Insights
Value trends
Price deltas use weekly OpenRouter list prices (up to 6 months, or since the model launched). Value scores hold the latest Artificial Analysis indexes constant instead of guessing at historical benchmark numbers.
Value improvers
Biggest gains in value score over 90 days. Benchmarks are held constant, so a gain here means the price came down.
Regressions
Biggest 90-day declines in value score — usually a price increase on a model whose benchmarks haven't moved.
