MPT-7B: Revolutionizing Open-Source, Commercially Usable LLMs

Introduction:

Large Language Models (LLMs) have been transformative in various industries, but access to these models has been a challenge for many due to limitations in resources and availability. However, the landscape is evolving with the introduction of MPT-7B, the latest addition to the MosaicML Foundation Series. MPT-7B sets a new standard for open-source, commercially usable LLMs and opens up possibilities for businesses and the open-source community alike. In this article, we will explore the groundbreaking features of MPT-7B and its potential impact.

The Need for Open-Source LLMs:

The demand for open-source LLMs has spurred significant activity, with projects like LLaMA from Meta, Pythia from EleutherAI, StableLM from StabilityAI, and OpenLLaMA from Berkeley AI Research gaining attention. These initiatives have aimed to democratize access to LLMs, but limitations persist. MosaicML addresses these challenges by introducing the MPT series, specifically MPT-7B, which overcomes many of the limitations present in existing open-source models.

Key Features of MPT-7B: MPT-7B is a transformer model trained from scratch on an impressive 1 trillion tokens of text and code. It boasts open-source availability and commercial usability while matching the quality of the esteemed LLaMA-7B model. Here are some notable features of MPT-7B:

1.       Licensed for commercial use: Unlike LLaMA, MPT-7B is specifically designed to cater to commercial applications, providing businesses with greater flexibility and opportunities for innovation.

2.       Trained on a large amount of data: MPT-7B's training dataset consists of 1 trillion tokens, comparable to LLaMA while surpassing the token counts of other open-source models.

3.       Handling extremely long inputs: MPT-7B leverages ALiBi, enabling it to handle inputs up to 65k tokens and even extrapolate beyond that. This sets MPT-7B apart from other open-source models with much smaller context length limits.

4.       Optimized for efficiency: MPT-7B incorporates FlashAttention and FasterTransformer, resulting in fast training and inference times, making it an efficient choice for various applications.

Building on MPT-7B: In addition to the base MPT-7B model, MosaicML provides three finetuned variants: MPT-7B-Instruct, MPT-7B-Chat, and MPT-7B-StoryWriter-65k+. These variants showcase the versatility and potential of building upon the MPT-7B base model for specific use cases, such as instruction-following, chatbot-like dialogue generation, and writing stories with super long context lengths.

Driving Innovation with MPT-7B: MPT-7B's release goes beyond offering just a model checkpoint; it provides an entire framework for building powerful LLMs. The MosaicML LLM Foundry, along with the model checkpoints, open-sources the codebase for pretraining, finetuning, and evaluating MPT models. This empowers businesses and the open-source community to create their own custom MPT models efficiently, with a focus on efficiency, ease of use, and meticulous attention to detail.

The Impact of MPT-7B: The MosaicML NLP team trained MPT-7B in just 9.5 days, with zero human intervention, using the MosaicML platform. This achievement exemplifies the potential for rapid development and deployment of LLMs, enabling organizations to leverage the power of these models with minimal time and resource investments.

Conclusion: With MPT-7B, the MosaicML Foundation Series ushers in a new era of open-source, commercially usable LLMs. By addressing the limitations of existing models and providing extensive documentation and open-sourced code, MPT-7B empowers businesses and the open-source community to drive innovation and make transformative strides in natural language processing. Let's embrace this revolutionary tool and unlock the full potential of language models.

Koala: A Dialogue Model for Academic Research

  Koala: A Dialogue Model for Academic Research Introduction The accidental leak of the weights associated with Meta AI’s LLM LLaMA has sparked tremendous innovation in the open-source LLM space. Since the furious leak, we have seen models like Alpaca, Vicuna, ChatLlama, and several others expand on the foundations of LLaMA to build innovative conversational agents that match the capabilities of ChatGPT. One of the latest additions to the list is Koala (yes, I know, another animal-named model), a chatbot created by Berkeley AI Research (BAIR) that fine-tunes LLaMA on conversations gathered from the internet. The core goal of Koala is to highlight the balance between mega-large closed-source LLMs and smaller, open-source LLMs. BAIR’s thesis is that smaller models can achieve performance that matches mega models like ChatGPT with a fraction of the cost while also improving in areas such as fine-tuning, transparency, and many others. Koala Koala is a version of LLaMA fine-tu...

  What is FLAN-T5? Artificial Intelligence (AI) has been making strides in recent times, with advancements in Large Language Models (LLMs) and their applications taking much of the credit. One of the most prominent models in this domain is GPT-3, developed by OpenAI. However, it is not the only model making waves. FLAN-T5, developed by Google Research, has been getting a lot of eyes on it as a potential alternative to GPT-3. ·        FLAN stands for “Fine-tuned Language Net”         ·        T-5 stands for “Text-To-Text Transfer Transformer” Back in 2019, Google's first published a paper "Exploring the Limits of Transfer Learning with a Unified Text-to-Text Transformer", introducing a novel where they introduced the original T5 architecture. The pretrained encoder-decoder model worked well on multiple tasks, and particlarly well suited for translation and summarization tasks. In 2022 G...
