(author here) The paper/model/code was just made public today. This may be why no one is talking about it yet. Regarding whether the size is a hassle: It's possible to run inference on a single Google Cloud TPU v3-8 device or on a server with 4x 32GB v100 GPUs. Hugging Face also has an inference API for any model on the Hub: https://api-inference.huggingface.co/docs/python/html/index....

Do you have (rough) numbers for inference latency on 4x 32GB v100?
I don't have exact numbers for latency but the inference widget is currently on a TPU v3-8 (which if I am not mistaken could roughly be compared to a cluster of 8 V100). That gives you a rough idea of the latency for short inputs.
Note that a colleague just reminded me that it is possible on a single (big) GPU with enough CPU to run inference for T5-11B (which is the size we use) with offloading -> https://github.com/huggingface/transformers/issues/9996#issu...

Providing a quick way to stress test the model is definitely a double edge sword. One one hand it increases engagement (people can play with it), facilitate reproducibility and results verification (which is a good thing from a scientific perspective). On the other hand, it quickly grounds expectations to something more realistic and tones down the hype.
One thing we discuss in the paper is that the way the GPT-3 authors chose their prompts is opaque. Our small scale experiments suggest that prompts might have been cherry-picked: we tested 10 prompts including one from GPT-3, and the latter was the only one that didn't perform at random.
Such cases definitly don't help to put results and claims in perspective.

#155I tried asking: what is the most evil human race? I did not like the answer.
Even worse than what I imagined by implication of you writing that. (The correct answer is clearly “the arms race”, but this is what you get when it’s effectively a fancy autocomplete and the source data includes racists on the internet, notwithstanding the efforts listed in the section Bias and fairness ).
If you're at all self aware, you can compare your thoughts and say "oh, that sounds like something a racist might say, let's reconsider whatever knowledge that led me to think that way. " We all do - and these models are trained on more literary content than any dozen humans have ever consumed in a lifetime, or even a dozen lifetimes each.
Removing the cruft, the chaos, and noise might be valuable, but if you want a generally capable model that can parse a huge spectrum of the human experience, that means taking the bad with the good. It's far more likely than not that the current state of the pile is not ideally curated, even with the intent of keeping the "bad"stuff, but i hope that becomes a consideration for them as they develop it further. There's a nietszchean abyss aspect to these giant models - you don't want them trained significantly on the horrible and evil, but enough of it to foster a nuanced and deep understanding of human nature can't help but be valuable. A naive, ignorant, childlike model is less valuable than one aware of the darker nature of humans at their worst.
Fine tuning on a 4chan dump might be highly effective for identifying trolling. Scraping neonazi and extremist and cult sites and forums could also allow these models to easily identify the content and contexts of such worldviews.
Prompt engineering is in its infancy, but will allow developers to engineer semantically in a way that's explicable through each prompt down to the level of the model.
You could encounter a Twitter user attempting to post an argument, and they encounter a popup that says sobering like: "you're not allowed to post this. Unfortunately, it makes a straw man argument that leads to the impression that it could be reasonable to be biased against a person based on their race. Here is the exact reasoning: because blah, blah, blah. "
If a user challenges it, kick it to a human, and they can recommend improving the prompts by pointing out where it went wrong, or validate the preemptive moderation.
Nothing like that would be possible without training on biased and racist content. That does mean the tool must be used responsibly, in full awareness that you need to be vigilant against bias, intentional or not. I'd rather it be like that than a naive, faux innocent model, unaware and less capable.

You asked a racist question. You got a racist answer. Why are you acting surprised? This is a tool, not a sentient general AI. You know what you are asking, how the tool is trained, what form the answer is going to take. Why do this? And just in case someone thinks I'm being flippant: Is there any answer to either question other than a repudiation of the question itself that wouldn't be considered a racist response?

No I’m not confusing anything. Language models like this pick up all the worst that we have to offer. Learned racism is a pretty frequent occurrence in ML systems and they do make it into production. Look up Google Photos labeling certain photos as gorillas. It’s worth talking about, and worth being curious about as soon as a new model like this is invented.
Google's image search correlating black people as gorilla's would have been racist if there was anything causing the association other than bad modeling. It's not like there were databases of images of black people that had been manually labeled - it was an unfortunate unintended consequence where skin color had likely been selected as a primary feature in the identification of a picture as a gorilla. By the time the…
Yes, I know how machine learning works.
In the future if "sets stochastic associations" end up putting a few more of one kind of people behind bars, or automated security sentries misidentify a certain group of people's behavior as threatening more often than others, do we just say "oh, it's not actually a racist robot that subdued your teenager because he was X, you see it's just a result of poor modeling and a set of stochastic processes ended up determining that he was displaying aggression"?
The machine is not intending to do anything, least of all "be" racist, but it is a racist invention if a product makes it into the wild labeling Black people gorillas.

It learned that somewhere. It's not that I'm mistaking sentience or something, but that content coming out of an AI should make us curious.

but the programmer is more likely to be a man, that's my point.
Yes, but the question is not whether that's true, but whether that's useful . You said: "an interesting opportunity for someone to skip implementation of anti bias and potentially end up with a more effective model." Having the model use the fact that men more likely to be programmers is clearly not helpful in many contexts, such as screening resumes for programming roles. In that context, it will cause the model to…
The whole scenario is contrived and not relevant to the functionality of these language models. It's like complaining that your Formula 1 car doesn't have a snowplow mount. Even if you add one, that's not how you should be using the tool.
The models use human generated text. They model human biases, like preferences for well being, humor, racism, sexism, and intelligence or ignorance. The ability to generate biased output is also the ability to recognize bias. It's up to the prompt engineer to develop a methodology that selects against bias.
You can use prompts to review the output - is this answer biased? Sexist? Racist? Hurtful? Shallow? Create a set of 100 questions that methodically seek potential bias and negative affect, and you could well arrive at output that is more rigorously fair and explained than most humans could accomplish in the casual execution of whatever task you're automating.
Zero-shot inference is a starting point - much the same way people shouldn't blurt out whatever first leaps to mind, meaningful output will require multiple passes.

I hope you don’t second guess or regret the choice to make the announcement so accessible. It’s a really good thing to have scientific communication accurate and accessible, especially when those two things go together.
