 "page_title": "How to compare harnesses on cost and latency for one task with Harnessrouter",
 "summary": "Run the same task on several harness and model pairs and pick the cheapest or fastest one.",
 "who": "A product lead choosing a harness and model for a feature and needing cost and speed data.",
 "problem": "The lowest-cost and fastest harness setup changes by task, so guessing wastes money or adds latency.",
 "outcome": "You get a side-by-side view of how each harness and model pair handled the same task.",
 "steps": [
  "Complete setup and connect at least one provider under Bring Your Own Key",
  "Open Agent harnesses in the Console and choose a supported harness",
  "Select New task, pick a model, and give every configuration the same task text",
  "Review the live progress and the files each run produces",
  "Read the methodology at https://harnessrouter.ai/benchmarks before drawing conclusions"
 ],
 "agent_prompt": "Using the HarnessRouter repo at https://github.com/HarnessRouter/harnessrouter, run the same task <task-description> on two harness and model pairs in the Console. Expected output: a short table of which pair was faster and which produced the cheaper run. Verify that both runs used the same task text before reporting the comparison.",

 "difficulty": "Intermediate",
 "time": "60 minutes",
 "basis": "readme",
 "caveat": "The README says the fastest and lowest-cost configurations vary by task, so one run does not show which setup is best for other tasks.",
