrastructure for knowledge work — and the opportunity for builders in niche categories. Codex integrating into ChatGPT should land in the next couple of weeks. If you're building connectors, this is the moment to pay attention. 📌 Ghost Team: https://www.ghostteam.ai 📫 Newsletter: https://elliotgarreffa.beehiiv.com/ Follow for More AI Content: 🟦 LinkedIn:   / elliotgarreffa   🟦 X: https://x.com/elliot_garreffa 🟦 TikTok: /elliotagarreffa 🟦 Instagram: /elliotagarreffa Timestamps 00:00 – Intro: a huge week of OpenAI Codex announcements 02:09 – MCP app ecosystem: ChatGPT apps surge, Claude steady 04:05 – New apps landing: Strava, airlines, Disney Careers, Brex 06:33 – ChatGPT's improved tool calling (no more tagging apps) 09:55 – Why app quality is everything (Expedia errors out) 19:18 – Multi-tool chaining: flight + hotel in one prompt 22:09 – The OpenAI NY event: Codex announcements headline 23:36 – Codex comes to ChatGPT + the growth numbers 24:05 – Codex Sites: build and deploy internal sites instantly 29:36 – Role-specific plugins (data, sales, creative, legal) 35:31 – Open ecosystem: plugins coming to ChatGPT 38:34 – Wrap up + what's next
