Have you ever thought to yourself: I really don't want to make this PowerPoint.
Good news: ChatGPT can now create and edit presentations directly in PowerPoint.
Build, update, understand, and polish presentations directly in PowerPoint while keeping slides editable.
Now in beta, we’d love your feedback 👀

Learning how to use coding agents effectively is the most interesting engineering problem in the world right now.
The solution @alex_frantic came up with for our team is Symphony.
I think Symphony has a few really interesting ideas embedded in it:
1. The approach itself. Giving coding agents access to task tracking and changing their goal to "convince a human to merge this code" is the clear next phase of software engineering.
2. Software as a spec. Instead of code, Symphony is first a spec.md that you can materialize into any programming language you want by passing it to your coding agent of choice. This is an early demonstration of a new way I expect open-source software to be developed and shared in the future.
3. Lowering the cost of code. When reliably kicking off a feature or bug fix is something you can do from your phone in a few seconds, it radically changes your relationship with product prioritization and exploration.
Read the whole blog post below and let me know what you think.

📣 What if every open issue had a Codex agent?
That’s the idea behind Symphony, an open-source agent orchestrator for Codex that turns task trackers into always-on systems for agentic work, letting humans focus on review and direction.

Incredibly impressed with the care and craft the team put into this product. It's been a lot of fun to chat with all the (mostly useful) bots people have built internally
Introducing workspace agents in ChatGPT—shared agents that can handle complex tasks and long-running workflows across tools and teams.

Totally normal timeline we live in to have buckled my laptop into the backseat of my SUV so it can be tethered and let 4 tmux sessions of GPT-5.2 Pro cook #Codex

📣 Shipping software with Codex without touching code.
Here’s how a small team steering Codex opened and merged 1,500 pull requests to deliver a product used by hundreds of internal users with zero manual coding.

I’m very excited that we’re finally publishing a deep dive into how my team has been working for the last 6 months.
@_lopopolo is a real visionary and it’s been a blast working with him.

Not writing code by hand has been a big shift for sure. Unexpectedly, it’s also been really fun. As @_lopopolo likes to say “we just do the fun parts of engineering on this team”
