# `Nous.Eval.Metrics.Summary`
[🔗](https://github.com/nyo16/nous/blob/v0.17.1/lib/nous/eval/metrics.ex#L165)

Aggregated metrics summary across multiple evaluation runs.

# `t`

```elixir
@type t() :: %Nous.Eval.Metrics.Summary{
  count: non_neg_integer(),
  fail_count: non_neg_integer(),
  max_score: float(),
  mean_cost_per_run: float() | nil,
  mean_latency_ms: float(),
  mean_score: float(),
  mean_tokens: float(),
  min_score: float(),
  p50_latency_ms: non_neg_integer(),
  p50_tokens: non_neg_integer(),
  p95_latency_ms: non_neg_integer(),
  p95_tokens: non_neg_integer(),
  p99_latency_ms: non_neg_integer(),
  p99_tokens: non_neg_integer(),
  pass_count: non_neg_integer(),
  pass_rate: float(),
  tool_call_distribution: %{required(String.t()) => non_neg_integer()},
  tool_error_rate: float(),
  total_estimated_cost: float() | nil,
  total_tokens: non_neg_integer(),
  total_tool_calls: non_neg_integer()
}
```

# `compare`

```elixir
@spec compare(t(), t()) :: map()
```

Compare two summaries.

# `from_metrics`

```elixir
@spec from_metrics([Nous.Eval.Metrics.t()], [float()]) :: t()
```

Create a summary from a list of metrics and scores.
