The company behind the ChatGPT chatbot has rolled out its latest artificial intelligence model, GPT-4, in the next step for a technology that害羞草研究所檚 caught the world害羞草研究所檚 attention.

The new system can figure out tax deductions and answer questions like a Shakespearan pirate, for example, but it still 害羞草研究所渉allucinates害羞草研究所� facts and makes reasoning errors.

Here害羞草研究所檚 a look at San Francisco-based startup OpenAI害羞草研究所檚 latest improvement on the generative AI models that can spit out readable text and unique images:

WHAT害羞草研究所橲 NEW?

OpenAI says GPT-4 害羞草研究所渆xhibits human-level performance.害羞草研究所� It害羞草研究所檚 much more reliable, creative and can handle 害羞草研究所渕ore nuanced instructions害羞草研究所� 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-4害羞草研究所檚 capabilities that appeared to show it害羞草研究所檚 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 害羞草研究所� something he couldn害羞草研究所檛 figure himself.

害羞草研究所淚t害羞草研究所檚 not perfect, but neither are you. And together it害羞草研究所檚 this amplifying tool that lets you just reach new heights,害羞草研究所� 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.

It害羞草研究所檚 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 they害羞草研究所檝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.

害羞草研究所淲ith GPT-4, we are one step closer to life imitating art,害羞草研究所� said Mirella Lapata, professor of natural language processing at the University of Edinburgh. She referred to the TV show 害羞草研究所淏lack Mirror,害羞草研究所� which focuses on the dark side of technology.

害羞草研究所淗umans are not fooled by the AI in `Black Mirror害羞草研究所� but they tolerate it,害羞草研究所� Lapata said. 害羞草研究所淟ikewise, GPT-4 is not perfect, but paves the way for AI being used as a commodity tool on a daily basis.害羞草研究所�

WHAT EXACTLY ARE THE IMPROVEMENTS?

GPT-4 is a 害羞草研究所渓arge multimodal model,害羞草研究所� which means it can be fed both text and images that it uses to come up with answers.

In one example posted on OpenAI害羞草研究所檚 website, GPT-4 is asked, 害羞草研究所淲hat is unusual about this image?害羞草研究所� It害羞草研究所檚 answer: 害羞草研究所淭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.害羞草研究所�

GPT-4 is also 害羞草研究所渟teerable,害羞草研究所� which means that instead of getting an answer in ChatGPT害羞草研究所檚 害羞草研究所渃lassic害羞草研究所� 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 didn害羞草研究所檛 even try, spitting out a normal sentence. The newer version swiftly responded: 害羞草研究所淕PT-4 generates groundbreaking, grandiose gains, greatly galvanizing generalized AI goals.害羞草研究所�

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 害羞草研究所渟till not fully reliable害羞草研究所� because it 害羞草研究所渉allucinates害羞草研究所� facts and makes reasoning errors, it said.

害羞草研究所淕reat care should be taken when using language model outputs, particularly in high-stakes contexts,害羞草研究所� the company said, though it added that hallucinations have been sharply reduced.

Experts also advised caution.

害羞草研究所淲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,害羞草研究所� 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-4害羞草研究所檚 improved capabilities 害羞草研究所渓ead to new risk surfaces害羞草研究所� so it has improved safety by training it to refuse requests for sensitive or 害羞草研究所渄isallowed害羞草研究所� information.

It害羞草研究所檚 less likely to answer questions on, for example, how to build a bomb or buy cheap cigarettes.

Still, OpenAI cautions that while 害羞草研究所渆liciting bad behavior害羞草研究所� from GPT is harder, 害羞草研究所渄oing so is still possible.害羞草研究所�
