Key Insights

  • Cost varies 1000x: From $0.0008 to $0.12 per conversation
  • Context ≠ Cost: Larger context doesn't always mean higher price
  • O(n²) scaling: Processing time increases quadratically with context length
  • O(n log n) scaling: Near-linear growth enables 100x larger contexts
  • Practical limit: Most models become unusable beyond 200k tokens due to latency
  • Sparse advantage: 10M tokens with sparse attention = faster than 128k with standard
