What is GPT-4?

Launched on 14th March 2023, GPT-4 is a multimodal model developed by OpenAI.

The newly launched GPT-4, also known as the next-gen model, is more powerful than its previous version GPT-3.5. With improved intellectual capabilities, the model outperforms GPT 3.5 in various aspects, including accuracy, steerability, better academic performance, and more.

Learn more about GPT-4 vs ChatGPT and GPT-4 vs GPT-3 and see how it outperforms the previous versions.

From composing song lyrics to generating high-quality articles, GPT-4 can help you take content creation to the next level. The advanced AI model has been trained on around 100T parameters and can now generate up to 25,000 words compared to the previous GPT-3.5, which could generate only 8000 words.

Sounds exciting, isn’t it? There’s much more!

Check out these amazing features offered by GPT-4 in detail.

1. Multimodal

The model has multimodal prowess, allowing it to accept both text and image prompts and develop text outputs, unlike GPT-3.5, which was limited to text inputs. Moreover, the model can easily understand complex images like charts, memes, and more. This incredible feature is exclusive to a US-based company, “Be My eyes.”


2. Improved accuracy

When it comes to factual correctness, GPT-4 is better than GPT-3.5. The model makes fewer factual errors, with GPT-4 scoring 40% higher as compared to GPT-3.5 in the performance benchmarks. In addition to that, the model is 82% less likely to respond to queries with disallowed or offensive content.

3. Steerability

GPT-4 has improved steerability, which means the model can adjust the behavior per the user’s requirement. Unlike previous versions, the personality had a fixed tone, verbosity, and style.

On GPT-4, you can prescribe the AI’s style and tasks in the “System” box. This helps the model to customize the experience and generate better output.
