When ChatGPT first appeared in November last year, it was like a light switch being turned on and we all gained access to a new level of artificial intelligence online. We're all still getting used to that, but OpenAI hasn't stood still. ChatGPT uses GPT-3.5, and OpenAI spent the last six months(Opens in a new window) using the lessons it learned from that alongside its adversarial testing program to create GPT-4, which blows GPT-3.5 out of the water. OpenAI says GPT-4 is improved in most areas. It's more creative and collaborative, accepts images as input, and can generate captions, classifications, and analyses from them. The new model can also handle over 25,000 words of text (8x more than ChatGPT) and surpasses ChatGPT in its advanced reasoning capabilities.
