View Source

Configuration for the evaluation framework.

Configuration can be set via:

  • Application environment
  • Environment variables
  • Explicit options passed to functions

Application Configuration

config :nous, Nous.Eval,
  default_model: "lmstudio:ministral-3-14b-reasoning",
  default_timeout: 30_000,
  parallelism: 4,
  results_path: "priv/eval_results"

Environment Variables

NOUS_EVAL_DEFAULT_MODEL=lmstudio:model
NOUS_EVAL_DEFAULT_TIMEOUT=60000

Cost Configuration

Provider pricing for cost estimation (per 1K tokens):

config :nous, Nous.Eval,
  cost_config: %{
    "lmstudio" => %{input: 0.0, output: 0.0},
    "openai" => %{input: 0.01, output: 0.03},
    "anthropic" => %{input: 0.015, output: 0.075}
  }
