The headline

The gap between the cheapest and most expensive models is now roughly 3,750×. At the cheap end, Llama 3.2 1B Instruct costs $0.0100 per million blended tokens; at the top, GPT-4 costs $37.50. For most production workloads the interesting question isn't “what's cheapest” but “what's the cheapest model that's smart enough” — which is exactly what our value leaderboard answers.

Since we began tracking, we’ve recorded 163 price changes — 102 drops vs 61 increases across 10 providers, plus 325 new models. The single biggest drop: Qwen3.5 Flash cached input down 93% on 10 August 2026.
