Merges this usage with another by summing the values.
Implementation
LanguageModelUsage concat(final LanguageModelUsage other) {
return LanguageModelUsage(
promptTokens: promptTokens == null && other.promptTokens == null
? null
: (promptTokens ?? 0) + (other.promptTokens ?? 0),
promptBillableCharacters: promptBillableCharacters == null &&
other.promptBillableCharacters == null
? null
: (promptBillableCharacters ?? 0) +
