Beware the Agent Token Trap: $88k Monthly Bill for 35 People

The author shares a real-world AI Agent cost disaster: a team of 35 engineers received a staggering $88,000 bill after using Agents for a month.
The cause: An agent is a continuous loop. Unlike a single-turn chatbot, an agent resends the entire accumulated context at every reasoning step (like tool calls, file reads, validation checks). By step 20, you've essentially paid for the same system prompt 20 times.
Solutions:
- Model tiered routing: Route 85% of simple daily tasks to cheaper, faster models, reserving frontier LLMs only for complex, core tasks.
- Context pruning.
- Set budget caps: For example, a $100 daily cap per developer.
The author emphasizes that whether building an in-house routing layer or using tools like Orqai, a sound cost-control architecture is the key to deploying Agents successfully.
