What happened this week in AI by Louie
This week we saw several new competitors in the world of LLMs, in both open-source and closed models. Despite its impressive capabilities, the first version of the LLaMA model had licensing limitations that restricted its use exclusively to academic scenarios, which was considered one of its drawbacks. Now, Meta has recently unveiled LLaMA 2, which comes with a commercial use license. The latest model has been trained on an additional 40% of data, amounting to 2 trillion tokens, and possesses twice the context length, reaching an impressive 4096 tokens. LLaMA 2 surpasses models such as MPT and Falcon when evaluated against the chosen benchmarks. The model will be available for the public through Amazon AWS, Microsoft Azure, and Huggingface in three different sizes. (7B, 13B, 70B)
In other news, after conducting a lengthy private test of their initial Claude model, Anthropic has now made the Claude 2 language model publicly available. It is a ChatGPT competitor which is accessible through the claude.ai address. Their model reportedly scored 76.5% on the Bar exam (a 3.5% improvement) and placed in the 90th percentile on the GRE. Furthermore, the model is now accessible through API access, enabling businesses and individuals to leverage it as a foundation for their own applications and projects. The evaluation of the model reveals that it excels in providing harmless responses, exhibiting a twofold improvement. This achievement aligns with the vision of Anthropic's founders upon their departure from OpenAI.As part of their ongoing exploration, they are currently investigating the feasibility of training-aligned models. To this end, they are conducting an experiment involving the training of a "Decepticon" variant of Claude. The objective is to identify the specific source of deception within models.
At the beginning of the week, Elon Musk announced the establishment of xAI, a new company that directly competes with OpenAI. The primary objective of xAI is to develop Artificial General Intelligence (AGI) to gain a deeper understanding of the true nature of the universe. The company has assembled an impressive team of talented individuals from renowned organizations such as DeepMind, OpenAI, Google, and Microsoft. At present, there is a lack of specific information about the company. Nevertheless, we think its strong team, financial backing, and ambition mean it is likely to become an important contributor to the field.

Anthropic has released Claude 2, an advanced AI model that outperforms Claude 1.3 in various evaluations, achieving impressive scores on Codex HumanEval and GSM8k. Claude 2 excels in coding, math, and even scored higher on the Bar exam. Additionally, it offers improved effectiveness in generating harmless responses and can handle inputs up to 100K tokens.
Elon Musk's new AI startup, xAI, is recruiting top engineers from tech giants like Google and Microsoft to develop a "maximally curious" AI. Although separate from X Corp, xAI will closely collaborate with companies like Twitter and Tesla, aiming to bring about breakthroughs and innovation in the field of AI through synergistic efforts.
Bard, a language model, has expanded its availability worldwide and now supports multiple languages. New features include the ability to listen to Bard's responses, customize the tone and style of its output, pin and rename past conversations, export Python code to Replit and Google Colab, and utilize images in prompts with the help of Google Lens integration.
Stanford researchers found that over 50% of essays written by non-native speakers were flagged as AI-generated, emphasizing the need to address the discrimination faced by non-native writers using AI detectors. This has implications for college and job applications as well as search engine algorithms, potentially harming academic careers and psychological well-being.
Shutterstock announced its plans to expand its existing deal with OpenAI to provide the startup with training data for its AI models. In turn, Shutterstock will gain "priority access" to OpenAI's latest tech and new editing capabilities. Additionally, Shutterstock is working towards becoming a leader in generative AI by collaborating with top AI companies and compensating artists for their contributions to training the AI.

This guide explains how to use QLoRA on Amazon SageMaker for fine-tuning large language models. It highlights the usage of tools like Hugging Face Transformers, Accelerate, and the PEFT library for adapting pre-trained language models to different applications without fine-tuning all parameters. It also emphasizes the advantages of QLoRA.
NLP plays a crucial role in content marketing as it automates content generation, optimizes it for search engines, gauges sentiment, segments audiences, powers chatbots, and virtual assistants, conducts social listening, and aids in content curation. This article provides an overview of how to effectively utilize NLP to scale content marketing.
This article shares GitHub's efforts with LLMs to assist developers in harnessing the technology to its fullest potential. It provides a high-level overview of how LLMs operate and offers guidance on constructing LLM applications. It utilizes GitHub Copilot code completions as a prime illustration of an LLM-based application.

Papers & Repositories
This paper proposes Instruct Mining, a linear rule for evaluating the quality of instruction-following data. With a 42.5% improvement over models that use unfiltered data, this approach emphasizes the importance of data quality in fine-tuning LLMs for effective interpretation of instructions. The selection process employs natural language indicators such as naturalness, coherence, and understandability.
The paper introduces Emu, a Transformer-based multimodal foundation model capable of seamlessly generating images and texts in a multimodal context. It can handle diverse types of data input, including images, text, and videos, and surpasses other large multimodal models in tasks such as image captioning, visual question answering, and text-to-image generation.
This paper introduces the Instruction Following Score (IFS), a metric that detects the ability of language models to follow instructions. It aids in distinguishing between base and instruct models, thereby preventing unnecessary fine-tuning that could alter a model's semantics. Furthermore, researchers have observed that significant semantic shifts occur when the IFS plateaus, underscoring the relationship between instruction following and model semantics.
This work establishes provably faster convergence rates for gradient descent through the utilization of a computer-assisted analysis technique. The convergence rate of optimization methods represents the mathematical limit of how quickly a model can identify the optimal solution under the guidance of that particular optimization method. The cyclical learning rates can be enhanced by occasionally taking substantial steps.
GPT4RoI is an innovative model that enhances vision-language tasks by incorporating regions of interest. This incorporation enables precise alignment between visual features and language embeddings, thereby empowering users to interact with the model through language and spatial instructions.
