Okay, quick correction on the EV Trip, I had the wrong date yesterday. I’m blaming full-on mommy brain 🤦‍♀️ I’ve fixed it, and yes, this trip actually starts one day earlier, on Saturday. COME TO THE BEIJING AUTO SHOW 2026 with @TechBuzzChina! You know we’ve been planning an EV trip for late April. We had some early sign-ups, but after getting thoughtful feedback from interested folks and past participants, we decided to redesign the whole thing. It’s now centered around the 2026 Beijing Auto Show, the biggest auto show in China. It’s held every two years and spans roughly 380,000 square meters of exhibition space -- think 50+ football fields worth of show floor. The show runs April 24–May 3 and brings together thousands of exhibitors and industry players across new energy vehicles, smart tech, software, robotics, and more. We’re pairing that scale with intentional curation: VIP access, private meetings, off-site experiences, and real expert networking. The goal is to make it feel focused, not chaotic, so you actually come away with context, not just impressions, about where EV and mobility are headed. It’s going to be packed, fast-moving, and genuinely fun. And you’ll be with @leixing77, who’s been deep in China’s mobility ecosystem for years and has led all of our past EV trips. If you’re attending the New Energy & Robotics trip the week before, you’ll get a discount if you sign up for both. Application link is in the comments.

I get better results from the Zhipu z.ai free agent than the Kimi Allegretto ($40/mo) paid agent who keeps on telling me it can't fulfill my request. I'm literally just running some research tasks. So weird. Just downgraded my subscription. Have also run into context window issues too. Am I missing something?!

The “genius girl” who previously worked at DeepSeek and was recruited by Lei Jun for Xiaomi AI is now on Twitter as well. It feels like more Chinese AI talent is realizing they can come here, speak for themselves, and build influence directly. I’m all for the added interaction and transparency.

MiMo-V2-Pro & Omni & TTS is out. Our first full-stack model family built truly for the Agent era. I call this a quiet ambush — not because we planned it, but because the shift from Chat to Agent paradigm happened so fast, even we barely believed it. Somewhere in between was a process that was thrilling, painful, and fascinating all at once. The 1T base model started training months ago. The original goal was long-context reasoning efficiency. Hybrid Attention carries real innovation, without overreaching — and it turns out to be exactly the right foundation for the Agent era. 1M context window. MTP inference for ultra-low latency and cost. These architectural decisions weren't trendy. They were a structural advantage we built before we needed it. What changed everything was experiencing a complex agentic scaffold — what I'd call orchestrated Context — for the first time. I was shocked on day one. I tried to convince the team to use it. That didn't work. So I gave a hard mandate: anyone on MiMo Team with fewer than 100 conversations tomorrow can quit. It worked. Once the team's imagination was ignited by what agentic systems could do, that imagination converted directly into research velocity. People ask why we move so fast. I saw it firsthand building DeepSeek R1. My honest summary: — Backbone and Infra research has long cycles. You need strategic conviction a year before it pays off. — Posttrain agility is a different muscle: product intuition driving evaluation, iteration cycles compressed, paradigm shifts caught early. — And the constant: curiosity, sharp technical instinct, decisive execution, full commitment — and something that's easy to underestimate: a genuine love for the world you're building for. We will open-source — when the models are stable enough to deserve it. From Beijing, very late, not quite awake.

In China, there is a joke going around right now that, 2026 is apparently the Year One 元年 of literally everything: 1/ autonomous driving 2/ liquid cooling 3/ domestic HBM 4/ on-device AI 5/ solid-state batteries 6/ AI applications 7/ quantum computing 8/ compute-memory integrated chips 9/ brain-inspired computing 10/ the low-altitude economy 11/ commercial space 12/ humanoid robots 13/ silicon photonics 14/ controllable nuclear fusion Is there a frontier technology that ISN'T going to hockey stick / cambrian explode this year???

Great video of a "tradesperson" who built software that exactly solves his own problems with Claude Code. I can't overstate how exciting this is I have also built a highly customized tool to manage our @TechBuzzChina trips, and my colleague joked that if the trips ever become unviable, I can always pivot into selling software for trip operators lol. Not quite the same economic value unfortunately
Todd Saunders@toddsaunders

I know Silicon Valley startups don't want to hear this..... But the combination of someone in the trades with deep domain expertise and Claude Code will run circles around your generic software. I talked to Cory LaChance this morning, a mechanical engineer in industrial piping construction in Houston. He normally works with chemical plants and refineries, but now he also works with the terminal He reached out in a DM a few days ago and I was so fired up by his story, I asked him if we could record the conversation and share it. He built a full application that industrial contractors are using every day. It reads piping isometric drawings and automatically extracts every weld count, every material spec, every commodity code. Work that took 10 minutes per drawing now takes 60 seconds. It can do 100 drawings in five minutes, saving days of time. His co-workers are all mind blown, and when he talks to them, it's like they are speaking different languages. His fabrication shop uses it daily, and he built the entire thing in 8 weeks. During those 8 weeks he also had to learn everything about Claude Code, the terminal, VS Code, everything. My favorite quote from him was when he said, "I literally did this with zero outside help other than the AI. My favorite tools are screenshots, step by step instructions and asking Claude to explain things like I'm five." Every trades worker with deep expertise and a willingness to sit down with Claude Code for a few weekends is now a potential software founder. I can't wait to meet more people like Cory.

