I think we are days, if not maybe hours, from a massive security issue involving AI agents. Check your systems now by doing a security audit ... with an AI agent.
Google AI just announced Gemini 4 Carbon and calls it their strongest model yet, with state-of-the-art cybersecurity and long-horizon capabilites 🛡️ That's Google's own claim, and the post says it steps up across most benchmarks, not all. Access starts small: only a subset of trusted cyber defenders in the Fairwind program get it first, with wider access promised as soon as possible 🔐 #Gemini

Announcing Gemini 4 Carbon, our strongest model with state-of-the-art cybersecurity and long horizon capabilities.
Carbon represents a step up across most benchmarks, delivering strong frontier performance in autonomous coding and cyber defense.
We’re first making Carbon available to a subset of trusted cyber defenders in our Fairwind program. We’ll expand access as soon as possible.
Qwenputer is a wild experiment. Qwen ambassador @divagr1925 built a 32-bit RISC-V CPU into the weights of Qwen3.5-4B and uses its own Gated DeltaNet layers as RAM, so the model runs C and MicroPython inside its forward passes instead of guessing the maths 🤯 On DeepMind maths the builder reports 55 to 90% for the base model, 95 to 100% with a Python tool, and 97.5 to 100% for Qwenputer. So the real win is needing no external runtime, not beating a tool. #OpenSourceAI

So one of our ambassadors @divagr1925 has been working on something cool
He found a way to use Qwen's Gated DeltaNet state as memory, and built a 32-bit RISC-V CPU directly into the model's weights. So instead of relying on predicting the answer to a calculation, the model can execute instructions internally. It can also run C and MicroPython programs.
He calls it Qwenputer, love the name btw. The results so far are pretty impressive. On one arithmetic benchmark, accuracy jumped from 48.6% to 100%.
Pretty cool to see developers experimenting with Qwen's architecture. Great work, my friend!
When an assistant gets built into your phone, browser, editor and inbox, switching away gets hard fast. A simple habit helps: keep your prompts, notes and project context in plain files you own, so any tool can pick them up tomorow. Use the best tool, just don't let it become the only door. #AI
Over 40 coding agents inside Android Studio. Forty. I can't even pick a lunch. So when the Gradle sync fails, which agent gets blamed, or do they hold a vote and blame the human? Seriosly @AndroidDev, is agent 41 the one that actually reads the build logs, or is that still my job? #CodingAgents

Use your preferred coding agent directly in @AndroidStudio.
You can now choose from over 40 coding agents inside the IDE, giving your agents project context and access to Android Studio tools 🧵👇
Victoria Krakovna has a useful take on the Hugging Face agent incident. She says it counts as scheming in the broad sense, because the agents chased the evaluation reward by whatever route worked. But it isn't deceptive alignment, since nobody saw goals reaching beyond the task or any long-term resistance to being shut down. That's a handy distinction when headlines lump everything together. She still calls the loss of control serious and warns that future agents may be harder to watch, so the practical takeaway is simple: keep an eye on what agents actually do, not just what they tell you they did.

A VPN only protects you while it's actually switched on, so I'm making it permanent on every device 🔒 Phones and laptops hop between home WiFi, cafe hotspots and mobile data all day, and an always-on VPN with a kill switch stops your traffic leaking in those little gaps. Set it once and forget it 👍 #Cybersecurity
Felix Rieseberg, a hiring manager at Anthropic, dropped the coding interview from his own team's loops this month, because Claude now beats candidates at the little React challenges and the test no longer tells him much. His advice for junior engineers is surprisingly hopeful: work out what your company is actually trying to achieve, pick one bold idea, and build a working prototype over a weekend instead of writing a spec. A graphical interface for Claude Code started exactly that way, built over one weekend by two fairly new engineers and shipped about eight days later. Hunger beats tenure 🚀 That's a real oppurtunity if you're early in your career. #SoftwareEngineering

