LLMs keep getting bigger. Compute budgets, unfortunately, do not.
This fall @Stanford, we (@AnayMehrotra @gvelegkas and Amin Saberi) are teaching MS&E 319: Efficient Generative Language Models.
The course asks a simple question: given a modeling goal and a limited computational budget, how should we choose the training objective, model architecture, and inference algorithm?
We’ll cover some of the main ideas, and occasionally surprising tricks, that make large language models more efficient, including efficient pre-training, mixture-of-experts architectures, attention and KV-cache compression, quantization, speculative decoding, LoRA, RLHF, DPO, and distillation.
And no, “just buy more GPUs” will not be the only answer.
We’ll try to post all the lecture materials and recordings as the course unfolds.

After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI?
I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev
• 20-200x faster
• 40-400x cheaper (w/ output tokens free)
• Frontier composable intelligence optimized for decisions
AFAICT the shortest path to AI-based economic revolution

Large language models normally write one token at a time, each word waits on the one before it, which is slow and leaves the GPU mostly idle.
Speculative decoding flips that: a small, fast model guesses the next several tokens, and the big model checks them all in a single pass, keeping the good ones and correcting the rest.
In his talk at the 2025 edition of SysConf, Habeeb Shopeju (@HAKSOAT ), Senior ML Engineer at Autodesk Research, broke down this and the other tricks - KV caching, paged attention - that inference engines use to go faster.

Registration for SysConf 2026 is still open: events.ringcentral.com/event….
Register, spread the word, tell a friend, and we’ll see (or hear) you at #SysConf26!

A single OCR error almost killed a $1.7M energy infrastructure build for a Fortune 500 company powering AI data centers.
The code said T12C3.
OCR read 712C3.
False alerts cascaded. Pipeline nearly stopped.
This is why we built AwaitVerify. (1/5)

When people say “Triton is a compiler”, they mean something very specific.
Triton is not just another way to write Python that happens to use CUDA underneath, it is a real compiler stack for GPU kernels! 🧵

As hinted earlier, our next book club series kicks off this Sunday (Jan 11) with Designing Data-Intensive Applications (DDIA).
See you there 🚀 : discord.gg/hNdUgEKgQD

Your container does not have GPU drivers installed
So, how does PyTorch inside it actually use the host's GPU?
Let me explain 🧵

Unwrapping TPUs: A December Deep Dive 🎄
The last couple weeks have thrown TPUs into the spotlight, but honestly, they've been fascinating since way before that.
This December, @abiralxshakya and I are spending 31 days figuring out how TPUs actually work, sharing our daily learnings here. Well, figuring out is generous -- more like squinting at specs and bothering people who know better!

🗣️ @_enfinity rebuilt Kubernetes from scratch in Go
After teaching Kubernetes to thousands of engineers, this validates what I've seen: people don't struggle with complexity; they struggle with abstractions before fundamentals

We trained a 400M parameter model that outperforms Gemini at similarity search! @vectorpath_ai
Search should understand intent, not just keywords. So we trained a conversational search model that does exactly that.
A thread on why this matters & where search is heading 🧵👇

🚀 Huge milestone for VectorPath! Our SearchMap model just hit 1,000 downloads in 24 hours on @huggingface 🎉
We’re building the future of search — fast, conversational, intent-driven. If you’re curious, check it out and see the magic in action.
👇 Links in the thread!

🚀 Big news from @VectorPathAI! We just launched the research preview of SearchMap — our conversational search embedding model, and it’s already taking off with 120+ downloads on @huggingface in just 2 days!
Here’s why we think this changes the game for search. 🧵👇

Replying to @saintmalik_
If you don’t want anything secret don’t compile it in an app, that’s being said you can always use Remote config but that comes with its own issues, or you can fetch the keys through a public Key exchange

Hey all, I've got really exciting news.
I, @IamDavidOnuh, @HAKSOAT , @Lord__Sarcastic, @SLKhadeeja have been working on Ahnlich, an *In-memory vector database* in Rust.
