In this post, we demonstrate how to create a RAG-based application using LlamaIndex and an LLM. The following diagram shows the step-by-step architecture of this solution outlined in the following sections. RAG combines information retrieval with natural language generation to...
For simplicity in the block diagram illustration of the “self_attn” box, we omit the “Grouped Query Attention” operation and only showcase the modules which have associated weights. MLP Layer SwiGLU is an activation defined as follows in themodeling_llama.pyfile in...
three methods by which a generative language model can compute sentence embeddings from input sentences. In contrast to traditional models like BERT [2], which utilize [CLS] tokens to obtain sentence embeddings, our model operates on a decoder-based Transformer architecture and consequently does not ...

Model Architecture:Llama 3.2-Vision is built on top of the Llama 3.1 text-only model, which is an auto-regressive language model that uses an optimized transformer architecture. The tuned versions use supervised fine-tuning (SFT) and reinforcement learning with human feedback (RLHF) to align wi...
In this post, we explore building a contextual chatbot for financial services organizations using a RAG architecture with the Llama 2 foundation model and theHugging Face GPTJ-6B-FP16embeddings model, both available in SageMak...
