IT cos bet big on SLMs for GenAI push

I know that trolls are going to go ballistic at this, that’s why I am trying stridently to clarify things. Some critics get themselves into a tizzy and believe that you either must favor LLMs or you must favor SLMs. You either love the largeness of LLMs and detest the smallness of SLMs, or you relish the compactness of SLMs and outright hate the oversized nature of LLMs. They seek to trap you into a mindset that somehow you must choose between the two. Yes, it would indeed be handy and alluring to have generative AI or LLM that runs on your own smart devices.

Voila, we have amazing computational fluency that appears to write as humans do in terms of being able to carry on conversations, write nifty stories, and otherwise make use of everyday language. Putting a SLM like Phi into common workflows, such as to quickly deliver readable and comprehensible summaries of key data, could prove quite useful. The result would be an intriguing ChatGPT App alternative to aging UI paradigms, especially when working with unstructured data. A quantized build of Phi 2 weighs in at under 1.9GB, small enough to be delivered as part of a web application. (You’ll find a Rust/WebAssembly demo application in the Hugging Face repo.) It’s slow to make an initial response while loading, but once the SLM is cached, it’s reasonably responsive.

Take out what might be data fluff now that we are being mindful about storage space and processing cycles, maybe change numeric formats to simpler ones, and come up with all kinds of clever trickery that might be applied. It is considered a model of natural language such as English and turns out is pretty large in size since that seemed initially to be the only way to get the pattern-matching to be any good. The largeness consists of having a large internal data structure that encompasses the modeled patterns, typically using what is called an artificial neural network or ANN, see my in-depth explanation at the link here. The need to properly establish this large data structure involved doing large scans of written content since just scanning slimly couldn’t move the needle on having viable pattern matching. With this set of optimizations, on iPhone 15 Pro we are able to reach time-to-first-token latency of about 0.6 millisecond per prompt token, and a generation rate of 30 tokens per second. Notably, this performance is attained before employing token speculation techniques, from which we see further enhancement on the token generation rate.

ACE NIM microservices allow developers to deploy state-of-the-art generative AI models through the cloud or on RTX AI PCs and workstations to bring AI to their games and applications. With ACE NIM microservices, non-playable characters (NPCs) can dynamically interact and converse with players in the game in real time. Releasing them under a permissive license such as Apache 2.0 would be like throwing away money. A company like Meta can afford those kinds of expenses, knowing that they will recoup the costs down the road as they integrate the models into their products.

The largeness meant that generative AI would only reasonably run on powerful computer servers and thus you needed to access the AI via the Internet or cloud services. That’s how most people currently use the major generative AI apps such as OpenAI’s ChatGPT, GPT-4o, o1, and other akin AI including Anthropic Claude, Google Gemini, Meta Llama, and others. We evaluate our models’ writing ability on our internal summarization and composition benchmarks, ChatGPT consisting of a variety of writing instructions. These results do not refer to our feature-specific adapter for summarization (seen in Figure 3), nor do we have an adapter focused on composition. Some projects have even managed to run LLaMA (or rather a version of it) on budget Android smartphones, further proving that we are on the right path to democratizing access to performative LMs using low computing resources (LLaMA.c [7]).

An Emphasis on Quality and Efficiency

SLM development commonly integrates techniques such as transfer learning from larger models and may incorporate advancements such as retrieval-augmented generation to optimize performance and expand the knowledge base. Our models have been created with the purpose of helping users do everyday activities across their Apple products, and developed responsibly at every stage and guided by Apple’s core values. We look forward to sharing more information soon on our broader family of generative models, including language, diffusion, and coding models. We compare our models with both open-source models (Phi-3, Gemma, Mistral, DBRX, Llama) and commercial models of comparable size (GPT-3.5, GPT-4)1. We find that our models are preferred by human graders over most comparable competitor models. On this benchmark, our on-device model, with ~3B parameters, outperforms larger models including Phi-3-mini, Mistral-7B, Gemma-7B, and Llama-3-8B.

• Microsoft’s Phi models were trained on fine-tuned “textbook-quality” data, says Mueller, which have a more consistent style that’s easier to learn from than the highly diverse text from across the Internet that LLMs typically rely on.
• To tackle potential inconsistencies between the SLM’s decisions and the LLM’s explanations, the framework incorporates mechanisms to enhance alignment.
• Community created roadmaps, articles, resources and journeys for developers to help you choose your path and grow in your career.
• In this article, I share some of the most promising examples of small language models on the market.
• However, the high expenses of training and maintaining big models, as well as the difficulties in customizing them for particular purposes, come as a challenge for them.

SLMs can’t match the breadth of tasks performed by Cohere; Anthropic’s Claude; and OpenAI’s GPT-4 on AWS, Google Cloud and Azure. However, SLMs trained on data for specific tasks, such as content generation from a specified knowledge base, show potential as a significantly less expensive alternative. The expense of using large language models on cloud providers is driving interest in models a fraction of the size to utilize generative AI in business. Small language models also fit into the edge computing trend, which is focusing on bringing AI capabilities closer to users.

Small is big: Meta bets on AI models for mobile devices

The difference here from classical power laws is that the open-source movement and third-party models will pull that torso shown in red up and to the right. Moreover, we see LLMs and SLMs evolving to become agentic, hence SAM – small action models. In our view, it’s the collection of these “S-models,” combined with an emerging data harmonization layer, that will enable systems of agents to work in concert and create high-impact business outcomes. These multi-agent systems will completely reshape the software industry generally and, more specifically, unleash a new productivity paradigm for organizations globally.

