Summary Agents are a popular application of Large Language Models (LLMs), providing a framework that allows these models to make decisions, utilize tools, and complete tasks. One such implementation, the Transformers Agents, has been enhanced with LlamaIndex to create a Text2Image Prompt Assistant tool, which refines prompts for generating visually appealing images. By indexing 10,000 prompts from DiffusionDB, the tool can rewrite prompts to improve image quality, and the process of creating and sharing custom tools is facilitated through Hugging Face Spaces. Challenges in tool implementation, such as the selection of a single tool for each prompt and ensuring all necessary components are downloaded, have been addressed, allowing for a straightforward execution of the tool. Testing with an OpenAIAgent using the text-davinci-003 model demonstrated that the new prompt assistant tool can generate more stylized and refined images.
