How it is calculated
- The indexes (overall, reasoning, coding) are the ones LLM Stats publishes; Codifly does not run these tests.
- Prices are each provider's official standard API prices, without caching or batching.
- The blended price weighs 3 input tokens per output token; cost-benefit divides the overall index by that price.
