Model Versions

Each chat model carries a version. Name the one you want on every request, and your project stays on it until you say otherwise.

Version 2.1

chat-2.1-smart and chat-2.1-pro. Released 6 August 2026. Latest version.

Everything in 2.0, plus:

• Photo and video sharing modes: NORMAL and EAGER now differ on explicit content. Upgrading: on EAGER nothing changes. On NORMAL, if you rely on nude content being shared, switch to EAGER first.
• First reply follows the conversation: she answers in the tone the User set, instead of opening with small talk. Upgrading: a flirty or sexual opener now gets answered in kind, as far as sexualDrive allows.

Switching version

Set replyParameters.chatModel to chat-2.1-smart or chat-2.1-pro. Nothing to migrate: the next request runs on the version you name. Smart or Pro is a separate choice, covered in Choose Your Model.

Version 2.0 has no .0 in its model id. The legacy dating-smart-1 and dating-pro-1 models are still served, without Vision Link or Smart Share. Every release is listed in the changelog.
