Cerebras-GPT vs LLaMA AI Mannequin Comparability
On March twenty eighth, Cerebras launched on HuggingFace a brand new Open
Supply mannequin skilled on The Pile dataset referred to as “Cerebras-GPT” with GPT-3-like
efficiency. ([Link to press release]

What makes Cerebras attention-grabbing?
Whereas Cerebras is not as able to a mannequin for performing duties when put next on to fashions like LLaMA,
ChatGPT, or GPT-4, it has one necessary high quality that units it aside: It has been launched below the Apache 2.0 licence,
a completely
permissive Open Supply license, and the weights can be found for anyone to obtain and check out.
That is totally different from different fashions like LLaMA that, whereas their weights are freely accessible, their license
restricts LLaMAs utilization to solely “Non-Industrial” use circumstances like educational analysis or private tinkering.
Meaning if you would like to take a look at LLaMA you may must get entry to a robust GPU to run it or use a
volunteer-run service like KoboldAI. You may’t simply go to a web site like you possibly can with
ChatGPT and count on to begin feeding it prompts. (Not less than with out working the chance of Meta sending you a DMCA takedown
request.)
Proof-of-Idea to reveal Cerebras Coaching {Hardware}
The actual motive that this mannequin is being launched is showcase the loopy silicon that Cerebras has been spending years
constructing.
These new chips are spectacular as a result of they use a silicon structure that hasn’t been deployed in manufacturing for AI
coaching earlier than: As a substitute of networking collectively a bunch of computer systems that every have a handful of NVIDIA GPUs, Cerebras
has as a substitute “networked” collectively the chips on the die-level.
By releasing Cerebras-GPT and displaying that the outcomes are similar to current OSS fashions, Cerebras is ready to
“show” that their product is aggressive with what NVIDIA and AMD have in the marketplace right now. (And wholesome
competitors advantages all of us!)
Cerebras vs LLaMA vs ChatGPT vs GPT-J vs NeoX
To place it in easy phrases: Cerebras is not as superior as both LLaMA or ChatGPT (gpt-3.5-turbo). It is a
a lot smaller mannequin at 13B parameters. (Cerebras is ~6% of the dimensions of GPT-3 and ~25% of the dimensions of LLaMA’s
full-size, 60B parameter mannequin.)
That does not imply that it is ineffective although. As you may see from the info launched within the Cerebras paper, this mannequin
remains to be a big development over earlier Open Supply fashions like GPT-2 (1.5B),
[GPT-J (6B)]
(https://huggingface.co/EleutherAI/gpt-j-6B) or GPT NeoX (20B).
For anyone constructing round AI that does not wish to rely on
OpenAI’s monopoly, this can be a welcome addition to the AI
panorama. (Even when it is solely actually an incremental step ahead, as you may see in a second.)
Benchmark Comparability

It is a bit troublesome to check apples-to-apples between all of those totally different fashions, however I did my greatest to squeeze
the info collectively in a approach that made it simpler to know.
As you possibly can see from this desk: Cerebras-GPT is roughly the identical as GPT-J and GPT NeoX, and typically even
worse, for duties like OpenBookQA and ARC-c (“advanced”). From what these assessments really contain, it appears
that each of these duties depend on some quantity of “widespread sense” information to get proper (determing the right reply
requires utilizing information that is not included within the query wherever).
…after which there may be GPT-4 crushing all the pieces else on this desk!
Is Cerebras-GPT value utilizing?
Based mostly on the info above, it is not likely significantly better than any current OSS fashions, so it is exhausting to say if it is a
better option than GPT-J or GPT NeoX for any duties. Maybe with some fine-tuning the mannequin might be able to carry out
higher than both of these, however I will let any individual extra certified than me reply that query as a substitute!
