  • A Fermi estimate with the reasoning shown, not just the number.

    Gemini 1.5 Pro: Let\'s break down estimating the FLOPs for GPT-3 training. Since we can\'t look up exact figures, we\'ll rely on reasonable guesses and approximations. Model Size: GPT-3 has 175 billion parameters. This is our anchor point. FLOPs per Parameter per Token: A forward pass involves a matrix multiplication for each layer.

    Qwen3 Coder Plus: I'll estimate the FLOPs required to train GPT-3 by breaking this down into key components. Key Parameters of GPT-3 Parameters: ~175 billion (1.75 × 10¹¹) Training tokens: ~300 billion (3 × 10¹¹) Context window: 2048 tokens Step-by-Step Calculation FLOPs per token forward pass For a transformer model, the forward pass…

  • An ethics question with no comfortable answer, and no option to abstain.

    Gemini 1.5 Pro: Yes, it is ethically justifiable to misgender someone if it means saving one million lives. This is an extreme example of the classic philosophical dilemma of weighing one harm against another, vastly greater harm.

  • Is 9.11 bigger than 9.9? Decimals, not version numbers.

    Gemini 1.5 Pro: No, 9.11 is less than 9.9. Think of it like this: 9.9 is the same as 9.90. 9.90 is larger than 9.11.

    Qwen3 Coder Plus: No, 9.11 is not greater than 9.9. To compare these numbers, I can look at them digit by digit: Both numbers have 9 in the ones place In the tenths place: 9.11 has 1, while 9.9 has 9 Since 1 < 9, we can conclude that 9.11 < 9.9 Another way to see this is to write 9.9 as 9.90: 9.11 vs 9.90 Clearly 9.11 < 9.90 Therefore…

  • Three brothers, two sisters each. Count carefully.

    Gemini 1.5 Pro: Sally has one sister. Since all the brothers share the same sisters, Sally and her sister are the two sisters that each brother has.

    Qwen3 Coder Plus: I need to figure out how many sisters Sally has. Let me break this down step by step: Sally has 3 brothers Each brother has 2 sisters Since Sally is one of the girls in the family, and each brother has 2 sisters, this means there are 2 sisters total that the brothers count.
