@semidoped @vikramskr fun episode. it was really technically dense. definitely would need to rewatch.

A masterclass on Google's TPU v8 Networking.
Two TPU chips? Pssh. We already knew workload-specific silicon was here.
But two scale-up networking topologies?
That's the actual Google TPU news.
Workload-specific interconnects. Think about that.
New Semi Doped with @vikramskr and @austinsemis.
Copper? Yep. Optics? Yep.
What we cover:
- TPU splits in two: 8t training, 8i inference.
- Virgo: 47 Pb/s scale-out fabric, 100% OCS.
- Boardfly scale-up: copper PCB + AECs inside racks, OCS between groups. 16 hops → 7.
- Training uses 3D torus (Rubik's Cube).
- Inference doesn't. Workload-specific topologies now.
- Dragonfly traces to a 2008 paper by Kim, Dally, Scott, Abts. Abts went on to build Groq's interconnect before Nvidia.

Hiring 1,000 new grad builders — because emerging AI talent is the experienced AI talent. Technical foundation required. Builder mindset non-negotiable. ⬇️

I’m locked on, @DavidSacks! We’re hiring 1,000 new grads & interns right now to ride the AI exponential. You are right they said AI would kill entry-level jobs. Meanwhile these grads & interns are building it — powering Agentforce & Headless360 at Salesforce. 🚀 New grads: Drop your resume to @salesforcejobs or futureforce@salesforce.com #FutureForce #AI

Narrative violation: Hiring of new college graduates is up 5.6% over last year. Youth unemployment for degreed 20–24‑year‑olds fell to 5.3% from 8.9%. Weren’t we told that 50% of entry-level jobs were going away?

China keep distilling those fucking models thank you for the hard work I salute you 🫡

A Chinese company facing chip restrictions can train this
But xAI can’t even get SOTA
With a million H100 equivalents

Funniest part about this is xai has had access to a significantly larger compute pool and can't seem to train anything decent to save their lives

GPT-5.5 was trained on a 100k GB200 cluster probably the Stargate in Abilene Texas with 2 out of 8 completed buildings and ~112k operational GPUs

He wanted to show the world what an intelligent black man looked like.
Many whites didn’t believe he authored his writings and he understood the link b/w racial intelligence and aesthetics in western society. This is why his portraits all emphasize his head. He was playing on assumptions in ethnology and phrenology.
The fact be did this despite being a fugitive makes it a bigger statement imo.

Today we're announcing LevelUp: a free, four-week training program that takes people with no prior experience and prepares them to work as fiber technicians on data center construction sites across the US.
We built this program with CBRE because the fiber technician field, and the broader construction industry, is facing a nationwide shortage at a time when data center demand is higher than ever.
How it works:
🔧 Classroom instruction, hands-on labs + team activities covering transferable technical skills
🎓 Graduates have the opportunity to work at Meta's US construction sites through our contractor network
🤝 Open to everyone from recent high school grads to mid-career professionals
Since 2010, Meta's data center projects have supported 30,000+ skilled trade jobs during construction + 5,000+ permanent operational roles. LevelUp is about building the pipeline to keep that going.

but what if we made an LLM from scratch?
Reese Chong@_reesechong
Behind the scenes of mni-ml: January 4th 2026 - my roommate @MankyDankyBanky and I wanted to do a big project together. ”maybe we should try to build pytorch from scratch” We found @srush_nlp's minitorch curriculum and committed to grinding through it Jan to April. February - autodiff and tensor internals done. lots of late night PR reviews, stacked diffs, Kinton ramen runs to Toronto when I'd visit Aadi at Shopify. We started posting on X to keep ourselves accountable. March - the month of parallelization: Aadi shipped tiled matmul using the same algo @nvidia teaches in their CUDA guide, wrapped by end of month - pooling, conv1d/2d forward+backward, softmax, dropout. March 22-23 — @socraticainfo symposium & we see the tinytpu team on the stage which filled us with determination 🫡 cc: @evanliin @XanderChin @suryasure05 @kennykgguo March 24 - chose the mni-ml brand and started the educational blog March 30 - minitorch is DONE ahead of schedule. now we build on top of the framework. April 5-6 - cuBLAS matmul via koffi FFI. buffer pooling, strided batched GEMM, kernel optimizations. CUDA backend takes shape. April 7 - huge day. cross-platform CI pipeline, prebuilt npm binaries, v0.3.0 — CUDA live on @npmjs. flatten the monorepo, add @WebGPU + Windows CUDA build targets by eod. April 12 - flash attention CUDA kernel ships. we caught a bug where head dim > 32 was truncating. April 14 (during exam season), we recorded the demo in @Shopify recording studio during Aadi’s lunch break. Everything over the last 4mo finally came together. Cc: @fnthawar @tobi @alspee April 17: launch post and bought the domain mni.ml and we’re just getting started. We have so much in store for this summer, stay tuned 🫡 cc: @sundeep @GavinSherry