Mixtral 8x7B, which is in beta, has nearly 47 billion parameters but processes input and generates output at the speed and cost of a 13-billion-parameter model, according to Mistral. The French startup raised $415 million in funding this month, valuing the company at $2 billion. Many organizations are worried about data leaks when fine-tuning a cloud-based LLM with sensitive information. Providers of open source SLMs tout access to the models’ inner workings as a crucial enterprise feature.

While LLMs are a new technology, they have already become a major force in the enterprise sector. They excel in processing, summarizing and analyzing large volumes of data and offer valuable insights for decision-making. Then, there are the advanced capabilities for creating compelling content and translating foreign languages. He also emphasized the importance of small language models (SLMs) in Microsoft’s growth strategy. We believe that this shift mirrors past industry trends where open source and open standards became the norm.

• Google’s Nano model can run on-device, allowing it to work even when you don’t have an active internet connection.
• On 10 June, at Apple’s Worldwide Developers Conference, the company announced its “Apple Intelligence” models, which have around 3 billion parameters.
• It can reply to an uncapped range of queries because it taps into one billion or more parameters of data.
• We’ll also revisit our premise that the long tail of SLMs will emerge with a new, high-value component in the form of multiple agents that work together guided by business objectives and key metrics.

Once a base model had been generated, the team fine-tuned it with more detailed data, for example producing different tunings for different tasks. In SLMs, Microsoft is competing with other companies such as Stability AI, which recently released Stable LM 2 1.6B, which is smaller than Phi-2 but has high performance on key LLM benchmarks. And other research labs are close behind, finding ways to squeeze more out of small language models. There are now several open LLMs that compete with GPT-3.5 at a fraction of the size and costs.

As part of responsible development, we identified and evaluated specific risks inherent to summarization. For example, summaries occasionally remove important nuance or other details in ways that are undesirable. You can foun additiona information about ai customer service and artificial intelligence and NLP. However, we found that the summarization adapter did not amplify sensitive content in over 99% of targeted adversarial examples.

They are operating on substantially lower costs, proving their effectiveness. In situations where computational resources are limited and offer opportunities for deployment in different environments, this efficiency is particularly important. A new dimension to this narrative has recently emerged with the revelation of GPT 4.

3 min read – Solutions must offer insights that enable businesses to anticipate market shifts, mitigate risks and drive growth. These results highlight the Categorized approach’s ability to enhance consistency between detection and explanation in the hallucination detection framework, while also providing valuable feedback for system improvement. To tackle potential inconsistencies between the SLM’s decisions and the LLM’s explanations, the framework incorporates mechanisms to enhance alignment. This includes careful prompt engineering for the LLM and potential feedback loops where the LLM’s explanations can be used to refine the SLM’s detection criteria over time.

One example is GPT-4, which has various models, including GPT-4, GPT-4o (Omni), and GPT-4o mini. SLMs focus on key functionalities, and their small footprint means they can be deployed on different devices, including those that don’t have high-end slm vs llm hardware like mobile devices. For example, Google’s Nano is an on-device SLM built from the ground up that runs on mobile devices. Because of its small size, Nano can run locally with or without network connectivity, according to the company.

Similarly, in the legal industry, a firm might use an SLM trained in legal documents, case law, and regulatory texts to provide precise legal research and contract analysis, improving the efficiency and accuracy of legal advice. In the financial sector, a bank might implement an SLM trained on market data, financial reports, and economic indicators to generate targeted investment insights and risk assessments, enhancing decision-making and strategy development. Other business and operational areas where domain-specific SLMs could deliver more value at a lower cost are shown in Figure 1. In the ever-evolving domain of Artificial Intelligence (AI), where models like GPT-3 have been dominant for a long time, a silent but groundbreaking shift is taking place. Small Language Models (SLM) are emerging and challenging the prevailing narrative of their larger counterparts. Despite their excellent language abilities these models are expensive due to high energy consumption, considerable memory requirements as well as heavy computational costs.

This is particularly problematic for businesses that require precision and relevance in their AI applications[1]. Whether it is because of cost, data privacy or data sovereignty, enterprises might want to run these SLMs in their data centers. Gen AI at the edge performs the computation and inferencing as close to the data as possible, making it faster and more secure than through a cloud provider.

General business use cases for small language models

In comparison, SLMs use less amount of data, which are specific to the problem that the application is trying to solve. It is relatively cost effective than LLMs due to less use of computing power and cloud storage among others. Agentic workflows, which involve autonomous agents performing complex tasks through a series of interdependent steps, rely on more than one language model to achieve optimal results.

By training SLMs on lifestyle habits and genetic data, we can enhance preventive care, promote wellness, and ultimately improve quality of life. Effective communication not only involves speaking the patient’s language but also adjusting to their level of understanding. These AI models can translate complex medical jargon into easily understandable information. In the near future, we could expect LLMs to be culturally fluent, therefore adjusting their communication with patients according to their social and cultural context. Furthermore, SLM integration can streamline real-time insurance eligibility processes thanks to NLP’s ability to detect fraud when used in processing claims.

Detecting and mitigating these hallucinations is an ongoing challenge in the development of reliable and trustworthy language models. Reading comprehension and automated reasoning are standard tasks a language model is typically tested on. In our case, it could be exemplified as predicting words that could only be expected if the model could understand the relation between this word and the context that came before it (sometimes far from this word’s position).

Another tricky situation is when information needs to be inferred from context. For example, a medical assistant AI might infer the presence of a condition based on its symptoms without the medical condition being expressly stated. Identifying where those symptoms were mentioned would be a form of “weak grounding”. The justification for a response must exist in the context but the exact output can only be synthesised from the supplied information. A further grounding step could be to force the model to lookup the medical condition and justify that those symptoms are relevant.
