Mark Zuckerberg's post on X, curated on eChai

Founder Notes

Curated from X →

Mark Zuckerberg co-founded Facebook, now Meta, and is its chief executive. Muse Code is Meta's coding agent, worked from the terminal and built on Muse Spark 1.2, a coding model trained alongside the agent rather than wrapped around a general one. It keeps a repository of thousands of files in a 1M-token context window, splits a large job across sub-agents that each work in their own git worktree so parallel edits do not collide, and prints every sub-agent, tool call, steer and cancel to an event log. Muse Code is not new today: it opened in early beta on 5 August 2026, priced from $5 a month with $15 and $50 tiers above it, and a cheaper contributor tier in some countries in return for Meta training on your prompts and completions. What this post adds is that the beta is over.

Muse Code is out of beta and now built to handle bigger, more complex engineering tasks. Developers can get started with one command today:

curl -fsSL https://dev.meta.ai/install.sh | bash

yesterday's eChai Ventures Mumbai Startup Meet - September Edition turned into a crazy conversation with Zaiba Sarang, Uday Wagh and Shreyaan Daga.

Zaiba, co-founder of iThink Logistics that helps eCommerce brands ship their products smoothly and efficiently. Her story of being born into a lower middle class family and turning her life around while studying hard through scholarships, becoming a top ranking student and now running a company with 4 other co-founders that is on the way to do 150 crore ARR truly touched my heart.

Uday, founder of TwinSim AI that helps startup founders test markets before they enter the real one. He shared his story of building 3 UPI apps back when it was just the beginning. He shared how he paved his way through raising funds from outside of India and offering vendors as small as chat wala's a free sev puri to their customers if they downloaded their app. IKR! 🤷♂️ He got an exit and got back to building TwinSim AI.

Shreyaan, founder of oll.co who proudly dropped out and now teaching students robotics, ai, coding, entrepreneurship, financial literacy etc. the skills needed for a brighter future. He right away entered the B2B market and directly started tapping into schools. No B2C. No Meta Ads. Nothing! He's teaching about 50,000 students a day and his goal is to get to 1 billion students a day.

of course, there's always Q&A, I mean that's important right?!

this time we spent more time in the Q&A as it was a houseful. a lot of founders asked a lot of thoughtful questions and got real value from these veteran founders.

overall, it was a Saturday well spent.

always thankful to Jatin Chaudhary co-founder of eChai Ventures for consistently organising such meet-ups in Mumbai and such other cities across globe.

☕ An evening at AI Café by eChai Ventures x House of Starts!

It was a great space to connect with founders, students and people from diverse backgrounds who are interested in AI and building something with it. The conversations, exchange of ideas and the demo & pitch session made it a really interesting experience, especially seeing how people are exploring AI in their work and products.

Definitely a Friday well spent! ✨

Ok, jev is really cool. So many great use cases where a fast and accurate yes/no gate can deliver meaningful performance gains.
