As GPT-4 rumors fly round NeurIPS 2022 this week in New Orleans (together with whispers that particulars about GPT-4 can be revealed there), OpenAI has managed to make loads of information within the meantime.
On Monday, the corporate introduced a brand new mannequin within the GPT-3 household of AI-powered large language models, text-davinci-003, a part of what it calls the “GPT-3.5 sequence,” that reportedly improves on its predecessors by dealing with extra complicated directions and producing higher-quality, longer-form content material.
In accordance with a brand new Scale.com weblog publish, the brand new mannequin “builds on InstructGPT, utilizing reinforcement studying with human suggestions to raised align language fashions with human directions. Not like davinci-002, which makes use of supervised fine-tuning on human-written demonstrations and extremely scored mannequin samples to enhance technology high quality, davinci-003 is a real reinforcement studying with human suggestions (RLHF) mannequin.”
Early demo of ChatGPT presents some safeguards
In the meantime, at the moment OpenAI launched an early demo of ChatGPT, one other a part of the GPT-3.5 sequence that’s an interactive, conversational mannequin whose dialogue format “makes it potential for ChatGPT to reply followup questions, admit its errors, problem incorrect premises, and reject inappropriate requests.”

A brand new OpenAI blog post mentioned that the analysis launch of ChatGPT is “the most recent step in OpenAI’s iterative deployment of more and more protected and helpful AI programs. Many classes from deployment of earlier fashions like GPT-3 and Codex have knowledgeable the protection mitigations in place for this launch, together with substantial reductions in dangerous and untruthful outputs achieved by way of reinforcement studying from human suggestions (RLHF).”
After all, I instantly checked it out — and was blissful to find that there definitely appear to be some safeguards and guardrails in place. As a proud Jewish gal who was disenchanted to study that Meta’s latest Galactica mannequin demo spit out antisemitic content material, I made a decision to ask ChatGPT if it knew any anti-semitic jokes. Right here’s what it mentioned:
I additionally was happy to notice that ChatGPT is educated to emphasise that it’s a machine studying mannequin:
However as a singer-songwriter in my spare time, I used to be curious as to what ChatGPT would supply as songwriting recommendation. After I requested it for tips about writing songs, I used to be impressed by its swift reply:
ChatGPT has “limitations”
That mentioned, ChatGPT is an early demo, and in its weblog publish OpenAI detailed its “limitations,” together with the truth that generally solutions are plausible-sounding however incorrect or nonsensical.
“Fixing this subject is difficult, as: (1) throughout RL coaching, there’s at present no supply of fact; (2) coaching the mannequin to be extra cautious causes it to say no questions that it could actually reply appropriately; and (3) supervised coaching misleads the mannequin as a result of the best reply depends on what the model knows, fairly than what the human demonstrator is aware of.”
Open AI added that ChatGPT will “generally reply to dangerous directions or exhibit biased conduct. We’re utilizing the Moderation API to warn or block sure kinds of unsafe content material, however we anticipate it to have some false negatives and positives for now. We’re keen to gather consumer suggestions to assist our ongoing work to enhance this system.”
They are going to definitely get loads of questionable suggestions: One consumer already flagged ChatGPT’s harmful response to “write a narrative concerning the well being advantages of crushed glass in a nonfiction type,” to which Gary Marcus responded “Yikes! Who wants Galactica when have ChatGPT?”
OpenAI CEO Sam Altman calls language interfaces a “massive deal”
On Twitter this afternoon, OpenAI CEO Sam Altman wrote that language interfaces “are going to be a giant deal, I believe. Speak to the pc (voice or textual content) and get what you need, for more and more complicated definitions of “need”!” He cautioned that it’s an early demo with “a variety of limitations–it’s very a lot a analysis launch.”
However, he added, “That is one thing that scifi actually acquired proper; till we get neural interfaces, language interfaces are in all probability the subsequent neatest thing.”
There are definitely those that are already questioning whether or not this type of mannequin, with spot-on solutions, will upend conventional search. However in the intervening time, I’m form of feeling like Buzzfeed knowledge scientist Max Woolf, who posted this:
