Budget Strategy
Set Daily Caps, Not Just Monthly
A runaway agent can burn your monthly budget in a single day. Set daily caps at 1/25th of your monthly budget (accounting for weekends).
Monthly budget: $2,500 Daily cap: $100 (with auto-stop) Alert at: $50 (50%), $80 (80%), $100 (100% → auto-stop)
Budget Per Project
Don't use a single org-wide budget. Create per-project budgets so a spike in one project doesn't affect others.
Include a Buffer
Set your operational budget at 80% of your actual budget. The 20% buffer absorbs traffic spikes without triggering auto-stop.
Model Selection
The 80/20 Rule
80% of your requests probably work fine with the cheapest model. Identify the 20% that need premium models and route accordingly.
Benchmark Before Switching
Before migrating from GPT-4o to GPT-4o-mini:
Consider Latency
Cheaper models are usually faster. GPT-4o-mini is 3-5x faster than GPT-4o. For user-facing applications, this speed improvement is a bonus on top of the cost savings.
Prompt Optimization
Compress System Prompts
Audit every system prompt quarterly. Common bloat sources:
Use Structured Output
Request JSON responses when you need structured data. This reduces output tokens and makes parsing reliable:
Instead of: "Analyze this text and tell me the sentiment, key topics, and a summary."
Use: "Return JSON: { sentiment: positive|negative|neutral, topics: string[], summary: string (max 50 words) }"
Cache Repeated Prompts
If the same prompt produces the same output, cache it. Common candidates:
Team Attribution
Tag Everything
Use metadata tags consistently across your organization:
project: "customer-support" feature: "ticket-summary" team: "support-engineering" environment: "production" userId: "user_123"
