<aside> 🎉 Hi! I’m interested in Generative AI (GenAI) with a special focus on Large Language Models (LLMs). I’ve built apps and websites based on LLMs, and I enjoy studying their behavior from a human psychology perspective (you can call it the “psychology of AI”). I also study eXplainable AI (XAI) and its economic implications for consumers and firms. Recently, I developed an XAI method to help interpret LLM outputs (see papers ↓). The methods I use include game theory, machine learning, and natural language modeling.

Programming and LLM Experience

In my free time, I read about programming languages (Haskell, Elixir), Vim, and AI. I get passionate about our relation to technology (esp. LLMs) and I also blog about my workflow customizations.

• Update: I have been developing a programming language (started out as a DSL, as they always do…) called Pel. Trust me bruh, this is related to LLMs and marketing! 😉

I’m one of the contributors to https://github.com/ggerganov/llama.cpp, the most popular open-source LLM engine in the world (+48k ⭐ on Github). It’s the software that powers several LLM apps such as https://github.com/oobabooga/text-generation-webui, https://github.com/jmorganca/ollama, and https://github.com/Mozilla-Ocho/llamafile.
