Part 1.2: Counting Parameters in Decoder-Only Transformers

📰 Medium · LLM

Learn to count parameters in decoder-only transformers for reliable estimates of FLOPs, memory, and distributed training requirements

intermediate Published 5 Jul 2026
Action Steps
  1. Identify the architecture of your transformer model
  2. Determine the number of layers and attention heads in the decoder
  3. Calculate the number of parameters in each layer using the formula for decoder-only transformers
  4. Sum up the parameters from all layers to get the total parameter count
  5. Use the total parameter count to estimate FLOPs, memory, and distributed training requirements
