- blackbear_ 6y agoJust because many more humans spent many more years and many more $$$ building GPT-3 for your convenience.
- fastball 6y agoRight, but GPT-3 can be used generally. That's the difference. It scales because you don't need to build an entirely new model for each different use case. You just change the prelude and use it for something new.
- sillysaurusx 6y agoIt sounds like a big deal. What a tempting idea. And a colleague was mildly annoyed with me for how unimpressed I seemed. But you have to understand, the use cases you mention are shallow and limited. The heart of GPT, the fine-tuning, is gone. And it looks like even OpenAI gave up on letting users fine-tune, because it means they essentially do build an entirely new, expensive model for each use case. I wanted to make an HN Simulator, the way that https://www.reddit.com/r/SubSimulatorGPT2/ https://www.reddit.com/r/SubSimulatorGPT2/ works. But that's far beyond the capabilities of metalearning (the idea that you describe).
- fastball 6y agoI think the onus is on you to prove that the use cases are shallow and limited. I've seen GPT-3 already being used for diverse and interesting ideas that would not have occurred to me personally. However, even if they are, the point stands: currently, there are teams of people at companies all over the world tuning models for these shallow and limited use-cases. GPT-3 can replace them all, without OpenAI needing to invest another cent in training for a particular customer's use-case. That is in fact game-changing for the ML/DL world and current applications thereof. Is it AGI? Obviously not. But the vast majority of ML applications don't need to be.
- sillysaurusx 6y agoWhat other proof would you like, other than an example of what I wanted to do and can't? (https://www.reddit.com/r/SubSimulatorGPT2/ https://www.reddit.com/r/SubSimulatorGPT2/ but for HN.) For a more extensive rebuttal, I wrote one here. https://news.ycombinator.com/item?id=23346972 https://news.ycombinator.com/item?id=23346972 Though that was more a rebut of GPT in general as a path to AGI than metalearning in particular for generating memes.
- fastball 6y agoGPT-3 not being suitable for your particular use case does not mean that all use cases are shallow and limited? That being said, I'm not sure I understand why you can't use GPT-3 to make an HN simulator.
- ponker 6y agoWhat are the diverse and interesting ideas that would not have occurred to you personally?

The counterpoint is that it would be significantly cheaper AND have better performance to fine-tune models to each customer's use case than it is to just run GPT-3 at inference.
- fastball 6y agoClearly that is not true for the commenter that started this thread.
- Traubenfuchs 6y agoHow did they react to this as humans with human pride? Sounds painful.
- ozorOzora 6y agoAs GP's declarations are backed by air, we can speculate they are self-reported statements by people working on non-business-centric applications. edit: GP giving more downvotes than proofs
- Voloskaya 6y agoSo GPT-3 didn't replace your 2 ML engineers, OpenAI did. GPT-3 didn't build itself.
- computerphage 6y agoThe iPhone didn't replace your flip phone, apple did. The iPhone didn't build itself.
- Voloskaya 6y agoYes except they were saying the iPhone replaced Nokia's engineers. GPT-3 is not doing what the ML engineers were doing (building models), GPT-3 is the end goal. The company just decided to outsource the work to OpenAI and pay a monthly fee to them instead of salaries to their ML engineers. "We have already found several use cases for it, one of which replaces 2 ML engineers." -> Clearly makes it sounds like GPT-3 can do the job their ML engineers were doing.
- DavidSJ 6y agoFrom a business perspective, this is an irrelevant distinction. The requirement was satisfied in a different way, i.e. the engineers satisfying the requirement were replaced by GPT-3, the tool which satisfies the requirement. I think everyone understood that.
- Voloskaya 6y agoThe thread is not about business perspective, it's about the hype around what GPT-3 is and is not able to do. One thing GPT-3 is not able to do for example, is replacing 2 ML engineers to build a GPT-3 like model. But OpenAI can do that.
- dwaltrip 6y agoIt’s not clear what you are trying to say.
- ApicalDendrite 6y agoWere there any concerns about GPT-3's latency? It looks like it takes a long time for online use cases.
- landryl 6y agoThat's interesting, GPT-3 can do classification too? Or did I misunderstood and you meant your engineers used classification to build a language model that didn't perform as well as GPT-3 (which is less surprising indeed) ?
- wongarsu 6y agoGPT-3 can do classification. For example you can give it a prompt like "Hacker News is a website. Excel is a Windows program. Visual Studio is a Windows program. Safari is a Mac program. CPU-Z is", and even GPT2 will complete this with "a Windows program" (with GPT2 you need to try multiple times, discard useless results and average what's most common, but it works and is straight-forward to automate).
