AI Gets Smarter, Safer, More Visual With GPT-4 Release, OpenAI Says

ChatGPT Plus subscribers can try it out now.

The hottest AI technology foundation, OpenAI’s GPT, got a big upgrade Tuesday that’s now available in the premium version of the ChatGPT chatbot.

The new GPT-4 can generate much longer strings of text and respond when people feed it images, and it’s designed to do a better job avoiding artificial intelligence pitfalls visible in the earlier GPT-3.5, OpenAI said Tuesday. For example, when taking bar exams that attorneys must pass to practice law, GPT-4 ranks in the top 10% of scores compared to the bottom 10% for GPT-3.5, the AI research company said.

GPT stands for Generative Pretrained Transformer, a reference to the fact that it can generate text on its own and that it uses an AI technology called transformers that Google pioneered. It’s a type of AI called a large language model, or LLM, that’s trained on vast swaths of data harvested from the internet, learning mathematically to spot patterns and reproduce styles.

OpenAI has made its GPT technology available to developers for years, but ChatGPT, which debuted in November, offered an easy interface that yielded an explosion of interest, experimentation and worry about the downsides of the technology. ChatGPT is free, but it falter when demand is high. In January, OpenAI began offering ChatGPT Plus for $20 per month with assured availability and, now, the GPT-4 foundation.

GPT-4 advancements

«In a casual conversation, the distinction between GPT-3.5 and GPT-4 can be subtle. The difference comes out when the complexity of the task reaches a sufficient threshold,» OpenAI said. «GPT-4 is more reliable, creative and able to handle much more nuanced instructions than GPT-3.5.»

Another major advance in GPT-4 is the ability to accept input data that includes text and photos. OpenAI’s example is asking the chatbot to explain a joke showing a bulky decades-old computer cable plugged into a modern iPhone’s tiny Lightning port.

Another is better performance avoiding AI problems like hallucinations — incorrectly fabricated responses, often offered with just as much seeming authority as answers the AI gets right. GPT-4 also is better at thwarting attempts to get it to say the wrong thing: «GPT-4 scores 40% higher than our latest GPT-3.5 on our internal adversarial factuality evaluations,» OpenAI said.

GPT-4 also adds new «steerability» options. Users of large language models today often must engage in elaborate «prompt engineering,» learning how to embed specific cues in their prompts to get the right sort of responses. GPT-4 adds a system command option that lets users set a specific tone or style, for example programming code or a Socratic tutor: «You are a tutor that always responds in the Socratic style. You never give the student the answer, but always try to ask just the right question to help them learn to think for themselves.»

«Stochastic parrots» and other problems

OpenAI acknowledges significant shortcomings that persist with GPT-4, though it also touts progress avoiding them.

«It can sometimes make simple reasoning errors … or be overly gullible in accepting obvious false statements from a user. And sometimes it can fail at hard problems the same way humans do, such as introducing security vulnerabilities into code it produces,» OpenAI said. In addition, «GPT-4 can also be confidently wrong in its predictions, not taking care to double-check work when it’s likely to make a mistake.»

Large language models can deliver impressive results, seeming to understand huge amounts of subject matter and to converse in human-sounding if somewhat stilted language. Fundamentally, though, LLM AIs don’t really know anything. They’re just able to string words together in statistically very refined ways.

This statistical but fundamentally somewhat hollow approach to knowledge led researchers, including former Google AI researchers Emily Bender and Timnit Gebru, to warn of the «dangers of stochastic parrots» that come with large language models. Language model AIs tend to encode biases, stereotypes and negative sentiment present in training data, and researchers and other people using these models tend «to mistake … performance gains for actual natural language understanding.»

OpenAI, Microsoft and Nvidia partnership

OpenAI got a big boost when Microsoft said in February it’s using GPT technology in its Bing search engine, including a chat features similar to ChatGPT. On Tuesday, Microsoft said it’s using GPT-4 for the Bing work. Together, OpenAI and Microsoft pose a major search threat to Google, but Google has its own large language model technology too, including a chatbot called Bard that Google is testing privately.

Microsoft uses GPT technology both to evaluate the searches people type into Bing and, in some cases, to offer more elaborate, conversational responses. The results can be much more informative than those of earlier search engines, but the more conversational interface that can be invoked as an option has had problems that make it look unhinged.

To train GPT, OpenAI used Microsoft’s Azure cloud computing service, including thousands of Nvidia’s A100 graphics processing units, or GPUs, yoked together. Azure now can use Nvidia’s new H100 processors, which include specific circuitry to accelerate AI transformer calculations.

Artemis II Astronauts Are Using iPhones to Capture Stunning Space Images

After smartphones were cleared by NASA for space missions, the crew members of the Integrity spacecraft are beaming back lots of iPhone photos.

The four astronauts aboard the Integrity spacecraft now headed home from their historic arc around the moon really are like the rest of us: Sometimes they reach for their smartphones to snap photos.

For the Artemis II mission, iPhone 17 Pro Max phones have been used to capture photos inside the capsule of the astronauts pondering the views of Earth and working on mission objectives. (Technically, NASA refers to them as PCDs – personal computing devices.)

Smartphones were cleared for use in space for the first time in February. In a post on X, NASA Administrator Jared Isaacman wrote, «We are giving our crews the tools to capture special moments for their families and share inspiring images and video with the world.»

Early in the mission, Commander Reid Wiseman snapped a pair of photos looking out the window with Earth behind him. Mission specialist Christina Koch and her dynamic curls in zero-gravity also captured a pensive view looking out over the planet. All three were made using the front camera — because wouldn’t you want to grab a selfie if you were in space?

The iPhone 17 Pro’s rear cameras are pulling their own weight during the mission, too. During the live broadcast as the crew approached the moon, Wiseman took a photo of the moon’s surface using the iPhone’s telephoto camera at 8x zoom. He turned the screen toward one of the video cameras mounted inside the spacecraft, creating an image of the moon’s surface alone against the darkness of the unlit cabin, with the iPhone’s signature rounded edges and Dynamic Island cutout at the top.

The main photo workhorses on this trip are a Nikon D5 DSLR and a Nikon Z9. The D5 is a model that has been used on several space excursions, and the Z9 is onboard as an experimental camera.

For NASA missions, every piece of equipment must be tested and certified, which is why the previously-approved D5 has a secure spot. Cameras must be resistent to space environmental factors like radiation, and safe if they’re floating around the capsule. However, the iPhones in space now are off-the-shelf models, according to a report by Jackie Watties of CNN.

The moon flyby was especially photo-intensive, with astronauts switching places several times so that two were always at windows with cameras and relating what they could see with their eyes. This photo of mission specialist and Canadian Space Agency astronaut Jeremy Hansen taking images using one of the Nikon cameras shows how some windows have camera shrouds attached. The shroud ensures that light from the interior isn’t reflected in the glass.

In a particularly relatable photo, Hansen is also using the front-facing camera of a white iPhone 17 Pro — as a portable mirror while he shaves. As the (modified) saying goes, the best selfie screen is the one you have with you.

The iPhone 17 Pro isn’t the first Apple product to go into space. Crew members have taken iPods, iPads and AirPods on missions since the Space Shuttle era. The Mac Portable even went up on a shuttle (and revealed that its trackball in zero-G isn’t the best option).

An Apple representative didn’t immediately respond to a request for comment.
