# `Minga.RenderModel.UI.AgentChat.Usage`
[🔗](https://github.com/jsmestad/minga/blob/main/lib/minga/render_model/ui/agent_chat.ex#L208)

Pre-resolved core view of a turn-usage message.

The editor builder copies the numeric fields out of the agent's turn-usage
struct into this core view so the GUI encoder serializes plain numbers.

# `t`

```elixir
@type t() :: %Minga.RenderModel.UI.AgentChat.Usage{
  cache_read: non_neg_integer(),
  cache_write: non_neg_integer(),
  cost: float(),
  input: non_neg_integer(),
  output: non_neg_integer()
}
```
