Inside the $4,000 monthly budget, at 28% of it.
Where the money goes, per request
- Prefix (handbook + role) $0.02
- Variable input $0.00056
- Output $0.00335
Caching moves the prefix from full rate to 0.1x on every request after the first. Turn caching off and watch the blue segment take over the bar.
The exercises behind this are in Lab 5, prompt caching and cost. For the budget in context, see the scenario.
