LlamaIndex's latest newsletter highlights the introduction of multimodal capabilities in LlamaCloud, enabling the creation of Retrieval-Augmented Generation (RAG) pipelines that handle both text and image data across various document types. The update includes the integration of OpenAI's latest o1 model with LlamaIndex frameworks in Python and Typescript, and the launch of a Code Generation Agent Template in partnership with Weights & Biases for the NeurIPS AI Hacker Cup. These advancements facilitate the development of applications like a web app styled as an iPhone scientific calculator using LlamaIndex.TS workflows. Additionally, the newsletter features tutorials on building and testing LlamaIndex RAG applications, as well as upcoming webinars and recruitment opportunities for roles such as Founding AI Engineer and Founding Full-Stack Product Engineer.
