Estimating the Theoretical Parameter Capacity of a Hypothetical GPT-6-Class Model [D]

I've been exploring a hypothetical question: How large could a model's parameter count be if a major AI provider allocated a substantial GPU cluster to inference while targeting 66 output tokens per second per active user?

Key points

  • Estimating the Theoretical Parameter Capacity of a Hypothetical GPT-6-Class Model
  • GPU resources: 800,000 H100-equivalent GPUs available across the broader infrastructure.
  • Weight format: FP8, approximately one byte per parameter.
  • If 30% of the assumed GPU pool were allocated to inference:
