🤖 ChatGPT adds a junior dev Codex, AI Employees are 🔥, 🐥 Ask the AI to rubber duck before diving in

🤖 ChatGPT adds a junior dev Codex
As the Windsurf acquisition is still in talks, ChatGPT is on a quest to eliminate junior devs. Codex pulls in your Github, cranks out features, fixes its own bugs, and writes unit tests. Codex is sandboxed so it can’t surf the Internet. That’ll eliminate some bad actors, but might be a little less useful.
Also it’s not supposed to be able to write code for “malicious intent” which I’m sure many will see as a challenge.
Fun Fact: OpenAI is rapidly expanding their product offerings: Sora (AI video gen), Deep Research, and Operator (web browsing agent).

🤖 AI Employees are 🔥
Suna, an open-source “generalist AI agent” from Italy-based Kortix, bills itself as a full-stack digital employee.
Agents are 🔥:
Manus AI also released a “think-and-do” chatbot.
Nimanode unveiled a no-code builder that spins up on-chain AI agents over the XRP Ledger.
Devin – “AI software engineer” that plans, codes, tests and ships features end-to-end for dev teams.
MultiOn – web-action agent layer that lets natural-language commands autonomously browse, click and automate online tasks
Adept ACT-1 – transformer-based agents trained to operate browsers and enterprise software tools
Fun Fact: Manus AI, a Chinese startup, got 2 million people on the waitlist in just 7 days.

Best from the community
While AI can work with “Build me X” it might be a little more effective to make it rubber duck itself a bit. Some architecture and tasks. Set some guardrails.
I promise you you’re vibe coding wrong
as someone who has built multiple production-ready applications, with thousands of users, from just Cursor with minimum intervention.
But first here's you (probably):
You open Cursor. Type “build me X.”
It spirals. Nothing works. You— vas (@vasumanmoza)
