<ul data-eligibleForWebStory="true">The individual set up their own GPT-powered coding assistant locally.The assistant was made accessible via an OpenAI-compatible API.A CLI app using argparse was created for better interaction.Prompt design is highlighted as crucial when working with LLMs.Responses were received in under 2 seconds and were of high quality.The quality of responses was comparable to GPT-4 for technical tasks.Exploration of using neovim RPC to display responses in a floating window inside the editor was done.This allowed for offline and personalized coding assistance.Benchmarking model changes over time was made easier through this setup.The project enhanced the individual's understanding of large language models significantly.
