I am so hopeful that 50 years from now we will look back on today's immunology treatments the way today we look at, like, lobotomies -- people who were hopefully trying their best but had astonishingly poor tools at their disposal.

Any time I don’t understand a line in Shakespeare, I just assume it’s a dirty joke and think up my own (bonus points if it fits the scansion)

If you're wondering whether or not to get a flu shot, I didn't get one in time, and I just had a fever dream where I was in the Drew Carey Show because several days ago I was on the Wikipedia page for the Drew Carey Show. You don't have to do this to yourself.

FTF, Carnegie Mellon. I’m sure it’ll livestream and have a hyperactive slack as usual.

Karpathy: nanochat

A small training+inference pipeline for creating your own LLM from scratch

$100 will get you a somewhat functional model

$1000 is more coherent & solves math

Excited to release new repo: nanochat! (it's among the most unhinged I've written).
Unlike my earlier similar repo nanoGPT which only covered pretraining, nanochat is a minimal, from scratch, full-stack training/inference pipeline of a simple ChatGPT clone in a single, dependency-minimal codebase. You boot up a cloud GPU box, run a single script and in as little as 4 hours later you can talk to your own LLM in a ChatGPT-like web Ul.
It weighs ~8,000 lines of imo quite clean code to:
- Train the tokenizer using a new Rust implementation
- Pretrain a Transformer LLM on FineWeb, evaluate CORE score across a number of metrics
- Midtrain on user-assistant conversations from SmolTalk, multiple choice questions, tool use.
- SFT, evaluate the chat model on world knowledge multiple choice (ARC-E/C, MMLU), math (GSM8K), code (HumanEval)
- RL the model optionally on GSM8K with
IPDDOI - RL the model optionally on GSM8K with
"GRPO"
- Efficient inference the model in an Engine with
KV cache, simple prefill/ decode, tool use (Python interpreter in a lightweight sandbox), talk to it over CLI or ChatGPT-like WebUl.
- Write a single markdown report card, summarizing and gamifying the whole thing.
Even for as low as ~$100 in cost (~4 hours on an
8XH100 node), you can train a little ChatGPT clone that you can kind of talk to, and which can write stories/poems, answer simple questions.
About ~12 hours surpasses GPT-2 CORE metric.
As you further scale up towards ~$1000 (~41.6 hours of training), it quickly becomes a lot more coherent and can solve simple math/code problems and take multiple choice tests. E.g. a depth 30 model trained for 24 hours (this is about equal to FLOPs of GPT-3 Small 125M and 1/1000th of GPT-3) gets into 40s on MMLU and
70s on ARC-Easy, 20s on GSM8K, etc.
My goal is to get the full "strong baseline" stack into one cohesive, minimal, readable, hackable, maximally forkable repo. nanochat will be the capstone project of LLM101n (which is still being developed). I think it also has potential to grow developed). I think it also has potential to grow into a research harness, or a benchmark, similar to nanoGPT before it. It is by no means finished, tuned or optimized (actually I think there's likely quite a bit of low-hanging fruit), but I think it's at a place where the overall skeleton is ok enough that it can go up on GitHub where all the parts of it can be improved.
Link to repo and a detailed walkthrough of the nanochat speedrun is in the reply.

I don't think they should copy it exactly, but I'd love to see Alex Winter and Keanu Reeves do a take on the tourist photos from when Sirs Patrick Stewart and Ian McKellen did Waiting for Godot in NYC.
Sirs Patrick Stewart and Ian McKellen, both wearing bowler hats, on the Wonder Wheel. McKellen has his arms around Stewart, and a terrified look on his face. Stewart is grinning. Sirs Patrick Stewart and Ian McKellen, both wearing bowler hats, holding hands on the boardwalk. Sirs Patrick Stewart and Ian McKellen, both wearing bowler hats, jogging over the Brooklyn Bridge.

Chicago priest Fr. Larry Dowling describes procession to ICE facility: “No one had the courage to speak directly to us. No one from Homeland Security could stand in the presence of the Monstrance holding the Blessed Sacrament. No wonder. Evil is repelled, recoils in the presence of Christ.”

We have armed secret police kidnapping people off the street based on the color of their skin.

When we win: we will haul them before a Senate committee. The masks will come off. There will be consequences.

Once we were driving somewhere, and I was reading in the passenger seat, and said something about how I totally can’t hear music when I’m doing anything else so i had no idea what my husband had been playing, and he was like yeah but you’ve been singing along for half an hour

So. Could be anything
