two of the products we tested — Huel's Black Edition meal replacement powder and Naked Nutrition's vegan mass gainer — had enough lead that our experts caution against using them at all

a single serving of these protein powders contained between 1,200 and 1,600% of CR’s level of concern for lead

Two plant-based protein powders contained enough lead that our experts advise against consuming them. Naked Nutrition’s Mass Gainer powder contained 7.7 micrograms of lead per serving, which is roughly 1,570 percent of CR’s level of concern for the heavy metal. One serving of Huel’s Black Edition powder contained 6.3 micrograms of lead, or about 1,290 percent of CR’s daily lead limit.

Two other powders contained lead between 400 and 600 percent of CR’s level of concern: Garden of Life’s Sport Organic Plant-Based Protein and Momentous’ 100% Plant Protein. Consumers should limit these to once a week, Akinleye says. (See company responses below.)

The only non-plant-based protein powder with lead detected at over 200 percent of CR’s level of concern was MuscleMeds’ Carnivor Mass powder. Six additional plant-based powders, five dairy-based powders and shakes, and one beef powder contained lead above CR’s level of concern.

We also found measurable levels of cadmium and inorganic arsenic in some products. One serving of Huel’s Black Edition plant-based protein powder contained 9.2 micrograms of cadmium, more than double the level that public health authorities and CR’s experts say may be harmful to have daily, which is 4.1 micrograms.

Another plant-based option, Vega’s Premium Sport powder, had enough cadmium that one serving would also put you just over that level. In one dairy-based product, Optimum Nutrition’s Serious Mass whey protein powder, we also detected 8.5 micrograms per serving of inorganic arsenic, which is twice the limit of what our scientists say is safe to consume daily.

Yikes! I would not do this because I am allergic to some fragrances, and not sure which they are, so all of them make me anxious. Being betrayed by a book would be so distressing. Are people doing this?!

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.

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.

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

detailed walkthrough: github.com/karpathy/nan...

repo: github.com/karpathy/nan...

Andrej Karpathy & @karpathy

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.

Government workers 👇🏾

Lunch is on the house:

Being in the heart of downtown DC, we love that so many of our Federal employees stop by during lunch for a Donburi at China Chilcano or a Fútbol Club at Jaleo. And just because the government is shut down doesn't mean you have to miss out on your favorite lunch spot- because this time, its on us!
Join us for lunch from 11:30 AM to 3:00 PM at any of our participating restaurants and enjoy a free lunch item when you present your government ID-you heard that right! Dine in with us Monday through Friday and choose your favorite: a sandwich at Jaleo, a donburi at China Chilcano, a wrap or pita at Zaytinya, or a torta at Oyamel.
We've always believed in serving our community with open arms and good food-no shutdown can stop that.
