@akkkkiira @ArgaLabs @jtaylor yes! everyone needs red teaming

Introducing @ArgaLabs' newest feature: red-team your agent, hosted on any software, autonomously. We built infrastructure that enables us to recreate a behavioural clone of any app, aka Digital Twin (inspired by @jtaylor), extremely fast. Here’s an example of Arga testing newly-added guardrails to a bot in our Discord digital twin. The clones have full official API/SDK support, are fully functional, and you can directly preview your changes on the Arga website. We also support red-teaming on your app — where we spawn a swarm of agents into your app, hosted in our remote sandboxes. Our agents understands your program by gathering external context (we support almost every mainstream platform out there) to generate user stories, and they click through like real users to uncover unexpected behaviour. Let our agents find bugs, because you were never meant to be QA for AI.

@JaiRelan @AlexaKayman @AJDungate Thanks Jai! 👋

@AlexaKayman Not sure if you’ve bumped into them but @AJDungate, @SepandD do a lot of cool work in the space!

Warning: Very long deep dive into the hull inspection industry. Optimal for learning about a new (or old), extremely valuable space.

Agreed. Part of OnDeck and my thesis is that: - systems will prevail in performance, - todays models are severely underutilized. And tomorrow’s too, leaving a gap. - multi-step reasoning can close the gap, and do so faster than base model improvements or tuning on every single domain will

@ycombinator @proliferateai Awesome stuff, congrats Pablo!

Local coding agents can't do end-to-end work at your company. @proliferateai is the open-source platform for company-specific agents that can. Provision secure access to your tools, set up automations, and let agents work in the background. Congrats on the launch, @thepablohansen! ycombinator.com/launches/PVw-p…

@paramendra Hey Paramendra, thanks for reaching out. This is not something we’re looking for at the moment. Keep building!

Hello @SepandD I am building an AI applied to Marketing tech startup and would greatly appreciate being able to do marketing for you as an outside consultant. AI + Marketing netizen.page/2026/01/ai-mar…

@arlanr 🚀 Some good gatherings last week!

we gathered the most cracked people from MIT and Harvard and threw an amazing event with friends from YC. thanks to everyone who came!

+1. Overlaps with our reasoning for building the applied research startup that is solving visual reasoning.

Personally very excited to discuss VLMs and long-context reasoning!

@gpusteve Congrats. A fast takeoff scenario!

for the first time in my twitter history im follower ratio positive. time to switch up on my day ones

✅ Thanks for listening! 🫶 Big shoutout to @AJDungate, very proud of you constructively standing up. YC, 🇨🇦 appreciates you a lot.

@RyanJunejo @ycombinator 👀 @AJDungate :)

@ycombinator Who bullied them into doing this 😭

After hearing feedback from Canadian founders in our network, we’ve decided to add Canada back to our list of accepted countries of incorporation. Going forward, YC will once again invest in US, Canada, Cayman, and Singapore corporations. ycombinator.com/blog/adding-ca…

Interesting perspective. Reminds me vaguely of GNN analysis. I wonder if there are challenges similar to over-smoothing, over-squashing, etc

Things like this make it more and more practical github.com/tobi/qmd No more fragmentation across 10 different platforms!

I think the answer is going to be markdown. All of our systems will just end up being markdown files, whether or not they are hosted on some fancy platform like Notion. Markdown from top to bottom, and claude can touch everything.

@risos8200 Project Hail Mary is an awesome The Martian-like read, courtesy of @MattLeighton5. Also good for 2026: big space year!

holiday tech detox reading list, anyone got any other recommendations?

@skyler_chan_ @gru_space @ycombinator 2026 is going to be the best space year of our lives
