 With SlideDeck AI, co-create slide decks on any topic with Generative Artificial Intelligence.
 Describe your topic and let SlideDeck AI generate a PowerPoint slide deck for you—it's as simple as that!
 
+SlideDeck AI is powered by [Mistral 7B Instruct](https://huggingface.co/mistralai/Mistral-7B-Instruct-v0.1).
+Originally, it was built using the Llama 2 API provided by Clarifai.
 
 # Process
 
 SlideDeck AI works in the following way:
 
-1. Given a topic description, it uses Llama 2 to generate the outline/contents of the slides. 
+1. Given a topic description, it uses Mistral 7B Instruct to generate the outline/contents of the slides. 
 The output is generated as structured JSON data based on a pre-defined schema.
 2. Subsequently, it uses the `python-pptx` library to generate the slides, 
 based on the JSON data from the previous step. 
 Here, a user can choose from a set of three pre-defined presentation templates.
 3. In addition, it uses Metaphor to fetch Web pages related to the topic.
-4. Finally, it uses Stable Diffusion 2 to generate an image, based on the title and each slide heading.

 # Local Development
 
-SlideDeck AI uses the Clarifai API of LangChain to interact with Llama 2. 
-It also sends a Web request to Clarifai for the final step.
-To run this project by yourself, you need to provide the `CLARIFAI_PAT` and `METAPHOR_API_KEY` API keys,
-for example, in a `.env` file.
