llm.c by Hand✍️ C programming + matrix multiplication by hand This combination is perhaps as low as we can get to explain how the Transformer works. Special thanks to Andrej Karpathy for encouraging early feedback and tetsuo //: 👾 for helping me understand the pragma magic. I hope this... show more

@karpathy @7etsuo Awesome! Looking forward to an llm.c Attention episode

@karpathy @7etsuo This is a great suggestion! Thanks!

@karpathy @7etsuo Is there a way to load a single layer of a LLM (in example Llama3-70B) and process it layer by layer so it fits on a normal PC memory ? Could you explain how to do it ?

Tom Yeh2 years ago

@karpathy @7etsuo It is possible. But it would be quite slow. To generate each token, the model has to evaluate every one of the hundreds of layers. Say loading each layer takes 1 second. It would take 100 seconds to load 100 layers for one token. Then you multiple that by 1000 tokens. Very slow.

@karpathy @7etsuo Can these be made into the notebooks!? That would be awesome.

@karpathy @7etsuo I am waiting for a notebook ninja to step up to help.😄

We all smoke our way, for now I have mastered the art of the glass tip cone style. It’s not a specialty roll by any means, but it’s consistent for me. I don’t have the fine hand coordination nor the patience to fuck up a hand roll when I can do this pretty easily and it smokes as proper as a good hand roll. When I have more time away from serving, I’ll practice hand rolling but this is how I smoke.

It’s hard to post this cruelty, this hate, this evil, as it makes me so angry - but it needs to be seen. We need to show what Trump is doing to our people. We are fighting Trump and ICE by getting into the hands of as many immigrants and allies as possible. As well as lawful and constitutional immigration advice, PAXIS can help people prepare for conflict, and can help defuse situations. FIGHT ICE, FIGHT TRUMP, FIGHT FASCISM:

The London promise is simple. If you work hard, and get a helping hand, you can achieve anything. That's why I'm running again as Mayor: so City Hall can continue to be that helping hand for every Londoner.
