n8n AI agents: how many tokens per task, and what does it cost?

n8n AI agents uses 137K tokens per task and costs $0.42 per task. AgentBurn snapshot 2026-10-27. Every figure carries a provenance label: source-backed, derived, or left empty when no public basis exists.

What it is. Workflow automation platform where LLM agents call real integrations

n8n lets teams build agent workflows as node graphs: an LLM node reasons over incoming events, calls HTTP and database nodes, and branches on the result, with the full execution trace kept per run. It is self-hostable, so the marginal cost of a run is the model tokens plus the workflow's own overhead.

What each number is based on

AgentBurn labels every field. Source-backed means the cited page states the figure; derived means a formula on this page produced it; not published means no public basis exists and the field is left empty rather than estimated.

Field	Basis	Note
tokensPerTask	Source-backed	GitHub issue — instance AI assistant: ~137k input tokens for a five-word question.
costPerTaskUsd	Source-backed	Same reported run: $0.42 total cost.
successRatePct	Not published	Single anecdotal run; no success-rate measurement.
runsPerDay	Model estimate	No public source publishes daily run volume; this is a model estimate from pricing tiers and community reports, shown only in estimated-volume context.
