This guy doesn't have any idea what he is talking about. He consistently posts such bullshit on twitter. Mostly copy paste with added spice mix.
For instance - MoE yes, but 16 experts at 111B parameters? Doesn't make sense. GPT 3 had 175B parameters. I doubt they would go less on base models from now on. The number that makes more sense is ~220B parameters per model and 8 expert models. That is the same inference cost in total.
The 13T tokens of training data seems pulled from thin air.
