Understanding LLMs and Open-source LLMs
Large Language Models (LLMs) are advanced natural language processing models that can understand and generate human-like text. These models have become increasingly important in various applications such as language understanding, programming, and mathematics.
Open-source LLMs play a crucial role in the development and advancement of natural language processing technology. They provide the open community and enterprises with access to cutting-edge language models, enabling them to build and customize their models for specific applications and use cases.
What is Databricks DBRX?
Databricks DBRX is an open, general-purpose Large Language Model (LLM) developed by Databricks. It has set a new state-of-the-art for established open LLMs, surpassing GPT-3.5 and rivaling Gemini 1.0 Pro. DBRX excels in various benchmarks, including language understanding, programming, and mathematics. It is trained using next-token prediction with a fine-grained mixture-of-experts (MoE) architecture, resulting in significant improvements in training and inference performance.
The model is available for Databricks customers via APIs and can be pre-trained or fine-tuned. Its efficiency is highlighted by the training and inference performance, surpassing other established models while being approximately 40% of the size of similar models. DBRX is a pivotal component of Databricks’ next generation of GenAI products, designed to empower enterprises and the open community.
The MoE Architecture of Databricks DBRX
Databricks’ DBRX stands out as an open-source, general-purpose Large Language Model (LLM) with a unique architecture for efficiency. Here’s a breakdown of its key features:
- Fine-grained Mixture-of-Experts (MoE): This innovative architecture utilizes 132 billion total parameters, with only 36 billion active per input. This focus on active parameters significantly improves efficiency compared to other models.
- Expert Power: DBRX employs 16 experts and selects 4 for each task, offering a staggering 65 times more possible expert combinations, leading to superior model quality.
- Advanced Techniques: The model leverages cutting-edge techniques like rotary position encodings (RoPE), gated linear units (GLU), and grouped query attention (GQA), further boosting its performance.
- Efficiency Champion: DBRX boasts inference speeds up to twice as fast as LLaMA2-70B. Additionally, it boasts a compact size, being roughly 40% smaller than Grok-1 in both total and active parameter counts.
- Real-World Performance: When hosted on Mosaic AI Model Serving, DBRX delivers text generation speeds of up to 150 tokens per second per user.
- Training Efficiency Leader: The training process for DBRX demonstrates significant improvements in compute efficiency. It requires roughly half the FLOPs (Floating-point Operations) compared to training dense models for the same level of final quality.
Training DBRX
Training a powerful LLM like DBRX isn’t without its hurdles. Here’s a closer look at the training process:
- Challenges: Developing mixture-of-experts models like DBRX presented significant scientific and performance roadblocks. Databricks needed to overcome these challenges to create a robust pipeline capable of efficiently training DBRX-class models.
- Efficiency Breakthrough: The training process for DBRX has achieved remarkable improvements in compute efficiency. Take DBRX MoE-B, a smaller model in the DBRX family, which required 1.7 times fewer FLOPs (Floating-point Operations) to reach a score of 45.5% on the Databricks LLM Gauntlet compared to other models.
- Efficiency Leader: This achievement highlights the effectiveness of the DBRX training process. It positions DBRX as a leader among open-source models and even rivals GPT-3.5 Turbo on RAG tasks, all while boasting superior efficiency.
