OpenAI Releases ChatGPT 4

OpenAI announced the release of ChatGPT 4, the latest version of its AI engine and a major advance over previous efforts. Neither company will admit this, but Microsoft has allegedly been using an early version of ChatGPT 4 in its controversial Bing chatbot.

“GPT-4 is the latest milestone in OpenAI’s effort in scaling up deep learning,” the firm announced. “GPT-4 is a large multimodal model–it accepts image and text inputs and emits text outputs–that, while less capable than humans in many real-world scenarios, exhibits human-level performance on various professional and academic benchmarks.”

OpenAI provides an interesting example of that proficiency: where GPT3.5–the previous version of this technology–scored in the bottom 10 percent in a simulated bar exam, GPT 4 scores in the top 10 percent. “We’ve spent 6 months iteratively aligning GPT-4 using lessons from our adversarial testing program as well as ChatGPT, resulting in our best-ever results (though far from perfect) on factuality, steerability, and refusing to go outside of guardrails,” the company claims.

No one is talking Bing here, but OpenAI did highlight how its partnership with Microsoft Azure is paying off.

“Over the past two years, we rebuilt our entire deep learning stack and, together with Azure, co-designed a supercomputer from the ground up for our workload,” OpenAI explains. “A year ago, we trained GPT-3.5 as a first ‘test run’ of the system. We found and fixed some bugs and improved our theoretical foundations. As a result, our GPT-4 training run was (for us at least!) unprecedentedly stable, becoming our first large model whose training performance we were able to accurately predict ahead of time. As we continue to focus on reliable scaling, we aim to hone our methodology to help us predict and prepare for future capabilities increasingly far in advance—something we view as critical for safety.”

ChatGPT 4 is now available from the ChatGPT website.
