How a Multi-Agent Setup Tripled LLM Costs
Towards Data Science
EDITOR BRIEF
A move to a multi-agent architecture caused LLM token costs to rise to about three times what was expected. The article says the increase was quiet at first and explains that changes were needed to fix the problem.
INSIGHTS
If you're building AI apps, architecture choices can change cost fast. A good next step is to measure token usage early and compare simpler designs before adding more agents.
