How Do AI Girlfriends Work? Large Language Models & Memory Explained
A deep dive into natural language processing, vector memory stores, and generative speech systems powering companions.
The Architecture Behind AI Companions
Behind the interface of every companion app is a complex pipeline combining prompt engineering, memory embeddings, and speech synthesis.
1. The Language Model
The core intelligence originates from fine-tuned neural models trained on dialogue datasets to produce supportive, conversational prose.
2. Long-Term Memory (RAG)
Retrieval-Augmented Generation (RAG) allows the companion to store key facts about you (hobbies, names, preferences) and pull them dynamically into new chats.
