Model Update | Rose Series Enters Public Beta
Proprietary membership models free during Beta, with multi-model updates

Hi Rochatters,

This update brings the debut of Rochat's proprietary Rose Series, along with simultaneous updates to both membership and SOTA models.

Rose Series | In-House Roleplay Flagship (Public Beta)

Rose-A and Rose-B are Rochat's latest proprietary models, purpose-built for long-session, high-immersion roleplay:

  • Long-term memory: Outstanding performance in long-context scenarios, keeping character settings and story threads more coherent
  • Faster response: Smoother, more natural interaction pacing
  • Dual versions: Rose-A and Rose-B offer subtly different styles — feel free to switch between them and share your feedback

The Rose Series is a membership-tier model, free for all users during the public Beta. We warmly invite you to try it out and help us refine it.
