This article introduces five most distinguished LLMs that have made a considerable impact as of June 2023 - Falcon, MPT, FastChat-T5, OpenLLaMA, and RedPajama-INCITE. Each of these models has demonstrated significant technical prowess in terms of architecture, computational efficiency, versatility of use cases, and marked improvements in performance. For conversational, summarization, and text-related tasks, FastChat-T5, with 3 billion parameters, is the most cost-effective. It runs on an Nvidia T4 GPU and can be finetuned for downstream tasks. For advanced applications like code generation, reading comprehension, and problem-solving, Falcon and MPT with 7 billion parameters are recommended. They are hosted on an Nvidia A10G GPU with 20GB RAM. If more power is required, Falcon-40B and MPT-30B can be used, with MPT-30B requiring an Nvidia A100 GPU with 80GB RAM. Note that Falcon-40B doesn't fit in a single A100 GPU.
Language Models (LMs) are designed to estimate the distribution of words (tokens) in a text. Their primary goal is to predict the next token in a given sequence of tokens. For example, given the phrase "Hinton is a great _", an LM might predict the next token probabilities "human" (0.95), "scientist" (0.03), or "brain" (0.01), among others.
Large Language Models (LLMs) are neural network-based language models with over 1 billion parameters. By learning from vast quantities of text data, these models can mimic human behavior and perform various downstream tasks such as Question Answering, Summarization, Translation, and more.
LLMs commonly utilize the transformer architecture (Vaswani et. al, 2017), which introduced the concept of self-attention, making it suitable for parallelizable compute resources like GPUs and TPUs. To achieve a robust understanding of language, these models require pretraining on a large corpus of data. Once pretrained, LLMs can be fine-tuned on smaller datasets for specific downstream tasks.
Trained using bidirectional context, these models aim to establish strong representations of language. Since the model has a bidirectional context, they are pre-trained using the Masked Language Modeling (MLM) task, in which a portion of input tokens are masked, and the model is tasked with predicting the masked tokens. Text representations can be finetuned and used for downstream tasks like Classification, Question Answering, Named Entity Recognition etc. Some well-known encoder models that utilize this approach include BERT, RoBERTa, ALBERT, and DeBERTa.
In these models, a prefix is given as input to the encoder, and the decoder predicts the output. The input utilizes bidirectional context. Studies have shown that corrupting spans of text and tasking the decoder with predicting the spans yields the best results (Rafael et al. 2019, and YiTay et al.2022). The T5 paper (Rafael et al. 2019) demonstrates models pretrained using span corruption and fine-tuned on various tasks, such as question answering, using 12 different fine-tuning tasks. The UL2 Paper (YiTay et al.2022) shows specific ways of denoising and choosing the span that unifies language learning.
These are the most common types of Language Models. They have a Causal LM objective to predict the full sequence length. These are commonly used for text-generation tasks. They can also be fine-tuned for downstream tasks by adding a classifier over the last token's hidden representation. OpenAI's GPT-1, GPT-2, and GPT-3 are examples of decoder models.