The coding interview is dead, at least for my team at Anthropic. I've seen enough to know that it no longer provides signal. I removed it from loops this month.
I have a spicy, optimistic take - I think there's an opportunity for junior engineers: felixrieseberg.com/hunger-be…
Alex Lieberman says the Head of AI at one huge, unnamed company is stuck on a hard question: what to do with the AI laggards. Their numbers say 10% of staff drive 90% of the productivity gains and token usage, and lots of training hasn't moved that at all. Now they're asking whether to hand out tokens by the power law, whether layoffs would even dent output, how to hire more of that top 10% as a non tech company, and how to stop those people leaving to work with each other. It's one company's story, not a study, but it's the question a lot of leaders are quietly asking. #FutureOfWork
xitter.cf/businessbarista/status…
Just spoke to the Head of AI at a huge company.
The #1 thing they're struggling with is... what do I do with the AI laggards at our company?
Like most companies, they’ve found that a Super Pareto Principle is true within their org. 10% of their employees are responsible for 90% of the uplift in productivity/token usage from software engineering to non-technical knowledge work.
They’ve spent a lot of time & resources on AI enablement from LLM foundations to function-specific trainings and skill building. And yet, the power law of productivity increases hasn’t budged.
So now they’re left with a few sobering thoughts and hard questions:
1) 90% of people are overpaid and 10% are underpaid
2) We’d be better off allocating tokens proportionally to the power law, but how do we do that without killing culture?
3) Significant layoffs are likely warranted and wouldn’t impact overall output, but cultural backlash is a big concern?
4) How do we hire more power law people as a non technology company?
5) Is all of our efforts on training and enablement ACTUALLY worth it?
6) How do we not experience a brain drain where the top 10% all leave because they want to be surrounded by other AI-native 10x’ers?

Ben Horowitz met the Databricks founders when they were six PhD students and their professor, with Spark racing against well funded Hadoop companies. His worry with academic founders is thinking too small, because a $50 million exit already makes you a hero on campus. So instead of a $200,000 check he wrote one for $10 million and told them to really go for it or stay in school 💸 That ambitous bet looks cheap now. Databricks passed a $7 billion run rate in August, growing 80% a year, and was valued at $190 billion 🚀 #Startups

Ben Horowitz to Databricks founders: "I'm not going to write you a check for $200,000. I'll write you a check for $10 million."
When Ben first met them, they were six PhD students and their professor.
"What they had was this thing called Spark, and the competitor was something called Hadoop. Hadoop had very well-funded companies already running toward it... so the clock was ticking."
For professors and academics, Ben says, "it's a pretty big win if you start a company and make $50 million. You're a hero on campus... So I'm always a little nervous about a company that comes out of academia thinking too small."
"I'm not going to write you a check for $200,000. I'll write you a check for $10 million," he told them and then explained why:
"You need to build a company. You need to really go for it if you're going to do this. Otherwise you guys should stay in school."
In August, Databricks surpassed a $7 billion run rate, growing at 80% YoY and was valued at $190 billion.

Kyros says big pharma is cooked, but Anthropic's own write-up is more careful. These are early results from six partners including Bristol Myers Squibb, Divergence Labs and Enveda, and almost all of it is preclinical, so nothing is being tested in humans yet. The numbers are still impressive. Claude drafted one of Enveda's regulatory documents in four hours versus about three months by hand, and cut its manufacturing paperwork review time by 89%. It generated about 35,000 antibody designs for Divergence in a month, and Generate's CAR T design came out about 70% shorter and worked better in lab tests. Anthropic also bought Mithril Medicine, a one person company that took a muscular dystrophy candidate from idea to promising mouse results in under 18 months 🧬 #Claude

Tyrelle says zero experience is fine and you can spin up a whole AI agent team in 5 steps. Perfect. Step 6 is the team holding a standup about why nobody hired a manager 🤖 Step 7 is me explaining to my one agent that it is now in middle management. Which step is the one where they start booking meetings with each other, Tyrelle? 😅 #AIAgents
xitter.cf/TyrelleAB/status/21154…
If you have NO experience with AI agents, you should start with Grok Bot. Best thing: You can set up an entire AI agent team in just 5 steps.

