Optimus Alpha: Here are 5 jokes: Why did the scarecrow win an award? Because he was outstanding in his field! Why don't scientists trust atoms? Because they make up everything!

A Fermi estimate with the reasoning shown, not just the number.
Laguna XS 2.1 (free): To estimate the total number of FLOPs required to train GPT-3, we use a standard formula for large language models: Total FLOPs ≈ 6 × Parameters × Tokens Step-by-Step Reasoning: Parameters: GPT-3 has 175 billion parameters (175 × 10⁹). Tokens: The model was trained on 300 billion tokens (3 × 10¹¹).
Optimus Alpha: Let's walk through an estimation of how many FLOPs were required to train GPT-3, using only reasoning and not searching for the exact numbers. Step 1: Understand Model Size GPT-3 (the original) had 175 billion parameters.
Satire, one line long, about AI taking over an industry nobody saw coming.
