Using these prompts with Claude, ChatGPT, Gemini, and Llama
These prompts work well across all modern chat models — Claude, ChatGPT, Gemini, Llama, Mistral, and DeepSeek. For Claude 4 you can wrap the persona in <role> tags to encourage stronger in-character responses. For Gemini 2.5 and Llama 4, paste the prompt as the first user message and it will be treated as the active persona for the rest of the conversation.
If you need to count tokens, measure cost or compress a long persona before pasting it into an API call, pair this tool with our Token Counter, Prompt Compressor, or Persona Generator to build a custom persona from scratch.