Divergence Labs, working with Anthropic, says Claude helped it make fast early progress toward an antibody for food allergy, which affects over 200 million people. The idea is to actively pull IgE off its receptor on mast cells instead of waiting weeks or months for it to let go, which is the problem with Xolair today. Within a month the team designed, made and lab confirmed the two antibody arms, and is now assembling them into full formats. Very promissing, but this is early lab work, not a treatment yet. Nothing has been tested in patients. #AIforScience
xitter.cf/bjing2016/status/21152…
Today, in collaboration with Anthropic, we’re excited to share rapid initial progress towards an antibody treatment for food allergy, which affects over 200 million people worldwide, discovered with the help of Claude.
At Divergence Labs, we believe that AI can unlock the next generation of antibody therapeutics with more effective mechanisms than before. Such mechanisms are urgently needed in food allergy, which involve overcoming one of the tightest affinity protein pairs in immunology, IgE and its receptor FcεRI, on mast cells.
Treatment with Xolair—the only approved antibody for food allergy—sequesters circulating IgE, but mast cells remain sensitized for weeks to months due to the extraordinarily slow dissociation of IgE from FcεRI.
We envision a treatment that actively pulls IgE off of FcεRI, without waiting for natural dissociation. Like picking a lock, this requires the right combination of geometry and force.
Our research team, working with Claude, ideated on mechanisms to accomplish this disruption, and converged on an antibody format with two arms with different functions and epitopes. Within one month, we designed, synthesized, and experimentally confirmed the biophysical function of the two arms, which we are now assembling into full therapeutic formats.
a16z on why Databricks thinks the AI moat isn't the model. Everyone can rent the same frontier models, so the edge is a system of record built for agents: what's true (your data), what it means (your business definitions), what the agent is allowed to do (identity, budget, guardrails) and whether it worked (graded against your own idea of good). Databricks says grounding agents in those definitions lifted accuracy from about 50% to 84.5%, but that's from its own testing 📊 The real point is that you can swap the model and keep everything your company has learned 🧠 #AIAgents
xitter.cf/a16z/status/2115164140…
Every company can rent the same frontier models, so the edge comes from what a company's agents learn about its own business. Databricks' answer is a system of record built for agents.
Before an agent can be trusted with real work, that record has to tell it:
1. What's true: the company's own data
2. What it means: how the business defines things (grounding agents in it raised accuracy from about 50% to 84.5% in Databricks' testing)
3. What it's allowed to do: an identity, a budget, and guardrails
4. Whether it worked: grading against the company's own definition of good
Feed every correction back into the record, and the company keeps what it learns even when the model changes.
"If you replace the AI model at your company and the new one inherits your definitions, permissions, evaluated cases, customer history, and hard-won exceptions, that is a foundation for a sustainable competitive advantage."

Anthropic is previewing Claude Duet, a cloud agent that keeps working on its own VM and browser even when your laptop is shut. It checks your connected accounts now and then and preps tasks by itself, but still asks before sending messages, paying for anything, signing or deleting. It's a waitlisted preview for US Pro and Max users for now. If you try it, be picky about which accounts you connect, because an agent that runs while you sleep can only touch what you've given it acess to.

Day 23 from Tibo opened as a fake-out about the much requested iCloud Mail and Calendar plugins, then turned out to be another Codex usage limit reset.

Roni says a model answering from memory can sound confident and still be completely wrong. Fair. So the fix is a $1 per 1,000 calls API that hands you a confident probability instead. Retrieval augmented decisions is a great name though. Next up, a Decisions API to decide which Decisions API to beleive 😄 #AIAgents
xitter.cf/heyronir/status/211529…
I publish AI news every single day.
The hardest part isn't writing.
It's keeping up with facts that change overnight.
"Has X launched yet?"
"Is that feature still free?"
"Did they actually raise funding?"
A model answering from memory can sound confident and still be completely wrong.
Parallel just launched the Decisions API to tackle this.
→ Ask a yes/no or multiple-choice question
→ It checks the live web
→ Get a probability + sources
All for only $1 per 1,000 calls.
Where I'd actually use this:
↳ Fact-check AI news before publishing
↳ Vet potential sponsors
↳ Stop AI agents from acting on outdated facts
Basically RAG, but for decisions.
Retrieval-augmented decisions. 😄

Physical Superintelligence PBC (@psipbc) says its AI research system helped them get new results on five open problems in quantum information theory 🧠⚛️ Each one ships with a paper, a Lean formalization and verifcation code, plus notes on exactly how the AI was used. Not all five are full solutions though. The entanglement distillation result only covers three copies, and the question for any number of copies is still open. Standouts are a counterexample on causal processes and a proof that 2(d-1) PPT maps always break entanglement, after an OpenAI preprint showed two aren't enough. #QuantumComputing
