     - We fixed a bug where `max_tokens` defaults were not properly being respected - `max_tokens` now correctly defaults to `256` as displayed on the model pages. Users relying on the previous behaviour may observe this as a breaking change. If you want to generate more tokens, please set the `max_tokens` parameter to what you need.
