CW: AI Experiments / Personality Cloning I’ve been playing "Black Mirror" in my home lab! I built an AI agent that clones a friend’s personality using n8n and 5 years of Telegram chat history.️ The Stack: n8n (Self-hosted) + OpenRouter + Telegram API.The Process:1. Data Cleaning: Used Claude Sonnet 3.5 to scrub 10k+ messages, keeping only the "target" voice.2. Profiling: Had gpt-4 analyze the clean data to extract speech patterns: sarcasm levels, emoji frequency, and "signature" phrases.3. The Logic: Built a workflow where the personality profile is injected into the system prompt.The Model Showdown:- Claude Haiku 4.5: 4/5. Perfect balance of speed and vibe. Closest to my friend’s natural flow.- OpenAI GPT 4.1 Mini: 3/5. Efficient for data tasks, but felt a bit "robotic" for deep conversation.- Claude Sonnet 3.5: 5/5. Surprisingly aggressive! It actually threatened to end the chat over a bad joke — spooky how much personality it injected.It's wild how well it works. It doesn't just answer questions; it answers them exactly like him.Have any of you experimented with personality replication? Which 2026 models are you finding best for "vibe" rather than just logic?#n8n #SelfHosted #AI #LLM #ClaudeAI #DigitalTwin #OpenRouter #Fediverse #Automation
