Dear Readers,
Sometimes you can feel it very clearly: progress does not come in small steps, but rolls over us like a wave. Today's edition captures precisely this moment – from the leap from codex models to real coding agents to robots that get right back up after being knocked down. It's about how machines are no longer just tools, but are beginning to participate as independent partners in our processes. The question is: Are we ready to accept this new division of roles?
The following lines are about Codex as the next big building block for developers, OpenAI's return to robotics with a clear commitment to the physical world, and RoboBallet, where robot arms interact like dancers in perfect choreography for the first time. There are also exciting insights into new business models, fresh research results, and unexpected everyday applications. Stay tuned—this mix of vision and practice is worth looking forward to.
In Today’s Issue:
🧑💻 OpenAI's Codex just got a huge upgrade
🐕 Unitree's robots are more stable than ever
🤖 OpenAI is diving back into robotics focusing on humanoid systems.
👯♀️ "RoboBallet" AI can now choreograph multiple robot arms
✨ And more AI goodness…
All the best,
ChatGPT's New Personalization Hub

GPT-5 Integrated into Xcode 26
OpenAI has announced that Xcode 26 is now available on the Mac App Store, allowing developers to sign in with their ChatGPT account and utilize GPT-5 directly within their coding environment.
No router this time for the 5 codex model.

After OpenAI's new GPT-5-codex model, it may not be long before Anthropic responds with Sonnet 4.5.
New ChatGPT Model: GPT-5 Codex
The Takeaway
👉 Codex is evolving from pure autocomplete to a true coding agent that takes on tasks independently.
👉 With a new CLI, IDE integration, and cloud environment, a consistent workflow is growing without tool hopping.
👉 Security mechanisms such as approval modes and sandbox usage make agentic coding more controllable.
👉 The integration of image inputs and pull request reviews opens up new possibilities for teamwork and code quality.
It feels like the moment when an intern is promoted to project manager: with GPT-5 Codex, Codex is focusing on “agent-based” coding and now works where you build anyway—terminal, IDE, web, GitHub, even mobile. In short: less prompt gymnastics, more real implementation.
What's it all about? OpenAI bundles Codex into a seamless experience: a revamped CLI (open-source), an IDE extension for VS Code/Cursor, and a cloud environment that takes on tasks—from feature builds and large refactors to integrated code review in pull requests. Added to this are security guardrails (approval modes, sandbox without standard network access) and practical extras such as image inputs for UI bugs or design specs.
Why is this exciting for the AI community? Because Codex doesn't just “help,” it takes over work: independently processing long tasks, checking PRs, maintaining context between local and cloud sessions. Teams get speed plus quality control—without tool hopping. The vision: a controllable agent that thinks, tests, and iterates like a reliable colleague.
Why it matters: Agentic coding workflows are moving from hype to everyday use. Those who integrate early ship faster, with less friction—and build a more robust delivery pipeline.

Unitree enhances stability
In this impressive video, we see how Unitree ensures that the stability of its robots is significantly improved. Despite being punched and kicked, the robot immediately gets back up.
OpenAI returns to robotics
OpenAI is stepping up its involvement in robotics and bringing new top researchers such as Chengshu Li on board. The focus is on combining simulation, teleoperation, and AI to develop humanoid systems with better perception and control. After years of restraint, OpenAI is showing that the physical world is once again taking center stage—a crucial step on the path to useful real-world AI agents.
RoboBallet: AI orchestrates robot arms
A team from UCL, DeepMind, and Intrinsic has unveiled “RoboBallet”—a system that coordinates multiple industrial robot arms simultaneously. Eight arms completed 40 tasks in seconds, a job that would previously have taken days. The approach: instead of programming rigid paths, the system learns general principles of collaboration. For factories and production, this could herald a new era of efficiency and flexibility.
