Unclear Where or how default_output_tokens is used once set is not stated.

What

The schema used to define model pricing and configuration for loop models now accepts an optional default_output_tokens field, in addition to the existing max_output_tokens field.

Why

Having a separate default, distinct from the maximum, suggests model configuration can now specify a typical output-token count to use in addition to the upper limit, though the finding does not say where this default is applied.
