Thanks for putting to this together.
I have a suggested modification. You are mixing references in your document.
Re: '~$1 million: Cost to train a 13 billion parameter model on 1.4 trillion tokens The LLaMa paper mentions it took them 21 days to train LLaMa using 2048 GPUs A100 80GB GPUs.'
The LLaMA-13B model took 2.75 days of 2048xA100 (135,168 GPU-hours) with 1 trillion tokens. The 21 days for 1.4 trillion was for LLaMA-65B.
I would suggest using the LLaMa-13B numbers since those are the most relevant for this section, or at least modify "21 days to train LLaMa" to "21 days to train LLaMa-65B" for clarity.
