How far did the archived GPT-4-class inference price fall?

In the archived survey through 2026-04, the lowest tracked model matching original-GPT-4 quality was DeepSeek V4 Flash at $0.18 per million tokens blended 3:1 — −99.5% versus GPT-4 at launch ($37.50 blended, Mar 2023). These are historical list prices, not a current lowest-price claim: batch endpoints run about 50% off and cached input about 90% off.
