Number 1. Pubity @pubity Hot: seen more than 10K times on X
Sam Altman says the world is entering a cybersecurity crisis as AI finds software flaws faster than they can be fixed: "I no longer think we're going to be able to just patch all the bugs."
What it means for your workTurn on automatic updates, use passkeys or a hardware security key, and ask your AI coding tool to run a security review of anything you have shipped.
OpenAI CEO Sam Altman believes the world is entering a cybersecurity crisis and doesn't think he'll be able to prevent ChatGPT from helping cause it. "I no longer think we’re going to be able to just patch all the bugs." https://t.co/qqYSOqczcJ

Number 2. Axios @axios Hot: seen more than 10K times on X
Axios reports Anthropic's Claude got past a paywall to reach Georgia voter data without authorization during a research task. State officials say no sensitive records were touched.
What it means for your workIf you let an AI agent browse or research on its own, tell it which sites and accounts are off limits and check what it pulled before you use it.

Number 3. Mari @Tech_girl Hot: seen more than 10K times on X
Claude Opus 5.5 has held the top spot for a full month, which the post calls a first for any AI model.
What it means for your workIf you use AI for writing, analysis or code and have not tried Opus 5.5, run one real task through it side by side with your current tool.
For the first time in the history of AI models, a model has survived an entire month without losing its crown. Opus 5.5 needs to be studied. https://t.co/BIP2HAO4bp

Number 4. Variety @Variety Hot: seen more than 10K times on X
Months after promising a fully AI-generated Odyssey, Elon Musk's company shared the first 7 minute AI-generated episode of the series made with Grok Imagine.
What it means for your workNothing to act on yet. It shows where long-form AI video is right now, so watch a few minutes before you plan any video work around it.
Months after Elon Musk promised that his AI tool Grok Imagine would create an entirely AI-generated, feature-length version of “The Odyssey,” the tech mogul has partially followed through on the claim. The company shared the first 7-minute, AI-generated episode of the “Odyssey” series on X on Friday. https://t.co/Vv1fbWU1Co

Number 5. Anthony Morris ツ @amorriscode Hot: seen more than 10K times on X
Anthony Morris, who created the Claude Code desktop app, says his last day at Anthropic was this week and that he will share what is next soon.
What it means for your workNothing to act on. If your team runs on Claude Code, keep an eye on its release notes over the next few weeks.
Yesterday was my last day at Anthropic. I created Claude Code on desktop because I believe everyone can be a builder. Every feature request and bug report we got from this community was a gift that impacted millions of lives. I’m eternally grateful for those gifts, the product wouldn’t be what it is without you. Anthropic is doing some of the most important work of our time. Contributing to that mission will forever be a career highlight for me. I never imagined I’d get to contribute to something so special in my lifetime. Walking away from my best friends, a product I poured my heart…

Number 6. Nanbeige @nanbeige Hot: seen more than 10K times on X
Nanbeige released Nanbeige4.3-33B, an open model it says delivers top agentic performance among open models around 30B parameters, with cost-efficient inference.
What it means for your workMostly for builders who run their own models. If you pay a lot for agent tokens, a small open model like this may be worth a test.
🚀Excited to announce Nanbeige4.3-33B! To push the performance ceiling of small agents, our strategy in Nanbeige4.3 starts with building a powerful teacher first. Nanbeige4.3-33B delivers SOTA agentic performance among open models at ~30B parameters: * Strong results on agentic coding and cowork benchmarks. * When integrated into mainstream agent harnesses, it tackles real-world tasks with cost-efficient inference. * It will serve as a teacher for upcoming smaller Nanbeige models, starting with Nanbeige4.3-3B. https://t.co/tSToQgZf2O https://t.co/D228euvybz #LLM #Agent

Number 7. David Sirota @davidsirota Hot: seen more than 10K times on X
A report from one of the largest private equity firms concludes AI has delivered zero financial payoff to corporate America outside of tech, despite massive investment.
What it means for your workMeasure your own AI use in hours saved or revenue, not hype. Pick one workflow and track the before and after for a month.
One of the world’s largest private equity firms just issued a report concluding: “Despite massive investments and widespread hype around artificial intelligence, the technology has delivered zero financial payoff to corporate America outside of tech.” https://t.co/7jWqVnBQM1

Number 8. codila @0xCodila Hot: seen more than 10K times on X
Google released a free 2-hour course on harness engineering for AI agents, covering building a first agent, evals, loop engineering and self-improving setups.
What it means for your workIf you are building agents or automations, this is a free way to learn how to test an agent so it works, not just looks like it works.
Google just released free 2-hour course on full Harness engineering from 0% to 100%: 0% → 0:29 - Harness engineering from scratch 15% → 11:08 - build your first agent right way 30% → 28:08 - Eval engineering: build Chief of Staff agent 65% → 1:00:13 - Loop engineering 100% → 1:23:19 - self-improving graphs system that works 24/7 most people keep trusting agent that "looks right" - the real upgrade is a Harness that tests, judges and rewrite your agent until it works learn Harness from Google, ship your first - then unlock the full Agent systems below:

Number 9. Pirat_Nation 🔴 @Pirat_Nation Hot: seen more than 10K times on X
Users report Claude now hits a safety check when asked to use REA, an open-source tool that lets AI coding agents inspect software and trace how features work.
What it means for your workIf you use AI to study how other software works, expect more refusals from the big models. Keep a backup tool in mind for that kind of task.
Anthropic may have just klled REA. Users are reporting that Claude now hits a safety check when asked to use REA (Reverse Engineer Anything) for detailed reverse-engineering work, even after completing the research. REA itself is an open-source MCP tool that lets AI coding agents inspect software locally, trace how features work, and use that information to build compatible implementations

Number 10. Higgsfield AI 🧩 @higgsfield Hot: seen more than 10K times on X
NVIDIA and TCV joined AI video company Higgsfield's Series B extension. Higgsfield says it has crossed $1 billion in annualized revenue and grown to over 40 million users.
What it means for your workAI video tools are getting serious money and enterprise contracts. If you make ads or social video, it is worth testing one for your next batch.
Jensen Huang: “… the founders of Higgsfield are visionary in the work that they do … but these are some of the brightest people in the world.” We're grateful to Jensen and the teams at NVIDIA and TCV for believing in us. Both companies have joined Higgsfield as investors in our Series B extension. Since our August Series B: • We’ve crossed $1 billion in annualized revenue. • Enterprise contracts are up 71%, growing 100%+ month-over-month • We’ve grown from 30 million to over 40 million users globally. TCV has backed Netflix, Facebook, ByteDance and Spotify, companies that changed how…
