Fine tuning a small model that sounds like me, mostly

I’ve been experimenting with how much of our personality is encoded in the data we generate every day. We all have a digital exhaust—years of emails, texts, and chat logs. I figured, if I could distill 10 years of my own communication into a small, specialized model, I could create a personal AI that sounds like me. The result is a 73 MB LoRA “voice cartridge” that makes stock Gemma 4 E4B text like me—blind-judged 31/40 times over its base model. ...

At work, I build AI agents(trigger warning this is about LLMs) that are designed to help teachers avoid as much day to day drudgery as possible. We provide a system that, counterintuitively, is geared towards reducing the amount of time a teacher needs to spend in the app spelunking around. Need the latest assessment grades for Mrs Doe’s 3rd period? Just ask the Ai, it’ll go off and grab that information for you while you pour another cup of coffee. We use top of the line models from Anthropic to be as accurate, un-biased, error free as possible to achieve this. These models require API keys and 5-figures in engineering time just to put the guardrails in place to allow a Teacher/Administrator to use them in relative safety. ...