Some incredible numbers being thrown around in this post re: Chinese humanoids, 80K units this year projected, almost triple 2025 volume, and the kicker: "the piece estimates each humanoid could replace 1.5-2 assembly-line jobs"
Tech Buzz China@TechBuzzChina

GGII, a Chinese robotics research firm, just put out a notably optimistic, data-heavy take on how quickly humanoids are moving toward commercialization. Here are some of its key claims: GGII says average unit cost fell to 100,000 yuan (~$14,300) in Q1 2026, down from 150,000 yuan (~$21,400) in 2025, while the average payback period shortened to 12 months, versus 18 months in 2025 and 48 months in 2023. There is also a price war. In March, UBTech reportedly cut its industrial humanoid to 128,000 yuan (~$18,300), Fourier launched the GR-3 at 115,000 yuan (~$16,400), and Unitree priced the G1 at 99,000 yuan (~$14,100), making it the first major model to break below 100,000 yuan (~$14,300). GGII frames 12 months as an important threshold. They quote a manufacturing CFO saying traditional automation usually pays back in 18-24 months, so if humanoids can reliably stay under 12 months, they become much easier to justify as capex. GGII projects 80,000 units shipped in 2026, up 185% from 28,000 in 2025. The piece also says Q2 2026 shipments alone could exceed 25,000, and that full-year shipments could be revised up to 100,000 if prices keep falling. Factory deployments are the main driver of that demand. GGII says factory use cases will account for 72% of 2026 demand, up from 65% in 2025, with the remaining 28% coming from logistics, security, and commercial services. One of the most concrete anecdotes is a factory case study. A Chinese auto-parts company reportedly bought 50 humanoid robots in 2025 for welding and assembly, invested 7.5 million yuan (~$1.07 million), then after 12 months had saved 6.8 million yuan (~$971,000) in labor costs, improved yield by 3.2 percentage points, and reached a combined payback period of 11.5 months. The market is already looking fairly concentrated. UBTech, Fourier, and Unitree together hold 70% share, with UBTech at 30% and 8,500 units, Fourier at 22% and 6,200 units, and Unitree at 18% and 5,100 units. Geographically, the Yangtze River Delta and Pearl River Delta still dominate, accounting for 68% of the market. But the piece says Sichuan, Hubei, and Anhui each saw more than 200% year-on-year growth, driven by auto and electronics clusters. The report is bullish, but it does acknowledge meaningful technical limits. Fault rates in unstructured environments are still 8-12%, versus 2-3% for conventional industrial robots. It also suggests current prices are not yet low enough for true mass adoption. According to the GGII survey cited, 65% of surveyed companies see 50,000-80,000 yuan (~$7,100-$11,400) as the real psychological price band for large-scale adoption. The labor implications are large if these shipment numbers prove right. The piece estimates each humanoid could replace 1.5-2 assembly-line jobs, implying that 80,000 shipments could theoretically affect 120,000-160,000 jobs. On competition, GGII notes that Tesla, Xiaomi, and Huawei are all looming in the background. The piece says Tesla Optimus is expected to begin small-batch deliveries in H2 2026, while Xiaomi and Huawei have announced humanoid strategies but remain pre-deployment.

How the metacognition / framework teaching with the 3.5 year old is going: Me: So, what is knowledge? And what is wisdom? Toddler: Knowledge is what I learn in my study apps! (the mini games we've built together) Me: What about wisdom? Toddler: Wisdom is mommy! Me: Do you know why I'm laughing? Toddler: Because I'm so right! Me: I mean, wisdom = mommy is not a bad mental shortcut loooool

This wouldn’t surprise me. On my WeChat Moments (~6K people), the only people talking about OpenClaw were the usual suspects. Nobody unexpected, like random aunties or grandmas, entered the conversation. And most of what I saw were just meetups. I didn’t see any first degree connections share stories about them making (any kind of) money from it.

@mrltinvesting Claude Code like everyone else :) I tell it to only use methods proven by learning science and minimize stimulation and most gamification on purpose as well.

I don’t think most parents realize it’s now faster to vibe-code a little learning app for your kid than to research and download one. Not kidding. I made this in about five minutes because my toddler wanted to learn some Korean to show off to their BFF. I wanted them to improve their Chinese so it's Chinese-to-Korean.

Wow, we technically only have one spot left for the pilot cohort of the Youth Tech China Trek!! And thanks in part to friends like @GlennLuk helping spread the word, we’ve ended up with a strong group of American kids too (it's seriously difficult to get Americans to join the investor trips, you've heard me rant about this before). Anyway, I expect we’ll open additional weeks soon. Also, one thing we will do very actively (that we should probably promote more as part of this program) is connect participants with Chinese middle and high school students and parents, STEM undergrads, PhDs, and early-career people in China. I’m intensely curious myself: what are the kids actually in the trenches studying, what are they spending their time on, what is the market rewarding, and how is everyone responding to / feeling about the shifting ground beneath all of our feet?!
Rui Ma@ruima

I mentioned this to the WSJ last year, but ... youth edition of our China Tech investor trips is here! (The idea actually came from those who came with us on the investor trips, a bunch of them said they wanted their kids to see it too) The pilot trip is going to be July 12-19, 2026 in Beijing for kids ages 12–17. If there's enough demand, we will open up more slots, just fill out the interest form! (And yup, we’ll launch a college-age version soon too!) If you have a teen who’d be into this, here it is 👇 Link and full information below

@ryan_nguyen200 Actually coding uses fewer tokens than research lol. For things like this for sure you’d be able to do it on the $20 plan
