The round

Work through short questions on FP16, BF16, FP8 and INT8. The round connects what each format can represent to the scaling and parameter-state choices used in training. You will explain mechanisms and perform calculations under the conventions given in each question.

What you'll practise

  • Range and precision

    Compare number formats and explain what their bit layouts mean for stored values.

  • Training stability

    Reason about loss scaling, overflow and higher-precision parameter state.

  • Quantization scales

    Calculate and interpret scales, including the effect of values outside the calibrated range.
