As indicated in our whitepaper, The Future of AI is Hybrid (part 1): Unlocking the generative AI future with on-device and hybrid AI, a main motivation for on-device and hybrid artificial intelligence (AI) is cost. That cost is driven by the increasing size of AI models, the cost of running these models on cloud resources, and the increasing use of AI across devices and applications. Let’s put that into perspective.
Foundation models, such as general-purpose large language models (LLMs) like GPT-4 and PaLM 2, have achieved unprecedented levels of language understanding, generation capabilities, and world knowledge. Most of these models are quite large and are growing rapidly. GPT-1 was first launched by OpenAI in 2018 with the second, third and fourth version in 2019, 2020 and 2023 respectively.
Although the size of state-of-the-art models continue to grow rapidly, another trend is toward much smaller models that still provide high-quality outputs. For example, Llama 2 with 7 or 13 billion parameters performs very well against much bigger models in generative AI benchmarks.2 Running these smaller models in the cloud will help reduce the cloud resources required.
The cost of cloud computing to ISPs
The current cloud-based computing architecture for LLM inferencing leads to higher operating costs for internet search companies (ISPs), big and small. Consider a future with internet search augmented by generative AI LLMs, like GPT-3 running with 175 billion parameters. Generative AI searches can provide a much better user experience and results, but the cost per query is estimated to increase by 10 times compared to traditional search methods, if not more according to a report by Reuters.3
That cost translates to expensive graphics-processing-unit and tensor-processing-unit-accelerated servers, the infrastructure to support these high-performance servers, and the energy costs of running these servers. According to TIRIAS Research, AI infrastructure costs could exceed $76 billion by 2028.5 There is currently no effective business model to pass this cost on to consumers. So, new business models are required, or the costs need to be reduced significantly.
The cost of increased use
Use of these models is also increasing exponentially. Generative AI models, such as GPT and Stable Diffusion, can create new and original content like text, images, video, audio, or other data from simple prompts today. Future generative AI models will be able to create complete movies, gaming environments, and even metaverses.
Architects and artists can explore new ideas, while engineers can create code more efficiently. Virtually any field that works with words, images, video, and automation can benefit.
ChatGPT has captured our imagination and engaged everyone’s curiosity to become the fastest growing app in history. ChatGPT reached more than 100 million active users in January 2023 just two months after it launched and now boasts more than 1.5 billion monthly visits, making OpenAI one of the top-20 websites in the world according to Reuters.6
Innovation is becoming more and more difficult to keep up with due to generative AI developments. According to a major aggregator site, there are more than 5,000 generative AI apps and features available.7 AI is having a Big Bang moment, akin to the launch of television, the worldwide web, or the smartphone. And this is just the beginning.
The cost-efficient path to reaching AI’s full potential
The most efficient solution to reduce the tremendous costs of running generative AI in the cloud is to move models to edge devices. Transitioning models to the edge not only reduces the stress on the cloud infrastructure, but it also reduces execution latency while increasing data privacy and security.
AI models with more than 1 billion parameters are already running on phones with performance and accuracy levels similar to those of the cloud, and models with 10 billion parameters or more are slated to run on devices in the coming months. For example, at Mobile World Congress (MWC) 2023, Qualcomm Technologies demonstrated Stable Diffusion running completely on a smartphone powered by a Snapdragon 8 Gen 2 mobile platform.
Over time, advances in model optimization combined with increased on-device AI processing capabilities will allow many generative AI applications to run on the edge. In a hybrid AI solution, distributing AI processing between the cloud and devices will allow generative AI to scale and reach its full potential — on-device AI processing and cloud computing will complement each other.
The hybrid AI approach is applicable to virtually all generative AI applications and device segments — including phones, laptops, extended reality headsets, vehicles and the internet of things. The approach is crucial for generative AI to meet enterprise and consumer needs globally.
