Very cool app, if anyone wants to try the FOSS alternative to this check out Ragdoll Studio - https://github.com/bennyschmidt/ragdoll-studio
Create anyone you want based on a list of documents (URLs), chat with them, have them create images in their style, tell stories, etc.
(runs open models with Ollama, Stable Diffusion, etc. not OpenAI)
I would be curious what Sam Altmans people make, you can share characters here: https://ragdoll-studio.vercel.app
