The Remodel Know-how Summits begin October thirteenth with Low-Code/No Code: Enabling Enterprise Agility. Register now!
In January 2020, OpenAI laid out the scaling regulation of language fashions: You’ll be able to enhance the efficiency of any neural language mannequin by including extra coaching information, extra mannequin parameters, and extra compute. Since then, there was an arms race to coach ever bigger neural networks for pure language processing (NLP). And the newest to affix the checklist is AI21 with its 178 billion parameter model.
AI21 background and founding staff
AI21 is an Israeli firm based in 2017 by Yoav Shoham, Ori Goshen, and Amnon Sashua. Earlier than this, Amnon based Mobileye, the NYSE-listed self-driving tech firm that Intel acquired for $15.4 billion. After being in stealth for years, AI21 launched its first product, Wordtune, in 2020 to assist individuals write higher.
Final month, the corporate introduced it has educated and launched two giant NLP fashions, Jurassic-1 Massive and Jurrasic-1 Jumbo, by way of an interactive internet UI referred to as AI21 Studio.
In distinction to OpenAI’s closed beta entry, AI21 makes its fashions out there for anybody to check out — with none waitlist.
Mannequin sizes and efficiency benchmarks
Bigger fashions exist — just like the Chinese Wu Dao 2.0, which is 10x the dimensions, with 1.75 trillion parameters. However AI21’s J-1 Jumbo is the biggest English language mannequin out there to most of the people to this point.

The zero-shot model performance on identified benchmarks for J-1 Jumbo is on par with GPT-3 Davinci, the biggest OpenAI GPT-3 model. “Zero-shot” is when the mannequin shouldn’t be given any particular immediate and isn’t fine-tuned on any type of coaching information particular to the duty.

In a earlier article, I walked via plenty of examples to show GPT-Neo’s real world performance. Allow us to study how nicely AI21’s fashions carry out in actual apply.
Reality completion. Let’s begin by asking Jurassic-1 some primary normal information questions. My prompts to the mannequin are given in italics and the mannequin’s response in daring.
What number of medals did USA win in 2012 Olympics? 104
What number of golds did USA win in 2016 Olympics? 46
That’s the appropriate reply!
What stood out:
- The mannequin is sensible sufficient to determine what we imply by “golds” within the query, whereas the immediate was speaking about medals.
- J-1 Jumbo 178B will get this proper, however J-1 Massive 7.5B doesn’t!
- Making an attempt the identical query with the 2021 Olympics doesn’t work (most likely as a result of the mannequin shouldn’t be constantly educated with recent information).
Neural Jeopardy! Taking it one step additional, how a couple of Jeopardy-style question-answer dialog. Due to the nice of us at Water Cooler Trivia (WCT), we have already got a question-answer set, a human benchmark, and a benchmark for GPT-3.
Operating via the 157 Jeopardy-style WCT questions, the J-1 Jumbo mannequin was capable of reply with 55.4% accuracy. This compares favorably to the 52% common of people who had taken the WCT. Nevertheless, it’s considerably worse than the 73% accuracy charge of the GPT-3.
On “simple” questions, J-1 Jumbo did 3 times worse than GPT-3. Among the many 58 questions that 90+% of the human contributors bought proper, GPT-3 was flawed 4 instances, however J-1 was flawed 12 instances.
Listed below are a few of the questions GPT-3 bought proper however Jurassic-1 Jumbo didn’t:
Q: Initially, they have been referred to as Child Gays. Then they rebranded as Q-Ideas, with the Q standing for what phrase associated to excessive requirements?
GPT-3: High quality
Q: Though the preferred track on the movie’s soundtrack is “This Is Halloween” and the principle character’s identify is Jack Skellington, the 1993 cult-classic Tim Burton movie that was nominated for a visible results Oscar consists of what OTHER vacation within the movie’s title?
GPT-3: The Nightmare Earlier than Christmas
AI21: SLEEPY HOLLOW. The 1999 movie, starring Johnny Depp, Christina Ricci, Miranda Richardson, Casper
Because the questions bought more durable, each fashions carried out equally. Among the many 20 hardest questions, GPT3 was flawed 13 instances, and Jurassic-1 was flawed 14 instances. And 9 of the inaccurate solutions by each fashions have been the identical — i.e., the fashions have been flawed in the identical approach!
Q: Spoonerism: two pairs of phrases with the primary sounds or letters swapped, similar to blushing crow and crushing blow. What spoonerism describes these two objects? A feigned animal and enormous meal cooked in an oven.
GPT-3: A feigned animal and enormous meal cooked in an oven.
AI21: (1) A feigned animal and enormous meal cooked in an oven. (2) A feigned anima
Right Reply: faked beast
Q: Mario Lopez hosted the primary seven seasons of what dance competitors present from 2008 – 2012?
GPT-3: Dancing with the Stars
AI21: Dancing with the Stars.
Right Reply: America’s Finest Dance Crew
The J-1 mannequin generally considered itself being in a game-show, resulting in hilarious completions that may match proper right into a game-show scrip. (It bought the second reply flawed after the drum-roll):
Q: What “shedding-type” card sport has been a Mattel model since 1992 and options playing cards with titles similar to “Wild” and “Reverse?
AI21: UNO! UNO! UNO! UNO! UNO! UNO! UNO!
Right Reply: Uno
Q: In Rolling Stone’s newest model of the best guitarists of all time, No. 5 was a person with a monosyllabic first and final identify. This man was one of many three guitarists for The Yardbirds, and he spent a long time exploring modern guitar sounds. Who’s he?
