The company behind the ChatGPT chatbot has rolled out its latest artificial intelligence model, GPT-4, in the next step for a technology that91裸聊视频檚 caught the world91裸聊视频檚 attention.
The new system can figure out tax deductions and answer questions like a Shakespearan pirate, for example, but it still 91裸聊视频渉allucinates91裸聊视频� facts and makes reasoning errors.
Here91裸聊视频檚 a look at San Francisco-based startup OpenAI91裸聊视频檚 latest improvement on the generative AI models that can spit out readable text and unique images:
WHAT91裸聊视频橲 NEW?
OpenAI says GPT-4 91裸聊视频渆xhibits human-level performance.91裸聊视频� It91裸聊视频檚 much more reliable, creative and can handle 91裸聊视频渕ore nuanced instructions91裸聊视频� than its predecessor system, GPT-3.5, which ChatGPT was built on, OpenAI said in its announcement.
In an online demo Tuesday, OpenAI President Greg Brockman ran through some scenarios that showed off GPT-491裸聊视频檚 capabilities that appeared to show it91裸聊视频檚 a radical improvement on previous versions.
He demonstrated how the system could quickly come up with the proper income tax deduction after being fed reams of tax code 91裸聊视频� something he couldn91裸聊视频檛 figure himself.
91裸聊视频淚t91裸聊视频檚 not perfect, but neither are you. And together it91裸聊视频檚 this amplifying tool that lets you just reach new heights,91裸聊视频� Brockman said.
WHY DOES IT MATTER?
Generative AI technology like GPT-4 could be the future of the internet, at least according to Microsoft, which has invested at least $1 billion in OpenAI and made a splash by integrating AI chatbot tech into its Bing browser.
It91裸聊视频檚 part of a new generation of machine-learning systems that can converse, generate readable text on demand and produce novel images and video based on what they91裸聊视频檝e learned from a vast database of digital books and online text.
These new AI breakthroughs have the potential to transform the internet search business long dominated by Google, which is trying to catch up with its own AI chatbot, and numerous professions.
91裸聊视频淲ith GPT-4, we are one step closer to life imitating art,91裸聊视频� said Mirella Lapata, professor of natural language processing at the University of Edinburgh. She referred to the TV show 91裸聊视频淏lack Mirror,91裸聊视频� which focuses on the dark side of technology.
91裸聊视频淗umans are not fooled by the AI in `Black Mirror91裸聊视频� but they tolerate it,91裸聊视频� Lapata said. 91裸聊视频淟ikewise, GPT-4 is not perfect, but paves the way for AI being used as a commodity tool on a daily basis.91裸聊视频�
WHAT EXACTLY ARE THE IMPROVEMENTS?
GPT-4 is a 91裸聊视频渓arge multimodal model,91裸聊视频� which means it can be fed both text and images that it uses to come up with answers.
In one example posted on OpenAI91裸聊视频檚 website, GPT-4 is asked, 91裸聊视频淲hat is unusual about this image?91裸聊视频� It91裸聊视频檚 answer: 91裸聊视频淭he unusual thing about this image is that a man is ironing clothes on an ironing board attached to the roof of a moving taxi.91裸聊视频�
GPT-4 is also 91裸聊视频渟teerable,91裸聊视频� which means that instead of getting an answer in ChatGPT91裸聊视频檚 91裸聊视频渃lassic91裸聊视频� fixed tone and verbosity, users can customize it by asking for responses in the style of a Shakespearean pirate, for instance.
In his demo, Brockman asked both GPT-3.5 and GPT-4 to summarize in one sentence an article explaining the difference between the two systems. The catch was that every word had to start with the letter G.
GPT-3.5 didn91裸聊视频檛 even try, spitting out a normal sentence. The newer version swiftly responded: 91裸聊视频淕PT-4 generates groundbreaking, grandiose gains, greatly galvanizing generalized AI goals.91裸聊视频�
HOW WELL DOES IT WORK?
ChatGPT can write silly poems and songs or quickly explain just about anything found on the internet. It also gained notoriety for results that could be way off, such as confidently providing a detailed but false account of the Super Bowl game days before it took place, or even being disparaging to users.
OpenAI acknowledged that GPT-4 still has limitations and warned users to be careful. GPT-4 is 91裸聊视频渟till not fully reliable91裸聊视频� because it 91裸聊视频渉allucinates91裸聊视频� facts and makes reasoning errors, it said.
91裸聊视频淕reat care should be taken when using language model outputs, particularly in high-stakes contexts,91裸聊视频� the company said, though it added that hallucinations have been sharply reduced.
Experts also advised caution.
91裸聊视频淲e should remember that language models such as GPT-4 do not think in a human-like way, and we should not be misled by their fluency with language,91裸聊视频� said Nello Cristianini, professor of artificial intelligence at the University of Bath.
Another problem is that GPT-4 does not know much about anything that happened after September 2021, because that was the cutoff date for the data it was trained on.
ARE THERE SAFEGUARDS?
OpenAI says GPT-491裸聊视频檚 improved capabilities 91裸聊视频渓ead to new risk surfaces91裸聊视频� so it has improved safety by training it to refuse requests for sensitive or 91裸聊视频渄isallowed91裸聊视频� information.
It91裸聊视频檚 less likely to answer questions on, for example, how to build a bomb or buy cheap cigarettes.
Still, OpenAI cautions that while 91裸聊视频渆liciting bad behavior91裸聊视频� from GPT is harder, 91裸聊视频渄oing so is still possible.91裸聊视频�
