This is Pele, my new rendering library for diagrams and charts, compatible with the latest Mermaid syntax.
- 100-500× faster than mermaid.js
- 6× smaller bundle
- No dependencies
- Easy to theme
- Responsive to device width
In pursuit of making Obsidian insanely fast and cohesively designed, I always found the Mermaid library to be too big, too slow, and too hard to theme. Pele will be the new renderer in the next version of Obsidian, but you can start using it now.
Pele [ˈpɛlɛ] is named after the goddess of volcanoes and fire. It's open source under the MIT license. Try the playground!

We keep improving performance across Claude, and you may have noticed it starts responding sooner!
Claude Code now gzips the conversation it sends on every turn, so it reaches the model faster. Cloud sessions also start up as soon as you start typing.

We've been working hard on making the Claude Code desktop app great for running lots of sessions side by side.
It's now much quicker to start sessions, easier to split work across a few, and you can always see what each of them is doing. Here’s what's new:

Apple never built this, so someone hacked it with $7.
esp32-iphone-agent lets an AI model use a real iPhone through a tiny ESP32 board plugged into the charging port. No jailbreak, no Xcode, no developer account.
how it works:
• eyes → the iPhone screen mirrors over AirPlay to your computer
• hands → the ESP32 acts as a USB mouse and keyboard
• brain → any OpenAI-compatible vision model plans and taps
• limits → it can't see passcode or Apple Pay screens, by iOS design
why it matters:
→ AI agents on real phones, not emulators
→ about $7 of hardware
→ open source, MIT license
Your iPhone just got an AI driver, and Apple wasn't involved.

An example of the /state-machine skill in practice.
Made a couple of improvements so it scales better when working with a lot of different states.
I added a new /state-machine skill to the collection.
It renders any component you want in all of its states on a throwaway page with mock data.
I enjoy working like this a lot. It makes it very easy to work on more complex components.

Closed source is dead.
REA lets Claude Code or Codex take apart any app, all the way down to the binary, and explain exactly how a feature works.
- Native apps, Electron apps, websites, APKs, firmware, even smart contract bytecode
- Shows the evidence for every claim
- Then builds its own version of the feature
25,000+ GitHub stars in a single day. 100% open-source.

Day 2.1/
We have made Auto-review free for all users signed in through a ChatGPT account. You can enable it in settings > permissions > auto-review. Auto-review improves upon the default sandbox setting that requires you to approve everything, which is prone to decision fatigue unless you spend a lot of time configuring specific rules.
It allows you to run long tasks while having a second agent review all actions taken by the primary agent. Its only goal is to prevent high-risk actions from being taken and to protect against unwanted actions that are not aligned with the original user intent. This Auto-review feature is now free and does not draw usage from your plan.
Day 1/
We have optimized the default speed to be ~50% faster across GPT-6 Astra and GPT-6.1 Sol through the subscription across all our products and partners using Sign in With ChatGPT (including OpenCode, Pi, Amp, Devin, ...).
No changes needed on your end and this should be felt within the next two hours.
