During this update, we upgraded the model responsible for text interactions on the free server. To be upfront about it: we're still observing how the new model performs over time — if you pay close attention, you may notice subtle changes in writing style. Dev Neko will be monitoring feedback closely and making adjustments as needed.
This change only affects users on the free server (i.e. the default API). Users who have brought their own API key are completely unaffected.
