Open Router Pricing History
How this data is calculated:
This chart shows percentage changes over time for Open Router endpoints that experienced pricing changes. Each line represents a model:metric pair (e.g., "anthropic:claude-3-5-sonnet (pricing_prompt)") where the price has changed at least once since first recorded. The percentage change is calculated as ((current_price - original_price) / original_price) × 100, so a value of +100% means the price doubled, while -50% means it halved. Only endpoints with multiple unique prices are included to focus on meaningful changes.
