Cost

Cost data is shown on the Overview dashboard (/dashboard). There is no separate cost page - spend information is surfaced directly alongside your other agent metrics.

Cost chart

The overview includes a daily bar chart showing total LLM spend over the last 30 days. Hover over any bar to see the exact amount for that day.

Cost by agent

Use the agent list to find expensive agents, then open an individual agent page to see its cumulative cost across recorded sessions.

How cost is calculated

Cost is computed from the token counts and model pricing reported by your LLM provider. For each LLM call:

cost = (prompt_tokens / 1000 * input_price) + (completion_tokens / 1000 * output_price)

Costs are aggregated at the session level and then at the agent level.

Cost anomaly alerts

If a single session costs more than $1.00, Maev classifies it as a Cost anomaly with high severity. Sessions over $5.00 are classified as critical. You will receive an alert when a cost anomaly is detected.

Reducing cost

Common causes of unexpected cost:

• Infinite loops: the agent keeps calling the same LLM API repeatedly
• Oversized prompts: the system prompt or context window is growing unboundedly
• Wrong model selection: using a large model for a task that a smaller one can handle

Check the Sessions page to see if cost anomalies are recurring across multiple sessions for the same agent.
