Cerebras slay GPUs and break the record for largest AI models trained on a single machine

Cerebras, the corporate behind the world’s largest accelerator chip, a CS-2 Wafer Scale Motor, simply introduced a milestone: coaching the world’s largest AI (Pure Language Processing) (NLP) mannequin on a single gadget. Whereas that in and of itself may imply many issues (it would not be a lot of a record-breaking if the earlier largest mannequin was educated in a smartwatch, for instance), the AI ​​mannequin Cerebras educated has soared towards a staggering – and unprecedented – 20 billion Trainer. All with out having to scale your workload throughout a number of accelerators. That is sufficient to suit into the newer really feel of the web, the picture from the textual content generator, 12 billion DALL-E parameters from OpenAI (Opens in a brand new tab).

An important a part of reaching Cerebras is lowering infrastructure necessities and software program complexity. Positive sufficient, one CS-2 is sort of a supercomputer by itself. Chip Scale Engine -2 — which, because the title suggests, is etched right into a single, 7nm chip, normally sufficient for lots of of most important chips — options 2.6 trillion 7nm transistors, 850,000 cores, and 40GB of cache constructed right into a bundle that takes up about 15k Watts.

Preserving as much as 20 billion NLP mannequin variants in a single chip considerably reduces overhead in coaching prices throughout 1000’s of GPUs (and their related {hardware} and scaling necessities) whereas eliminating the technical difficulties of segmenting fashions throughout. That is “one of many extra painful elements of NLP workloads,” Cerebras says, “typically taking months to finish.”

It is a particular and distinctive concern not only for every neural community being processed, the specification for every GPU, and the community that ties all of it collectively – objects that have to be laid out beforehand earlier than the primary ever coaching begins. It can’t be transferred throughout methods.

Pure numbers could make Cerebras’ achievement look irritating – OpenAI’s GPT-3, a NLP paradigm that may write total articles Human readers can typically be deceived, Options an astounding 175 billion parameters. DeepMind’s Gopher, which launched late final yr, Bringing this quantity to 280 billion. The brains at Google Mind introduced the coaching of a Trillion modulus plus mannequin, switching transformer.
