llm.c by hand ✍️ C meets Transformer

This combination is perhaps as low as we can get to explain how the Transformer works.

Special thanks to @Andrej Karpathy

--

Part 1: gpt2_forward

Karpathy's llm.c implements the transformer forward step as the following sequence.

(skip)layernorm_forward
1. matmul_forward
2. attention_forward
3. matmul_forward
(skip) residual_forward
(skip) layernorm_forward
4. matmul_forward
5. gelu_forward
6. matmul_forward
(skip)residual_forward

Part 2: matmul_forward

B: Batches (of Tokens)
T: Tokens
C: Input Channels
OC: Output Channels

C programming and matrix multiplication are two of the most important topics. But it is often difficult to get people excited by these topics.

I hope this exercise can help people see further into the LLM black box, and appreciate C programming and matrix multiplication by hand. 😀

@British_Airways This is ridiculous. @British_Airways @HeathrowAirport.
It’s been a 10hr+ flight to LHR. Now stuck on a plane for 1hr 45 mins as you can’t park the plane due to fuel & logistic errors. Finally you get somewhere for us to park & you stop the plane too soon! #stillstuckonaplane

[RepresentAI @representAIreal]

@British_Airways @HeathrowAirport - we are stuck on a plane. It’s not ok to make people wait for 1.15 hr on top of a 10/11 hour flight when this could have been avoided if you’d checked all the fuel and logistics properly. I was also charged 13k for this flight! Shameful.

[RepresentAI @representAIreal]

@British_Airways We landed nearly 1.5 hrs ago. You should just let us off the plane or at least give us food/ refreshments/ further updates or a refund! If it gets to 2 hours of waiting on the tarmac that means 1/5 of my whole journey time as been stuck on tarmac on the ground - not flying!

Acquisition of Slack by Salesforce -- makes total sense for both parties, and they're both good companies. BUT ... this whole trend toward centralized oligopolization of tech (as tech's criticality/reach increases) ... there's only one word for it ... https://t.co/gaxQLSgynN
