What the efficiency score measures
Each AI project gets a score from 0–100 reflecting how efficiently it uses tokens. The score factors in:- Token waste from repeated or failed requests
- Prompt-to-completion ratio vs benchmarks
- Cost per unit of output vs similar workloads
- Cache hit rate (for providers that support prompt caching)
How to use it
Improving a low score
A low efficiency score usually points to one of three root causes:- Prompt bloat — prompts that are longer than they need to be
- High retry rates — requests failing and being retried at full cost
- No caching — identical or near-identical prompts being sent repeatedly without prompt caching
