Description | Usecase

• The result of this merge is in my opinion a more vibrant and less generic sonnet inspired prose, it's able to be gentle and harsh where asked.
• The v2 uses the non-kto magnum which tends to have less "claudeism" (making the story feel rather repetitive)
• Note on Non-Kto: There is a very big gap between people preferring and disliking the KTO. To make things easier, you can still use Luni/StarDust-12b-v1 which has the KTO version.
• In early testing users have reported a much better experience in longer roleplays and a abillity to add a creative touch to the stable experience.

Just like with v1:

• This model is intended to be used as a Role-playing model.
• Its direct conversational output is... I can't even say it's luck, it's just not made for it.
• Extension to Conversational output: The Model is designed for roleplay, direct instructing or general purpose is NOT recommended.
• It can be used with simple setup to be used as an "Agent" by forcing it into an "impersonation" of a character which works very well but sometimes narratives sneak in.

Initial Feedback

• Initial feedback has proven the model to be a solid "go-to" choice for creative storywriting
• The prose has been certified as "amazing" with many making it their default model.

Prompting

ChatML has proven to be the BEST choice.

Both Mistral and ChatML should work though I had better results with ChatML: ChatML Example:

"""<|im_start|>user
Hi there!<|im_end|>
<|im_start|>assistant
Nice to meet you!<|im_end|>
<|im_start|>user
Can I ask a question?<|im_end|>
<|im_start|>assistant
"""
