Number 1. Logan Kilpatrick @OfficialLoganK Hot: seen more than 10K times on X
Google released Gemini 4 Carbon two weeks after Argon. It says Carbon is state of the art on cyber and long horizon tasks, ranks #1 on Artificial Analysis V5, and is better at coding.
What it means for your workIf you use Gemini for coding or long multi step jobs, rerun your hardest tasks on Carbon and compare before switching your default model.
Introducing Gemini 4 Carbon, it's a big jump over Argon which we released just 2 weeks ago. Gemini 4 Carbon is SOTA on cyber, long horizon tasks, ranks #1 on Artificial Analysis V5, significantly improves on usability in domains like coding, and is more aligned. https://t.co/Ikk9YedjCQ

Number 3. Claude @claudeai Hot: seen more than 10K times on X
Claude for Legal added a gallery of ready made artifacts for contract review, regulatory horizon scans, cite checks and more, which you can extend with your own documents and connectors and share.
What it means for your workSmall teams can start contract review or compliance scans from a template instead of a blank prompt. Still have a lawyer check anything that matters.
New in Claude for Legal: a gallery of ready-made artifacts for contract review, regulatory horizon scans, cite checks, and more. Start from the built-in example, add your own documents and connectors, and share it with anyone across the business. https://t.co/Wn2VK2HeMU

Number 4. unusual_whales @unusual_whales Hot: seen more than 10K times on X
House Democrats introduced a resolution saying Congress should not bail out AI firms in a financial crisis and that they should go through ordinary bankruptcy.
What it means for your workA resolution is not a law, so nothing changes yet. If you depend on one AI vendor, it is a reminder to keep a backup tool ready.
BREAKING: House Democrats have introduced a resolution that Congress should not bail out AI firms in the event of a financial crisis and should be subjected to the ordinary bankruptcy process.

Number 5. Liquid AI @liquidai Hot: seen more than 10K times on X
Liquid AI introduced LFM3, six small models across text, audio, vision and omni, including a 1.7B text model with 256k context, built to run on GPUs, CPUs and NPUs and fine tune on 1 GPU.
What it means for your workSmall models you can fine tune on one GPU and run on device are a cheaper, more private option for narrow jobs like tagging, voice or document triage.
Introducing 𝙻𝙵𝙼𝟹: our new generation of Liquid Foundation Models. With a new tri-hybrid architecture and new multimodal encoders, the LFM3 family is the ideal model suite for specialized intelligence. > 6 model instances, across text, audio, vision, and omni modalities, generative and decision models. > 𝙻𝙵𝙼𝟹-𝟷.𝟽𝙱: text, 256k context window. > 𝙻𝙵𝙼𝟹-𝚅𝙻-𝟸𝙱: vision-language model with video-input support for spatial understanding > 𝙻𝙵𝙼𝟹-𝙰𝚞𝚍𝚒𝚘-𝟸𝙱: tool calls, voice chat, reasoning in 18 languages. > 𝙻𝙵𝙼𝟹-𝙾𝚖𝚗𝚒-𝟸𝙱: an omni model combines vision, audio, and…

Number 6. Felix Rieseberg @felixrieseberg Hot: seen more than 10K times on X
An Anthropic manager says the coding interview no longer gives signal and removed it from his team's hiring loops this month, and argues this opens a door for junior engineers.
What it means for your workIf you hire developers, rethink take home and whiteboard tests and look at how candidates work with AI tools on real problems.
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: https://t.co/PVvpQCbQtK

Number 7. Artificial Analysis @ArtificialAnlys Hot: seen more than 10K times on X
Artificial Analysis launched Intelligence Index v5. 60% of it now uses private test sets or held out answers, and it adds FrontierCode 2.0 and Terminal-Bench-Science plus a new Progress Index.
What it means for your workPrivate test sets are harder to game, so v5 rankings are a more useful shortlist when you pick a model. Still test on your own tasks.
Announcing Artificial Analysis Intelligence Index v5, featuring 2 new benchmarks and 3 upgrades. For the first time, the majority of the Index is built on private datasets The Artificial Analysis Intelligence Index is our composite measure of model capabilities across tasks reflecting real-world usage today. v5 is our biggest upgrade since v4 launched in January. With v5, 60% of the Index is now based on evaluations with private test sets or held-out answers. Alongside Intelligence Index v5, we’re launching the Artificial Analysis Progress Index v1, which tracks model capability over time…

Number 8. Google DeepMind @GoogleDeepMind Hot: seen more than 10K times on X
Google DeepMind showed Genie 4, its most realistic interactive world model so far. You explore environments in real time, and scenes, sound and people respond, move and speak.
What it means for your workMostly a demo for now. Worth watching if you make training, product or marketing visuals, since interactive scenes could replace some video shoots.
This is Genie 4, our most realistic and interactive world model yet. 🌐 Explore dynamic environments in real time to see how the scene responds, sounds, and how the people in it move, react, and speak.

Number 9. Axiom @axiommathai Hot: seen more than 10K times on X
Axiom says it fully auto formalized the Classification of Finite Simple Groups in Lean, about 15,000 pages built by over 100 mathematicians, so the proof is now computer verified.
What it means for your workNothing to act on directly, but it shows AI can check very long, detailed work, which points toward verified reviews of contracts, code and specs.
The largest math proof in human history is now computer-verified. Today, Axiom announces a complete Lean auto-formalization of the Classification of Finite Simple Groups, the "periodic table of symmetry." About 15,000 pages, built by over 100 mathematicians across generations. https://t.co/Y1P26abyPQ

Number 10. Anthropic @AnthropicAI Hot: seen more than 10K times on X
Anthropic says its scientists have partnered with six organizations developing new medicines and started drug discovery work of its own, and shared early results on how Claude helps across drug development.
What it means for your workIf you work in life sciences, the blog post shows where Claude helped in real research. For most others there is nothing to act on.
Over the past few months, Anthropic scientists have engaged in deep research partnerships with six organizations developing new medicines. We've also begun drug discovery efforts of our own. In doing so, we’ve learned much more about how Claude can support the many stages of drug development. In this blog post, we share some early results from these efforts, and describe how this work fits in with our wider ambitions in the life sciences. https://t.co/EVbxkdDTgJ
