Overview
Repeated prefixes can be cached, repeated questions can be answered from your own cache, and rate limits will find you eventually — so retry with backoff.
What this lesson covers
- Cache stable prompt prefixes to cut cost
- Retry with exponential backoff on rate limits
- Queue or shed load instead of failing hard
