Inside a Virtual Hospital Where AI Doctors Are Trained

Researchers from the Institute for AI Research (AIR) at Tsinghua University (China) have created a virtual hospital simulation to train AI doctors.

Welcome to Agent Hospital, where AI agents roleplay as doctors, nurses, and patients, simulating the entire hospital experience from disease onset to post-hospital follow-up.

The goal? To create AI doctors that can handle tens of thousands of cases in a matter of days, a feat that would take human doctors years to achieve.

How it works:

  • AI agents are assigned roles such as doctors, radiologists, nurses, receptionists…etc.

  • Patient agents move through the simulated hospital process, just like real patients.

  • AI doctors treat a potentially infinite number of patients, gaining experience rapidly.

The researchers believe this novel training strategy could make medical AI agents smarter and more efficient than traditional methods like pre-training and fine-tuning.

Looking in the Future

In a visionary future, every physical hospital could be accompanied by a parallel digital twin – a hospital simulation that mirrors its real-world counterpart. This virtual hospital would be equipped with access to the same wealth of information available to human doctors, including patient histories, test results, and real-time monitoring data.

Imagine a scenario where a human doctor, at any given moment, requires a second opinion. The human doctor could engage in a discussion with its virtual agent about the patient in question, seeking guidance on the next steps in treatment, weighing the advantages and disadvantages of various approaches, and more.

This kind of context-aware support, available 24/7, could pave the way for a world where AI and doctors work closely together to provide better patient care.


Learn How AI Impacts Strategy with MIT

As AI technology continues to advance, businesses are facing new challenges and opportunities across the board. Stay ahead of the curve by understanding how AI can impact your business strategy.

ChatGPT Gets a Major Upgrade with GPT-4o

OpenAI has released a significant update to ChatGPT, introducing the new GPT-4o model. This multimodal AI can understand text, images, video, and audio, offering enhanced reasoning, processing, and natural language capabilities.

What’s New?

  • GPT-4o is now available for free ChatGPT users.

  • Multimodal capabilities spanning visual, audio, and text interaction, including real-time use with phone cameras.

  • Human-like conversation abilities, allowing users to interrupt the AI assistant during interactions.

  • Operates across 50 languages, now enabling real-time translation.

  • Desktop app for Mac users (Windows app is coming later this year)

How to Access GPT-4o:

  1. Sign in to your ChatGPT account or create a new one.

  2. Check the model drop-down menu for GPT-4o. If it's not listed, you don't have access yet (the rollout is gradual, with access being granted in batches).

  3. Start chatting with GPT-4o, keeping in mind the rate limits for free users.

  4. You can change the AI model during a conversation by selecting the sparkle icon

  5. Upload files (images, videos, PDFs) for analysis and ask questions about the content.


AI in Radiology: A Boon or Bane for Radiographers?

A recent survey of nearly 400 radiographers, published in BMC Medical Ethics, reveals mixed feelings about the integration of AI in radiology. While AI offers potential benefits such as improved diagnostic accuracy and workflow efficiency, radiographers are apprehensive about the ethical challenges it presents.

Key Concerns:

  • Transparency and justification of AI decision-making (40% of respondents)

  • Ethical dilemmas, including bias, data privacy, and ownership (44%)

  • Potential job displacement and the need for further training

The study's author, Faten Mane Aldhafeeri, suggests implementing ongoing professional development programs specific to AI in radiology. This would empower radiographers to navigate ethical challenges and contribute to the responsible use of AI in healthcare.

AI Coaches Fall Flat for Weight Loss, Study Finds

A new Northwestern Medicine study reveals that technology alone is not enough to replace human coaches in obesity treatment. The study compared two approaches: one using only technology and the other combining technology with human coaching.

Key Findings:

  • Participants who initially received only technology had worse weight loss outcomes compared to those who had a human coach from the start.

  • Even after intensifying treatment for those with suboptimal weight loss, the disadvantage persisted for six months.

  • 25% of participants using only technology achieved clinically meaningful weight loss (5% of body weight) after six months without treatment augmentation.


While the need for low-cost, technology-driven obesity treatments is urgent, current AI is not advanced enough to replace human coaches entirely. Researchers are working to understand what makes human coaches successful and how AI can better imitate their emotional tone and context awareness.

The study highlights the importance of matching treatment type and intensity to individual needs and preferences to effectively manage the obesity epidemic.
