CNN reported the model, the first in a series called OpenAI o1, was released 12 September 2024 as a preview, with the firm saying it expects regular updates and improvements. It will gradually become available to most ChatGPT users.

“We trained these models to spend more time thinking through problems before they respond, much like a person would,” the maker of ChatGPT said on its website. “Through training, they learn to refine their thinking process, try different strategies and recognize their mistakes.”

As examples of the new models’ power, OpenAI noted that they can be used by healthcare researchers to annotate cell sequencing data and by physicists to generate “complicated mathematical formulas needed for quantum optics.”

The potential of the new AI models was also highlighted by Noam Brown, a research scientist at the company.

“OpenAI’s o1 thinks for seconds, but we aim for future versions to think for hours, days, even weeks. Inference costs will be higher,” he posted on X Thursday, referring to the costs — such as higher energy bills — of using AI to make inferences from inputs. “But what cost would you pay for a new cancer drug? For breakthrough batteries?” he added.

AI’s massive thirst for energy was due to be discussed between senior White House officials and top US tech executives. Sam Altman, OpenAI CEO, Google Senior Executive Ruth Porat and Anthropic CEO Dario Amodei were expected to attend the meeting, a person familiar with the matter told CNN.

Although the technology may help solve thorny problems like cancer and the climate crisis, it poses equally complex challenges, including how to meet the significant demand for electricity required by advanced AI systems — which could worsen global warming. The new OpenAI model doesn’t yet have many of the features “that make ChatGPT useful,” the firm said, like browsing the web for information, and uploading files and images. “But for complex reasoning tasks this is a significant advancement,” it added.

In tests, OpenAI o1 performs similarly to PhD students on difficult benchmark tasks in physics, chemistry and biology, according to the company. And in a qualifying exam for the International Mathematics Olympiad, the new series of models correctly solved 83% of problems.

To begin with, thinking “like a human” is already a subjective aspect. When it touches upon “no right or wrong answer”, which “side” would the program take when the question is regarding medical technologies / approaches?

The advancement of OpenAI with strong emphasis of human training is stressing more caution than assurance, if anyone may speculate. The fact this model is actively trained in real-time by users, simulatanously by scientists might pose more questions than answers.

Typically, when cancer tumours are in complicated areas, patients are often at high risk of death during surgery, even in advanced nations. In this case, the large tumour was found to be in the patient’s pelvic floor.

Vietnam encounters only between five and ten similar cases each year — accounting for 5% of bone cancer cases. The patient suffered numbness in the pelvic area, limiting his movement and gait. Several consultations with doctors concluded with prognosis of mild soft tissue injuries incurred from playing sports, despite the huge protrusion.

Vinmec’s medical experts realised the cancerous tumour is supplied by a large and complex vascular system, resulting in possible loss of up to 10 litres of blood during surgery. On the other hand, the tumour’s compression on vital organs such as the digestive system, urinary system, spine, pelvis, and blood vessels was a challenge to approach.

In a case of hemorrhage, it would lead to an uncontrollable situation without clearly revealing the tumour and related parts. However, without surgery, the patient would face the risk of left leg muscle atrophy, and eventually death.

Additive Manufacturing — Prelude To Procedure

The technology greatly help the medical team plan the procedure by printing the tumour, consequently, providing a visual and accurate assessment of shape, volume, and correlation with vital organs. Based on that, doctors could plan the operative approach and minimise complications.

Prior to the surgery, the radiologists embolised large blood vessels of the tumor to minimise blood loss during surgery. The next day, cardiologists, gastroenterologists, and urologists participated in the initial phase of surgery. Cardiologists exposed and controlled the iliac artery, and may perform ligation when bleeding is severe. The urologist then released the bladder and ureters from the tumor, and the gastroenterologist performed a dissection to protect the digestive tract. 

Orthopedic experts removed the tumour through two incisions in the abdomen and behind the thigh. During the major surgery, the team of anesthesiologists continuously monitored and adjusted to maintain a stable state and minimise post-operative complications simultaneously. The team that participated in this major procedure comprised over 30 medical professionals. The process took 8 hours.

The patient resumed normal activities after three days and was discharged a week after. However, he was advised to wait for the pathology results is necessary to consider radiotherapy, but it is only an additional method. In this case, successful surgery is the best treatment for cancer.

Currently, there are few centers in the world applying 3D printing technology to disease models for preoperative planning of complex cases. Vinmec is the first and only unit to carry this technology in Vietnam. Presently, 100% of bone, joint, and cancer surgeries at Vinmec are performed in the same process: a virtual surgery (on the software), an experimental surgery (on the model), and then an actual surgery (on the patient).

Prof. Ph.D. Dr. Tran Trung Dung – Director of the Center for  Orthopedics and Sports Medicine, Vinmec International Hospital

Prof. Ph.D. Dr. Tran Trung Dung – Director of the Center for Orthopedics and Sports Medicine, Vinmec International Hospital said: “The giant bone tumour in the pelvis (like a pregnant woman) compressed the left sciatic nerve, causing numbness and left leg atrophy. Untimely treatment leads to loss of function in the left leg, and is even life-threatening.

”Due to the increased size of the tumour, it would compress and cause blockage in the digestive or urinary system. Therefore, it is necessary to remove early to help restore limb function and avoid distant complications of the digestive and urinary systems.”
