I had previously used the stable-diffusion model and now with its new version out trying to see what has changed in Stable Diffusion XL. I deployed on AWS with SageMaker. My notebook is is available in github (see text_to_image_stability_xl). Multi-prompting looks be a new change but it does not work…

Sometimes I teach at a local community college. While I have not since ChatGPT became popular, I wonder how assessments need to be reimagined. I see articles on instructors disallowing use of ChatGPT and some instructors even withholding grades. In my opinion, those are not productive options. For a perspective…

Finally I got access to Azure OpenAI so recreating my previous example to work with Azure OpenAI. It is generally similar and the differences are highlighted in this Azure doc. There are some minor LangChain and LlamaIndex changes too. You need to complete the prerequisites steps documented…

In the last few weeks, I have created some simple applications for a custom data, chained chatbot using OpenAI and also deployed some local models for chat and image generation. Taking a step back, this week is my attempt to understand the bigger picture when it comes to the recent…

So far I tried running models in AWS SageMaker and used the OpenAI APIs. There are some local options too and with only a CPU. The response times are relatively high, and the quality of responses do not match OpenAI but none the less, this is an important step in…

My social feeds are full of generative AI so with fomo in mind here is an attempt to create my own chatbot, using OpenAI APIs, and augmented with custom data. There are way too many options, so this exercise has been about figuring out the tools to pick and stitching…

Yes this is not new anymore, but I’m finally getting around to doing this for myself! There are simple apps anyone can use, however in this article I explore using some models, deploying them myself and then generating images and learn about prompting. Hugging Face lists numerous text-to-image models so…

This story is part of a series. See this starting page for links to other lessons. In this lesson we will create a night light that turns on when its dark and turns off when there is light. Recall Lesson 4 where we used a LDR that made a light…

This story is part of a series. See this starting page for links to other lessons. In this lesson we will learn what is a NOT logic gate and build it with a transistor. In this circuit when you send electricity then the LED turns off and when you don’t…
