Prompt Engineering Guide for CharacterGPT V2

A Prompt Guide on How to Create AI-Generated Characters with CharacterGPT V2

1. Introduction

CharacterGPT V2 is a significantly advanced version of the first iteration of the multimodal generative AI system that enables text-to-character creation, CharacterGPT V1. CharacterGPT V2 enables users to generate fully interactive and intelligent AI characters with backstories and individual personalities using a single-line prompt in natural language. In short, it enables Text-to-Character Generation or TTC.

Comparison of AI Characters generated using CharacterGPT V1 and CharacterGPT V2 using the same prompts

All AI Characters generated using the CharacterGPT V2 AI system will be compatible with the AI Protocol. This means the characters are ownable and interoperable across any other application built on the AI Protocol.

2. Core Prompt

The core structure of the prompt for CharacterGPT V2 can be understood as:

<Person> as <descriptor> who <characteristic or setting>

A fairy princess wearing a pink dress who has beautiful wings who loves to talk about AI and Blockchain
