Starship V3 first flight in about 4 weeks

Today we’re introducing Meta AI Voice Conversations powered by Muse Spark that let you talk naturally to Meta AI (interrupt, switch topics, or swap languages), and as you talk, Meta AI can generate images and pull up recommendations from Reels, maps, and more. We’re also bringing live AI to the app, so you can point your camera at the world and ask about what you’re seeing in real time. about.fb.com/news/2026/04/in…

Gemini 3.5 Flash is on the Pareto frontier of cost per intelligence on Vending Bench (a measure of a models ability to run a simulated store)!

BREAKING: The U.S. Government has officially announced that @Tesla and LG ​Energy have signed an agreement to ‌build a $4.3 billion lithium iron phosphate (LFP) prismatic battery cell manufacturing factory in Lansing, Michigan, with a 2027 start of production. "American-made cells will power Tesla's Megapack 3 energy storage systems produced in Houston, creating a robust domestic battery supply chain," the U.S. Department of the Interior said in a statement. Here's everything you need to know about Tesla's new Megablock, the latest in the company's industrial storage product lineup, which includes the new Megapack version 3: Megablock: • 23% faster to install with up to 40% lower construction costs • Plug and play platform (hardware, software and services) delivered as one all from Tesla. It's a pre-engineered medium-voltage block that integrates next-gen Megapack 3 • Eliminated above ground cabling between the transformer and the megapacks using new flexible busbar assembly • 91% MV round trip efficiency • 20 MWh of usable AC energy • Operates in temps of -40°C (-40°F) to 60°C (140°F) • 248 MWh per acre • 25-year life & >10,000 cycles • With Megablock, Tesla is targeting to commission 1GWh in 20 business days, equivalent to bringing power to 400,000 homes in less than month Megapack 3: • Will be manufactured in Tesla's upcoming Houston Megafactory starting in late 2026. 50 GWh annual manufacturing capacity when fully ramped. • 5 MWh of usable AC energy • Weight: 86,000 lbs • 28 foot long enclosure that can be shipped globally • Optimized for up to 8-hour applications • New drastically simplified thermal bay. Uses Model Y heat pump, but on steroids. 78% fewer connections, which minimizes failure points • Larger battery module and larger battery cell • 2.8 liter battery cell, co-engineered with Tesla's cell team • LFP battery • Operates in -40°C to 60° • Went from 24 cable connections in Megapack version 2XL, down to 3 simple busbar connections • 75% of the mass of Megapack 3 is battery cells. • A single module in it weighs as much as a Cybertruck • Tesla has enabled easier front access service, so there are no roof penetrations • Drastically simplified bussing system

By this weekend, xAI will have three Grok Build models in training simultaneously

"I wake. I charge. I clean. I drive." The Cybercab doesn't just move you - it takes care of itself Robotic arm cleans the interior between rides No driver. No janitor. No manual plug-in The future is not just autonomous driving It's an autonomous existence

Andrej Karpathy just dropped a project scoring every job in America on how likely an AI will replace it from 0-10 > Scraped all 342 occupations from the Bureau of Labor > Fed each one to an LLM with a detailed scoring rubric > Built an interactive treemap where rectangle size = number of jobs and color = how exposed that job is to AI The key signal in his scoring: if the work product is fundamentally digital and the job can be done entirely from a home office, exposure is inherently high. The scale: 0-1: Roofers, janitors 4-5: Nurses, retail, physicians 8-9: Software devs, paralegals, data analysts 10: Medical transcriptionists Average across all 342 occupations: 5.3/10. The entire pipeline is open source. BLS scraping, LLM scoring, the visualization. All of it. Much respect for the sensei this is scary and awesome

🚨 BREAKING: Someone just open-sourced software that sees you through walls using only WIFI signals. it’s called WiFi-DensePose. It maps your exact body pose in real-time. no cameras. no sensors. just your living room router. 100% Open Source.

The next step for autoresearch is that it has to be asynchronously massively collaborative for agents (think: SETI@home style). The goal is not to emulate a single PhD student, it's to emulate a research community of them. Current code synchronously grows a single thread of commits in a particular research direction. But the original repo is more of a seed, from which could sprout commits contributed by agents on all kinds of different research directions or for different compute platforms. Git(Hub) is *almost* but not really suited for this. It has a softly built in assumption of one "master" branch, which temporarily forks off into PRs just to merge back a bit later. I tried to prototype something super lightweight that could have a flavor of this, e.g. just a Discussion, written by my agent as a summary of its overnight run: github.com/karpathy/autorese… Alternatively, a PR has the benefit of exact commits: github.com/karpathy/autorese… but you'd never want to actually merge it... You'd just want to "adopt" and accumulate branches of commits. But even in this lightweight way, you could ask your agent to first read the Discussions/PRs using GitHub CLI for inspiration, and after its research is done, contribute a little "paper" of findings back. I'm not actually exactly sure what this should look like, but it's a big idea that is more general than just the autoresearch repo specifically. Agents can in principle easily juggle and collaborate on thousands of commits across arbitrary branch structures. Existing abstractions will accumulate stress as intelligence, attention and tenacity cease to be bottlenecks.
