Recently, Cerebras systems released a series of open source GPT-based large language models (LLMs) for the research community. The Silicon Valley-based firm has trained all its models using 16 CS-2 systems in their Andromeda AI supercomputer with 111 million, 256 million, 590 million, 1.3 billion, 2.7 billion, 6.7 billion, and 13 billion parameters.
What’s interesting is, Cerebras boasts of being the first company to utilise AI systems that do not rely on GPUs to train LLMs with a capacity of up to 13 billion parameters. The company is also sharing the models, weights, and training recipe under the industry standard Apache 2.0 licence.
This is also the first time that the company is branching out into the generative AI space, wanting to claim the piece of the pie. More than anything, the chip startup is trying to follow the footsteps of NVIDIA, as it explores AI—an uncharted territory for the firm established in 2015.
But Cerebras has not only taken a page out of NVIDIA’s book, one can argue that it is refining it and its timing is mere coincidence.
Cerebras started making waves as they foresaw the generative AI boom with large language models such as Microsoft NLG, OpenAI’s GPT-4, NVIDIA’s Megatron, and BAAI’s Wu Dao 2.0 among others. In 2021, they unveiled the world’s first multi-million core AI cluster architecture—-which could handle neural networks with up to 120 trillion parameters.
Later, in November of 2022, Cerebras introduced one of the biggest AI supercomputers—Andromeda.
NVIDIA, really?
Let’s take a look back. NVIDIA started as a manufacturer of GPUs for gaming and professional graphics applications. However, over the years, they evolved and expanded their product offerings, particularly in the field of AI and machine learning.
One of the key factors that enabled NVIDIA’s shift from a chip manufacturer to a foundational model provider was the development of their CUDA platform—parallel computing platform and programming model that allows software developers to use NVIDIA GPUs for general-purpose computing tasks, such as scientific computing, machine learning, and AI. This enabled NVIDIA to tap into new markets beyond gaming and graphics and establish themselves as a key player in the AI and ML space.
NVIDIA also invested heavily in developing hardware for deep learning, such as their Tesla GPUs and the Tensor Cores—which enabled more efficient and faster processing of deep learning algorithms, thus making it easier and more accessible for researchers and developers to create AI and ML models.
As large language models such as ChatGPT and DALL-E 2 launched generative AI into public consciousness, the buzz around generative AI soared to unparalleled levels in 2023. As a result, chips that support AI at scale have become crucial now more than ever and NVIDIA took over 88% of the GPU market, research indicates.
Consequently, a lot of users consider NVIDIA as the primary beneficiary of the flourishing generative AI domain.
However, Cerebras is directly taking on NVIDIA:
“While many companies have promised alternatives to NVIDIA GPUs, none have demonstrated both the ability to train large-scale models and the willingness to open source the results with permissive licenses,” the release read.
While OpenAI apparently utilised 10,000 NVIDIA GPUs to train ChatGPT, Cerebras claims to have trained their models to the highest accuracy for a given compute budget.
“These models are trained to the highest accuracy for a given compute budget (i.e., training efficient using the Chinchilla recipe) so they have lower training time, lower training cost, and use less energy than any existing public models.”
Cerebras also maintains that they completed the training in record time, cutting down the training time from typically multiple months to just under a few weeks. The team credited the speed of the CS-2 systems that make up Andromeda and their unique weight streaming architecture to easily distribute tasks over a large amount of compute.
Founder and CEO of Cerebras, Andrew Feldman, also talked about the firms’ open source efforts and how it has been welcomed by the community at large. He further added, “There is a big movement to close what has been open sourced in AI. . . It’s not surprising as there’s now huge money in it”.
“The excitement in the community, the progress we’ve made, has been in large part because it’s been so open”, Feldman added.
