My friend just open-sourced Persome, a local-first macOS runtime that turns daily activity into structured context for AI agents via MCP.

Before AI, human leverage was 1×1. Agents made it 1×n. Now, we’re entering the n×n era: where one person becomes infinitely many selves, each thinking, creating, and acting in parallel.

Today we’re open-sourcing Personal Model: a local-first Personal Model for macOS, built from daily work on your computer, for AI agents over MCP.

Necessary difficulty is underrated.

Not all friction should be removed. In learning, some friction is the mechanism.

Taste requires eating. Learning requires chewing.

The trap with always choosing the easiest medium is that you may remove the exact friction that makes the idea become yours.

READ THE CODE

[Mitchell Hashimoto @mitchellh]

@poojabnf I read the code

[Alex Chen @ipruning]

Huge congrats!

I backed RepoPrompt from the first version with a lifetime license, and the o1 Pro + XML editing workflow left a real impression on me at the time.

Everything that came after, from rp-cli to the surrounding tooling, had such consistently good taste. I learned a lot from watching how you built.

Excited to see you bring that taste to OpenAI DX / Codex. Best possible collaboration.

Yesterday was my first day at @OpenAI working under the amazing @romainhuet.

I've spent the better part of two years pushing the frontier of having models write code for you, shipping updates week after week for @RepoPrompt.

Transitioning from being a founder is never easy, especially when you have a community of amazing developers who invested so much in your tool.

Thankfully Romain worked hard to ensure that all those users would be taken care in the process, and if you're one such user, you should have an email waiting in your inbox with the details!

I'm very excited to be joining this talented team and work alongside everyone at OpenAI contributing to codex.

We've reached an agreement to acquire Astral.

After we close, OpenAI plans for @astral_sh to join our Codex team, with a continued focus on building great tools and advancing the shared mission of making developers more productive.

This is an incredibly concise summary. In the age of coding agents: Make the change legible + testable, not easy.

[Kent Beck 🌻 @KentBeck]

for each desired change, make the change easy (warning: this may be hard), then make the easy change

[Alex Chen @ipruning]

@SonglinYang4 @MITEECS @thinkymachines Congrats!!!

[Alex Chen @ipruning]

Let's goooooooooooo

[Karl Clement @karlclement]

$ pip install amp-sdk

The Amp Python SDK is now available.

Given that half the planet seems to write Python, this felt overdue.

Enjoy building agents in the comfort of your own stack.

Anthropic CEO 3 months ago:
"Claude will replace developers."

Anthropic CEO today:
*spends big bucks to acquire a software engineering company*

AI: I will take your job.
Capital: You will take this stack trace.

All this time?
