Mistral Roleplay Locks Without Meta-Commentary

To prevent Mistral from generating multi-turn back-and-forth scripts or adding meta-disclaimers during character roleplay, Mistral's cookbook recommends pairing a single-reply system instruction with a "CharacterName: " prefix.

instruction = "Let's roleplay. Always give a single reply. Roleplay only, using dialogue only. Do not send any comments, notes, or disclaimers." prefix = "Shakespeare: " # Pass instruction in system role and prefix with "prefix": True in assistant role.
