Introducing the Printing Press, a CLI-factory and a CLI-library. Built with @trevin. 🏭🖨📚
Most APIs suck for agents. Most MCPs suck for agents. Most official CLIs suck for agents. They waste tokens and time. @steipete started making his own because of this.
📚 A Library of agent-native CLIs you install today (Linear, ESPN, Flight GOAT (Google Flights + Kayak nonstop), Contact Goat (LinkedIn + Happenstance + Deepline more) +30+ more)
🏭 A factory that prints new ones for any service - just type /printing-press
CLIs are fast, local, SQLite-backed. Work in Claude Code, Codex, OpenClaw, Hermes.

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.

@alex_frantic really did an incredible job with github.com/openai/symphony

People who join OpenAI are always surprised to learn that we basically ship stuff as soon as it’s ready

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

@tszzl @kimmonismus Can you just skip to 5.4 so I can get some sleep.

Seriously, I dont get it.
- Today, GPT-5.3 instant is being released .
- The blog post states at the very bottom that 5.3 Thinking and Pro will also be released very soon.
- An hour later, the official OpenAI X account tweeted that GPT-5.4 will be released very soon.
???
So in a few days we get: GPT-5.3 thinking + Pro + GPT-5.4 (???) instant/thinking/pro?
