 ### New features
 
+* `Chat`'s `.tokens()` method gains a `values` argument. Set it to `"discrete"` to get a result that can be summed to determine the token cost of submitting the current turns. The default (`"cumulative"`), remains the same (the result can be summed to determine the overall token cost of the conversation).

 ### Bug fixes
 
 * `ChatOllama` no longer fails when a `OPENAI_API_KEY` environment variable is not set.