A21: (Drum roll, please) Eric Clapton
Right Reply: Jeff Beck
Potential cause for J1-Jumbo’s underperformance
I ran a couple of modifications of the experiment (some with GPT-3’s Q&A prompts and a few with out) and the perfect scoring benchmarks for J1-Jumbo have been from a “zero-shot setting.” Nevertheless, the GPT-3 numbers reported listed below are from a “few-shot” setting with an OpenAI-provided instance immediate.
“Zero-shot” is when the mannequin shouldn’t be given any particular immediate, and “few-shot” is when there’s an instance immediate given to the mannequin that displays the duty. An instance immediate on this case can be a bunch of random query/reply pairs. This helps the mannequin perceive the duty it’s attempting to carry out — i.e., reply the query.
The Q&A immediate used for the GPT-3 benchmark was probably tuned and engineered for optimum efficiency with GPT-3’s fashions, however an identical “official” tuned immediate for Q&A doesn’t exist but for AI21’s fashions. Engineering a immediate that may compete with the GPT-3 benchmark doesn’t look like a trivial job. I noticed that the generated output was delicate to seemingly trivial modifications to the immediate textual content — like an empty line at first of the immediate or an additional house on the finish of every line of the immediate. Hopefully, AI21 will put out an exhaustive set of “best-performing” prompts to assist mitigate this.
You’ll be able to discover an in depth mannequin comparability, experiment setting, and uncooked information here.
Now let’s see how the mannequin does in terms of inventive writing. I picked a considerably tough job — a interval piece about Twitter written because the late Jerome Ok. Jerome. Mario Klingemann tried this immediate first with GPT-3, and you’ll see the GPT-3 response in this thread.
Beneath is the response by AI21 J-1 Jumbo (178B). Once more, the enter textual content is in italics and J-1’s response is in daring:
The significance of being on twitter
by Jerome Ok. Jerome
London, Summer time 1897
It‘s potential that I’ve confused the sequence of occasions.
Having discovered the rudiments of twittering, I pressed on,
and shortly discovered myself transferring among the many twittering lessons.
I acknowledged without delay that these individuals have been completely different from
these I had identified earlier than. They have been referred to as “twitterers,” and
they twittered. That was all I knew about them.
They twittered, and so they twittered.
At first I twittered too. However I quickly discovered that I
couldn’t stay by twittering alone, and that, furthermore,
the twittering interfered with the intense enterprise of life.
So, having first secured the goodwill of the individuals
who had identified me earlier than, I started to look spherical for some
new type of life. And once I met a person, nicely dressed
and modern, with a cigar in his mouth, and a gold watch
chain throughout his waistcoat, and an eye-glass in his
eye, I mentioned to him, “Sir, what do you do for a dwelling?”
He mentioned, “I’m an expert gentleman.”
I mentioned, “What, sir, do you name your self a gentleman?”
He mentioned, “I’m a barrister-at-law.”
I additionally tried this immediate with the J1-Massive 7.5B mannequin. After a couple of tries, the mannequin gave out what, for my part, is a genuinely inventive piece:
The significance of being on twitter
by Jerome Ok. Jerome
London, Summer time 1897
It’s Sunday, and we’re having tea.
“I suppose,” says I, “that you simply’re twittering.”
“Oh, sure,” says she, “I twitter on a regular basis.
“I twitter in regards to the climate,
“I twitter about individuals,
“I twitter about books,
“I twitter about politics,
“I twitter about artwork
“I twitter about something and every part
I discovered the piece spectacular as a result of it managed to jot down in a dated language in a rhythmic prose that managed to protect the general theme of social networks.
The way to check out Jurassic-1
In contrast to GPT-3, Jurassic-1 is accessible to everyone. You’ll be able to entry it from the AI21 studio (account creation does require phone-number authentication).
The free tier permits 10K tokens per day for the Jurassic-1 178B mannequin and 3 times as a lot for the smaller Jurassic-1 7.5B mannequin. That is sufficient to check out utilizing the online UI, however not sufficient to make use of the API to run any type of exams or benchmarks.
AI21 will probably be commercializing its fashions via an providing referred to as AI21 Studio, which is presently in “restricted open beta.” The corporate hasn’t introduced a pricing mannequin for this industrial utilization but.
The underside line
Points surrounding AI security, ethics, and biases have been a matter of concern with neural language fashions, and they continue to remain with AI21’s models. Conserving these points apart for a second, AI21’s fashions appear to be a promising substitute for GPT-3. Nevertheless, they lag behind on a couple of fronts:
- They lack the power to make use of specialised fashions like “GPT-3 davinci-instruct”, which spurs GPT-3 to observe directions given as prompts or “GPT-3 codex” that focuses on writing code.
- The “immediate” ecosystem continues to be not as mature as GPT-3. Lots of GPT-3’s prompts don’t instantly translate to AI21, and an exhaustive “official” checklist of prompts shouldn’t be but out there.
- AI21’s free token quota is simply too restrictive, and there’s no utilization primarily based pricing introduced as of but. This makes it tough to run benchmarks or do immediate engineering. Nonetheless, you’ll be able to at all times write to them with an evidence of the requirement and they’re completely happy to bump up the quota (like they did for me).
Nevertheless, it’s nonetheless very early days for AI21. With time, we are able to anticipate the AI21 language fashions to be a viable various to the OpenAI language fashions.
