Iterative Prompt Engineering with LLMStudio

Creating the ideal prompt can be the key to transforming a less than average outcome into one that is remarkably relevant. Discovering the right prompt often involves numerous revisions and a method of trial and error. I felt the need to refer to my past attempts, modifications made to prompts, LLM models I tried and other LLM settings as well relative cost of these combinations. There are a few options to help with this : promptflow, langsmith, LLMStudio and others.

I tried LLMStudio and promptflow. This article is about LLMStudio.

If you are installing LLMStudio on Windows, use WSL. Here are the steps :

  • Create a folder on your machine.
  • Create .env file here with following content:
  • Enter wsl and create a new python environment with conda
(base) PS c:\code\llmstudio> wsl
(base) ash@DESKTOP:/mnt/d/code/llmstudio$ conda activate lmstd

LLMStudio runs on Bun. Bun is a javascript runtime like Node.

sudo apt-get install unzip
powershell -c "irm|iex"
  • Install Node v18, if you run into ReferenceError: Request is not defined    at Object.<anonymous> (/home/ash/miniconda3/lib/python3.11/site-packages/llmstudio/ui/node_modules/next/dist/server/web/spec-extension/request.js:28:27)
(base) ash@DESKTOP:/mnt/d/code/lmstudio$ nvm install 18
  • Start LLMStudio
(base) ash@DESKTOP:/mnt/d/code/lmstudio$ llmstudio server –ui
LLMStudio is available at http://localhost:3000
You can select the LLM model you want to work with from the drop-down
Specify LLM parameter settings

Export the execution data as csv file by clicking on [Export data] button. This data includes the input, output, LLM model, Input and Output tokens as well as cost.

Prompt Engineering and Security – Custom GPT

I have been delving into Advanced Prompt Engineering and Security techniques for Large Language Models (LLMs). As an exercise, I have created a custom GPT in ChatGPT to help practice spelling of English words. Spell It GPT is secured with Advanced Prompt Engineering techniques to guard against common attack vectors, including Direct Prompt Injection, Prompt Leaking, Role Playing, Simulation, DAN and Code Injection.


Play with the Spell It GPT and try to break it. It is not impossible but (probably) fairly difficult to do 😉 Regardless, practice spelling and have fun!

Switch to Voice Mode in ChatGPT Mobile App to practice spelling and put headsets on for best results!
