Roleplay fit
Claude models are widely regarded for nuanced, in-character writing and for following detailed system prompts and character cards closely.
Context behavior
With a 1,000,000-token context window, it can hold a long-running roleplay or a full lorebook in memory without losing earlier plot details, so it suits multi-session campaigns and character cards with heavy backstory.
Cost for regular use
It is priced for quality-sensitive scenes, where writing quality and instruction-following matter more than minimizing per-message cost.
