Just landed at Bangalore airport. Bangalore is still 2 hours away. So let me tell you about what’s happening today. First edition of Agentic by @eigencloud at @localhosthq. Packed lineup. @aashatwt is demoing some crazy things she has built with vibe coding. Real builders showing what they’ve built on Eigen. Then a panel on what AI actually means for India and what to build. AI founders and builders all in one room. Brought to you with our partners @innercircle_so , @aiweekendsxyz , and @devfolio. See you at 5 PM.

@aakashgupta wait this is wild so they basically ran the perfect blind taste test and crushed every labeled model makes you wonder how many other "hardware" companies are quietly sitting on frontier AI teams

Aakash Gupta@aakashgupta·
The entire AI industry spent a week convinced DeepSeek had secretly launched V4. Reuters reported it. Developers debated it. OpenRouter usage charts broke. It was Xiaomi. A smartphone and electric vehicle company just shipped a 1-trillion-parameter model that topped the world's largest API aggregation platform, and nobody guessed the origin because the model was too good to be associated with a hardware company. The stealth launch as "Hunter Alpha" on March 11 was the most elegant product validation in recent AI history. No brand, no attribution, no expectations. Just raw performance. The model processed over 1 trillion tokens in 8 days. Developers organically chose it over every labeled frontier model on the platform. When Reuters tested the chatbot, it identified itself only as "a Chinese AI model primarily trained in Chinese" with a May 2025 knowledge cutoff, the exact same cutoff DeepSeek reports. The person behind this is Luo Fuli. Born in 1995. Eight papers at ACL as a graduate student at Peking University. Alibaba DAMO Academy. Then DeepSeek, where she co-developed V2 and contributed to R1. Lei Jun reportedly offered tens of millions of yuan to recruit her. She joined Xiaomi in November 2025. Four months later, she's shipping a model that benchmarks alongside Claude Sonnet 4.6 and GPT-5.2 at one-fifth the API cost. The detail that tells you everything about how this team operates: when Luo first experienced a complex agentic scaffold, she tried to convince the MiMo team to adopt it. They resisted. So she issued a mandate. Anyone on the team with fewer than 100 conversations with the system by tomorrow can quit. They all stayed. The imagination converted into research velocity. The architectural bets matter. Hybrid Attention for long-context efficiency. MTP inference for low latency. 1M context window. 42B activated parameters out of 1T total. These are infrastructure decisions optimized for agents that run autonomously for hours, not chatbots that answer one question at a time. Pricing: $1/$3 per million tokens up to 256K context. $2/$6 for 256K to 1M. Claude Sonnet 4.6 costs roughly 5x that. Xiaomi's shares rose 5.8% on the announcement. The real DeepSeek V4 still hasn't shipped. The model everyone mistook for it already has a trillion tokens of real-world usage data.

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.

OpenAI didn’t just acquire a startup. They acquired the muscle memory of 10 million Python developers. Astral, the team behind uv, Ruff, and ty is now inside Codex. The default toolchain of Python developers. Let that sink in. This isn’t another “AI writes code” update. This is AI owning the entire development loop. → Plan the change → Spin up environments with uv → Type-check with ty → Lint with Ruff → Ship All… without breaking flow. And the smartest part? They’re keeping everything open-source

Vibe coding startups won’t like this. Lovable hit $400M ARR selling what google almost gave away for free. They just made production-grade full-stack development… free. Here’s what Google AI Studio just shipped 📷 → Build multiplayer apps with real backends from a single prompt → Installs missing libraries on its own,no prompts needed → Knows when your app needs a database and spins one up automatically → Keeps full memory of your project across sessions → Firebase Auth and Cloud Firestore, ready out of the box → Handles API keys for payments, maps, and databases seamlessly → One click → production deploy. Done. The only moats left? Distribution. Data. User trust. Not features.

