# ChatAnything: Facetime Chat with LLM-Enhanced Personas
### DEMO INSTRUCTION
##### 0. Register
Input a OpenAI API Key of your own. This would be used to chat with openai-chatgpt. Make sure to disable the key afterwards🥹.
##### 1. Generate The init face😀 along with first chat
Input a Concept in the "Talking object" text box, then click on Generate button. The init face generation and module selection will be performed and used for the rest of this chat. Wait for a while and the video would be produced and played. Write simple concept for generating. The concept will be place on each prompt template for deciding the main concepts.
##### 2. Keep on Chatting🤑
Go on speak with the character. The init face and module selection will not reperform itself, now you are only chatting with the LM, along with the rendering of sadtalker. Hopefully, the API will not impose an excessive charge for this.


### FEATURES
##### 1. Upload a image for control/inversion starting point. Try some none face images and see how it works!
##### 2. seeding is provided. However if not providing a input image, there would be a random chosen facial landmark image for generating, which might include some randomness.
##### 3. Try out the examples.
##### 4. Say something and recorded your voice for a real facetime chat. Whisper will handle your voice, see setting-Whisper STT options.
##### 5. Decide whether to use the crop face out option, this will crop out the face from the generated image and render. This is promising for better animation rendering, however sometimes the croped image loses some elementary features of you intended concept.
