How to use

model: "deepseek/deepseek-r1-0528"

Cap quality here and save

Hard questions go to this model, easy ones drop to something cheaper. Set a savings target (0–0.8) and the router tunes itself until realized savings converge on it.

{
  "model": "celon/auto",
  "celon": {
    "anchor": "deepseek/deepseek-r1-0528",
    "savings_target": 0.4
  }
}

Naming a model directly gets you that model — savings controls don't apply.