Lately, Claude makes some shocking mistakes. ⟶ Implements overly complex code ⟶ Ignores the codebase's code style ⟶ Removes working code for no reason ⟶ Replaces code that's out of scope from the task at hand It feels like it needs 100% supervision. At this point, you're better off writing everything yourself.

the enterprise play makes sense but you're right about the consumer problem I think the unlock is when these tools become so good that a solo builder can actually ship and monetize fast enough to justify the sub. like if I could go idea to revenue in a week consistently, $20/mo is nothing but we're not there yet. still too much manual work after the vibe coding part

Vibe coding products are at an interesting predicament. If I buy a $20/mo subscription of v0, Replit, Lovable etc, either I am paying or my employer is paying for it. If I'm paying out of my pocket, I have to make money with it. Otherwise I'm canceling it the month after. Simple as that. No individual would make a ton of apps / landing pages every month to justify keeping this subscription on. That leaves the enterprises. There, I don't see there being 10s of winners either. Replit has sold to many large companies their vibe coding platform. Enterprise revenue is sticky and will be slow-churning. Every PM / Eng / Designer out there is building prototypes. Lots of hype. This will continue to do well. But if a vibe coding platform isn't selling to enterprises, selling to consumer won't work. So Lovable's move is not surprising but paints a grim picture – what other direction can these products expand to? Hosting? Backend + databases? Domains? More B2B use cases? And even if they do, can they win there given each of them are saturated spaces with their own winners at the moment.

@sniffshiba congrats on shipping! totally feel you on the exit logic being harder than entry. been there with my own trading experiments. curious what made you launch during a bear market vs waiting? feels counterintuitive but maybe that's the point

I’m thrilled to announce the beta version of my automated trading project, Sniffing Siri. 
Even without any professional coding knowledge, I managed to build a program that actually executes real trades using just vibe coding. I launched it right in the middle of bear market and have been experiencing some truly brutal stop-loss hits. 
I’m realizing more and more that the exit/sell logic is far more important than the entry/buy logic. I’ll keep running it for about a month, and if I start to feel a sense of stability, I’ll consider increasing the seed capital. Special thanks to 지표견 @danjang1205 who developed the indicators that made this possible, and also huge gratitude to @DeepDive_KR for the development help and providing the statistical data. I’ll continue upgrading it step by step and work on pushing the returns higher. Thank you all! 🚀

@ClementDelangue been thinking about this exact thing for People Loop the cost savings alone would be insane if you could route simple questions to smaller models and only hit the big ones for complex stuff are you seeing demand for this kind of routing at HF?

Someone should build a truly multi-model agent that switches between hundreds of different specialized models for different tasks (including even maybe local models ultimately?) Feels like it would increase speed, affordability & powerfulness by an order of magnitude for agents and doable with inference providers on Hugging Face and Hugging Face skills!

@irentdumpsters been there with bad accountants. they just file stuff and disappear when you need them curious what specific thing Brad did that actually made you money vs just saving it?

The reason why we started working with Brad it was because we got absolutely shelled by our last accountants. Signing up with Brad literally made us money, more than it saved us money...... It's important to have an accountant who's transparent and not trying to build a big firm
Brad Nelson | CPA & Fractional CFO@bradncpa

Some of the most profitable businesses can still overpay 6-figures in tax every year because nobody ran the W-2 math before December. Once a business crosses $200,000 in profit, the tax playbook changes and you need to have a different conversation. If your adjusted gross income (AGI) is below certain levels, you can get the qualified business income deduction even if you did not pay any W-2 wages. Above those thresholds, the deduction gets capped by W-2 wages actually on payroll. For single filers, that cutoff lands around $197,000 in AGI. For married filing jointly, it sits around $400,000. A company running entirely on 1099 contractors at that income level needs to see this coming before year-end. No W-2 wages above the threshold means no deduction. That gap can be tens of thousands of dollars every single year. One route you can take is transitioning some of the workforce to W-2 before December 31st. Another is finding ways to bring AGI below the limitation while there is still time. Both work when the conversation starts in October. One call in Q4 can change the outcome more than anything done after January 1st. If you found this helpful, follow @bradncpa for more breakdowns like this.

Its a day traders market today in #ES_F and all about 6623 support posted 8am. We've been testing/trapping all day, and just hit it again. No change: 6635 reclaims see (6642 - hit 2x), 6658-62. No rally today until that recovers Bears control fully under yesterday's 6716 support
Adam Mancini@AdamMancini4

First micro squeeze of the day in #ES_F but bears retain full control below 6716 and we can only sustain a rally today when 6658-62 recovers. After spending the morning trapping/testing 6623 support, I posted 6635 reclaims see 6642 (hit), 6658-62 above. Same supports downside
