SummaryIn this episode, Dalton Anderson discusses the research paper 'Herd of LLMs' released by Meta. He provides an overview of the models and their capabilities, the pre-training and post-training processes, and the emphasis on safety. The paper covers topics such as model architecture, tokenization, and data filtering. Dalton highlights the importance of open sourcing research and models, and the potential for businesses to utilize and build upon these models. In this conversation, Dalton Anderson discusses the architecture and training process of the LAMA 3.1 language model. He explains the pre-training and fine-tuning stages, as well as the challenges faced in mathematical reasoning and long context handling. He also highlights the importance of safety measures in open-source models. Overall, the conversation provides insights into the inner workings of LAMA 3.1 and its applications.KeywordsMeta, LLMs, research paper, models, capabilities, pre-training, post-training, safety, model architecture, tokenization, data filtering, open sourcing, LAMA 3.1, architecture, training process, pre-training, fine-tuning, mathematical reasoning, long context handling, safety measuresTakeawaysMeta's 'Herd of LLMs' research paper discusses the models and their capabilitiesThe pre-training and post-training processes are crucial for model developmentModel architecture, tokenization, and data filtering are important considerationsOpen sourcing research and models allows for collaboration and innovation LAMA 3.1 goes through a pre-training stage where it learns from a large corpus of text and a fine-tuning stage where it is trained on specific tasks.The training process involves creating checkpoints to save model parameters and comparing changes made at different checkpoints.The compute used for training LAMA 3.1 includes 16,000 H100 GPUs and Meta's Grand Tena and Tyons AI servers.LAMA 3.1 utilizes Meta's server racks, GPUs from Nvidia, and a job scheduler made by Meta.The file system used by LAMA 3.1 is the tectonic file distribution system, which has a throughput of 2-7 terabytes per second.Challenges in training LAMA 3.1 include lack of prompts for complex math problems, lack of ground truth for thought, and training inference disparity.Safety measures are crucial for open-source models like LAMA 3.1, and uplift testing and red teaming are conducted to identify vulnerabilities.Insecure code generation, prompt injection, and phishing attacks are some of the concerns addressed in the safety measures of LAMA 3.1.Sound Bites"What Meta is doing with open sourcing their research and their model is huge.""Meta's foundational model is second to third to first in most benchmarks.""The model architecture mirrors the Llama2 architecture, utilizing a dense transformer architecture.""They do this anewing, anewing, and then they would save the checkpoint and they would save it like, okay, so they did their training.""They were talking about the compute budgets. And so they were saying these things called flaps. And so it's 10 to the 18 and then 10 to the 20 times six and flop is a floating point operation per second, which comes down to six tillian, which is 21 zeros.""They have the server racks. They open sourced and designed basically themselves like a long time ago."Chapters00:00 Introduction and Overview02:54 Review of 'Herd of LLMs' and Model Capabilities05:52 Meta's Open-Sourcing Initiative09:06 Model Architecture and Tokenization16:07 Understanding Learning Rate Annealing22:49 Optimal Model Size and Compute Resources32:38 Annealing the Data for High-Quality Examples35:19 The Benefits of Open-Sourcing Research and Models44:08 Addressing Challenges in Data Pruning and Coding Capabilities50:19 Multilingual Training and Mathematical Reasoning in LAMA 3.101:01:37 Handling Long Contexts and Ensuring Safety in LAMA 3.1https://ai.meta.com/research/publications/the-llama-3-herd-of-models/
