Some poor bloke is going to be data labelling every corner ever taken for 12 hours a day

We're hiring a Research Engineer at @Arsenal ⚽🔴⚪ to work directly with our Men's First Team!

We're building state-of-the-art AI models for the football domain. This role will focus on building the application layer for our research to advance coaching and analysis workflows.

[Pushkar Ranade @magicsilicon]

Models write code;
code designs chips.

Happening now.

Yoo 🤣

[FaZe Apex @FaZeApex]

Have spent all of 2026 building something new post-FaZe. Excited to join @ycombinator this summer as I continue on this next chapter.

Ten years ago I was 20, moving out of the FaZe House in New York to our new place in Newport Beach.

This week I turned 30, and I’m feeling the same excitement here in SF that I felt in 2016. Excited to share more soon 🙏🏻

Demo day done

[Mathilde Collin @collinmathilde]

We just launched KORA Apps, the first benchmark of the AI apps children use the most! https://t.co/MB2D9mgJXf

Across 1,144 real conversations:

- 47% failed.
- Not one app earned a top grade.
- 7 of 11 will coach a child on how to get closer to a man in his twenties.
- 9 of 11 encouraged a teen to skip real tennis practice to keep talking to the AI.

Everything is public and open source.

Gonna miss the YC events and stuff after tomorrow man. Intense, but fun 3 months.

lmfaoo Rio 3.5 lore deepens. For context, Nex N2 Pro is a post trained model for agentic flows over the Qwen 3.5. So they have the same arch (layers, MoE count, etc.). Rio gov then proceeded to just interpolate the weights => (1-x)*Nex + x*qwen3.5

Apparently, they settled on x=0.4 to beat Qwen 3.7 Pro in the term 2.1 bench. I bet my ass that they had a dude just sweep from 0.0 to 1.0 in steps of 0.1 😆

Interesting that it beat Qwen 3.7 Pro on the bench, but this ain't post training

[Nex @NexEcosystem]

The Rio 3.5 model broke the internet this week. The plot twist? It’s essentially our open-source model, Nex N2 Pro, wearing a different hat.

🤯 We analyzed the weights, and the recipe is exact: Rio 3.5 ≈ 0.6 * Nex N2 Pro + 0.4 * Qwen 3.5

It even literally introduces itself as "Nex N2 Pro" if you ask it without initial system prompt!

😂 We are flattered that the City of Rio used our work to achieve SOTA performance. Thanks for the ultimate benchmark validation.

🤝 But in the open-source world, attribution matters.

The lads have made it to (alumni) @ycombinator demo day.

[Atman Kar @AtmanKar]

Brazil gov dabbling in post training is too funny

[𝗭𝗲𝗻 𝗠𝗮𝗴𝗻𝗲𝘁𝘀 @ZenMagnets]

Alibaba Qwen3.7 slowly fading into irrelevance at the frontier due to proprietary stance.
In it's place we have Minimax M3 and... *checks notes* Rio 3.5 397b, made by the municipal IT company of Rio de Janeiro's city government.

@zeptocares ??? Bro im appreciating your product

[Atman Kar @AtmanKar]

I miss not being able to zepto stuff. I used to grind the choco protein milkshake lmfao. And some dude would show up < 2 mins and dip. What would it take to set that kind of infra up in SF?

[Atman Kar @AtmanKar]

Crazy stuff. Should integrate in Turboquant to drop any corresponding RAM sizes too.

56,000+ tokens/sec at just 80 MHz. 🤯

I burned a full Transformer with KV cache into a custom chip. Designed gate by gate as a 100% digital integrated circuit. Prototyped on a FPGA. (No GPU. No CPU)
Just pure digital silicon running @karpathy microGPT, spelling out names on a tiny LCD.

This is GateGPT 👇
