Technically, he is right. But OpenAI was the first to find the winning formula and make it famous.

What do you mean by "winning formula" in this sentence?

Not the parent, but to me it generally means 1 million (likely non-dev, regular people) users in 5 days.

For me personally: I have had success asking for code snippets and general brainstorming in areas which are not my forte, all the while using a very nice and clean UI.

The spell out is a limitation of the way the model works, it predicts the text word by word.

Yes I get that. But just speed the god damn thing up.

The god damn thing has to do 175B multiply and add operations for each one of your words.

What would you change to the UX and design to make it even better?

Entering and editing text on a small touchscreen with it is a pretty bad experience. The keyboard covers the text, linebreaks can't be entered without pasting, viewing the output requires closing the keyboard. None of these are problems to the same degree in say Discord's mobile/tablet UI.

It has some issues when you edit a prompt that has very long text, it will snap to the end when you type losing focus.

> OpenAI's really interesting approach to GPT That's the issue though, Yann LeCun is specifically referring to ChatGPT as the standalone model, not the GPT family since a lot of models at Meta, Google, DeepMind are based on a similar approach. His point is that ChatGPT is a cosmetic additional training with prompt with a nice interface, but not a fundamentally different model than stuff we've have had for +2-3 years…

ChatGPT is build on GPT-3. GPT-3 was a big NLP development. The paper has 7000+ citations: https://arxiv.org/abs/2005.14165 It was a big deal in the NLP space. It wasn't a 'cosmetic' improvement over existing NLP approaches.

Respectfully I don't think you read my comment. GPT3 != ChatGPT. ChatGPT is built on GPT-3 and is not breaking new ground. GPT3 is 3 years old and was breaking new ground in 2020 but Meta/Google/DeepMind all have LLM of their own which could be turned into a Chat-Something.

That's the point LeCunn is making. He's not out there negating that the paper you linked was ground-breaking, he's saying that converting that model into ChatGPT was not ground-breaking from an academic standpoint.

Yes, but along that reasoning the criticism that "ChatGPT is not particularly innovative" is a bit disingenuous in the sense that the general public has never had easy access to these models until ChatGPT arrived. Besides, even though the newer GPT models presumably just extended earlier ones with similar techniques but better hardware and data, it wasn't a foregone conclusion how powerful (from the user perspective)…

I don't think the point here is to downplay the significance of ChatGPT as a product, but to point out that OpenAI is likely not uniquely resourced in this regard. If anything, it sounds like what they're trying to say is that ChatGPT is only the tip of the iceberg, and the reason why it came out of OpenAI and not Meta or Google is more a function of other factors like reputational damage, etc. The headline does hit…

Meta should RLHF or RLAIF their model Galactica and put it up again. It was interesting to use to sample ideas. Just tune it down a bit with the confident language.

Looks like I missed that part. But I would not call the summarization faithful to the source. The garbage bit is basically made up.

@belval -- sorry, can't reply directly. I understand what you're saying -- fair enough! I appreciate the clarification.

A tweet isn't worth a news article. Geeze.

That seems to be a lot of news articles these days. I'm not particularly excited by ChatGPT, but the mercenary in me is impressed at the investment from MS it generated. From a business perspective, it accomplished "and profit!". Whether it pays dividends or reaches a richer/more-sophisticated milestone is to be seen. Personally, I think it'll muddy and flood the "bullshit" & truthiness layer pervading news, social m…

It is a tool, like a knife. You can use it to reword your rough notes into an article, or to generate spam and fake news. It is a great idea fountain, but you need to filter everything with your own head to make anything useful of it.

He's not wrong. The key ingredient in ChatGPT is not brilliance but capital. It takes a lot of money not just to do the raw training but to get all the data together and process everything. There's no break through insights that make ChatGPT work, just a lot of consolidated wealth. The hacker part of me finds AI less and less interesting for this reason. We're seeing what the limits of pouring resources into the prob…

When language models run out of more trillions of words to train, there is one way ahead - we need to generate more. But wait, you might say, garbage in garbage out. It won't work.

Normally it wouldn't, but we add an extra ingredient here. We get a validation signal. This is problem specific, but for code it would mean to integrate the LM with a compiler and runtime so it can iterate until it solves the task, step by step. For other tasks it could mean hooking the AI to simulators, games and robots to solve tasks. It is also possible to use LLMs as simulators of text.

Basically doing Reinforcement Learning with a Language Model and not just for human preferences, but for problem solving on a grand scale. Collect data from problem solving, train on it, and iterate. It costs just electricity, but LLMs can make their own data. Anthropic's Constitutional AI which is RLAIF - reinforcement learning from AI feedback is proof it can be done.
