This week, a largely unknown company, Groq, demonstrated unprecedented speed running open-source LLMs such as Llama-2 (70 billion parameters) at more than 100 tokens per second, and Mixtral at nearly 500 tokens per second per user on a Groq’s Language Processing Unit (LPU). |
For the comparison: |
“According to Groq, in similar tests, ChatGPT loads at 40-50 tokens per second, and Bard at 70 tokens per second on typical GPU-based computing systems. Context for 100 tokens per second per user – A user could generate a 4,000-word essay in just over a minute.”
|
So: What is LPU, how does it work, and where is Groq (such an unfortunate name, given Musk's Grok is all over the media) coming from? |
Remember that game of Go in 2016 when AlphaGo played against the world champion Lee Sedol and won? Well, about a month before the competition, there was a test game which AlphaGo lost. The researchers from DeepMind ported AlphaGo to Tensor Processing Unit (TPU) and then the computer program was able to win by a wide margin. |
The realization that computational power was a bottleneck for AI's potential led to the inception of Groq and the creation of the LPU. This realization came to Jonathan Ross who initially began what became TPU project in Google. He started Groq in 2016. |
The LPU is a special kind of computer brain designed to handle language tasks very quickly. Unlike other computer chips that do many things at once (parallel processing), the LPU works on tasks one after the other (sequential processing), which is perfect for understanding and generating language. Imagine it like a relay race where each runner (chip) passes the baton (data) to the next, making everything run super fast. The LPU is designed to overcome the two LLM bottlenecks: compute density and memory bandwidth. |
Groq took a novel approach right from the start, focusing on software and compiler development before even thinking about the hardware. They made sure the software could guide how the chips talk to each other, ensuring they work together seamlessly like a team in a factory. This makes the LPU really good at processing language efficiently and at high speed, ideal for AI tasks that involve understanding or creating text. |
This led to a highly optimized system that not only runs circles around traditional setups in terms of speed but does so with greater cost efficiency and lower energy consumption. This is big news for industries like finance, government, and tech, where quick and accurate data processing is key. |
Now, don't go tossing out your GPUs just yet! While the LPU is a beast when it comes to inference, making light work of applying trained models to new data, GPUs still reign supreme in the training arena. The LPU and GPU might become the dynamic duo of AI hardware, each excelling in their respective roles. |
As Elvis Saravia put it: “With breakthroughs in inference and long context understanding, we are officially entering a new era in LLMs.” |
To better understand architecture, Groq offers two papers: from 2020 (Think Fast: A Tensor Streaming Processor (TSP) for Accelerating Deep Learning Workloads) and 2022 (A So ware-defined Tensor Streaming Multiprocessor for Large-scale Machine Learning). The term “LPU” must be a recent addition to Groq’s narrative, since it’s never mentioned in the papers. |

Compute is also a part of this paper: Computing Power and the Governance of Artificial Intelligence that discusses managing AI development through compute control, focusing on its potential for regulation, benefits, and risks, and suggests balanced governance approaches. Meanwhile, The U.S. awards GlobalFoundries, the world's third-largest contract chipmaker, $1.5 billion to boost semiconductor production, enhancing domestic supply chains, with expansions in New York and Vermont. The paper published by Berkeley Artificial Intelligence Research (BAIR) argues that “compound AI systems will likely be the best way to maximize AI results in the future, and might be one of the most impactful trends in AI in 2024.”
