How much does it cost to run an AI agent?

Costs depend on the model, tokens per task, and volume. A simple agent using GPT-4o might cost $0.01-0.05 per task. Complex multi-step agents with tool calls can cost $0.10-1.00+ per task. Monthly costs for production deployments typically range from $50 to $5,000+ depending on scale.

What factors affect AI agent costs the most?

The biggest cost drivers are: model choice (GPT-4o vs Claude vs open-source), tokens per interaction (longer contexts cost more), number of tool calls per task (each call requires additional model invocations), and total request volume. Optimizing prompt length and caching can reduce costs significantly.

Detailed Breakdown

Model	Provider	Cost / Task	Daily	Monthly	Yearly
Claude Sonnet 4	Anthropic	$0.04	$10.50	$231.00	$2,772.00

How it's calculated: Cost per task = (input tokens / 1M x input price) + (output tokens / 1M x output price). Daily = per task x tasks per day x agents. Monthly = daily x days per month. Yearly = monthly x 12. All prices are per-API pricing and may differ from subscription plans. Cached token discounts and batch pricing not included.
