Control Cost
Track cost before it surprises you. Repeated context, oversized prompts and using a large model for simple work are common cost drivers.
Goal: Create a simple cost model30 minOutput: Cost worksheet
- Cache stable instructions and reusable context.
- Summarize long context before sending it repeatedly.
- Use smaller models for simple classification tasks.
- Batch offline work where real-time responses are not required.
Estimate daily cost for your mini assistant at 10, 100 and 1,000 users.
Create a cost table and identify one change that reduces cost without reducing the required quality.
