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 👀

We’re expanding our partnership with @SpaceX, and will be scaling up on GB200 capacity in Colossus 2 throughout June.

Appreciate @elonmusk and the team helping us find good homes for the Claudes.

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.

@alex_frantic really did an incredible job with https://t.co/HyM4517hjS

One easy trick to connect 25 Codex agents to Linear and increase your PR throughput by 500% that THEY don't want you to know about

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

@3ameam Try the App instead of the cli, I’m a recent convert

Codex for (almost) everything.

It can now use apps on your Mac, connect to more of your tools, create images, learn from previous actions, remember how you like to work, and take on ongoing and repeatable tasks.
