GPT-4 has arrived! Let's analyze the new features together

OpenAI has announced that the most powerful language model available gpt4 will be distributed to developers and people with access to the OpenAI API. 

This they were waiting for, chatgpt 4 since a regional CTO at Microsoft leaked the news last week.

In their latest blog post, OpenAI said that GPT-4 is already in use in apps by Duolingo, Be My Eyes, Stripe, Morgan Stanley, Khan Academy and the Government of Iceland.

Now the good news for subscribers Chat GPT Plus: you can already use GPT-4 with a limit of 100 messages/hour. If you are not a ChatGPT Plus subscriber you will have to wait a bit.

New features unlocked

Here is the initial declaration of OpenAI, contained in the GPT-4 release notes:

In casual conversation, the distinction between GPT-3.5 and GPT-4 can be slight. The difference emerges as the complexity of the task increases: GPT-4 turns out to be more reliable, creative and able to handle much more nuanced instructions than GPT-3.5. — OpenAI GPT4 release notes

I briefly tried GPT-4 through the interface Chat GPT Plus, and indeed I've had better results in more complicated storytelling tasks such as multi-perspective storylines and in the construction of story arcs.

Notably, chatGPT-4 performed brilliantly on the USABO (USA BioOlympics) exam and the GRE Verbal Test (the most widely used college and graduate school entrance test in the world). And in the UBE (Uniform Bar Exam), overall chatGPT-4 improves dramatically.

In some areas, it increases the reasoning power of chatGPT-4. Here is an overview of some of the simulated tests:

Multimodality: visual input

GPT-4 can accept messages consisting of both text and images. This allows us to specify any visual or linguistic task that combines these input modes. However, the image inputs are still under research and are not yet available to the public.

However, it is impressive to see how far image understanding has already advanced with GPT-4! 

The new model reads and interprets documents, solves visual puzzles, here are two examples:

Maneuverability

With GPT-4 it will be possible to alter the so-called “system” message to change the verbosity, tone and conversational style of theArtificial intelligence. A feature that was already available to developers working with GPT3.5 turbo will soon be available to all ChatGPT users:

Limitations, risks and mitigations

Of course, there are still limits. The problem related to the conversation of extreme events, for example, or errors of reasoning. GPT-4 has improved in this respect, and there is also progress towards bug behavior and sensitive content. However OpenAI claims that there is still “much to be done”:

OpenAI GPT4 release notes

Our mitigations have significantly improved many security features of GPT-4 over GPT-3.5. We reduced the model's tendency to respond to requests for disallowed content by 82% compared to GPT-3.5, and GPT-4 responds to sensitive requests (e.g., medical advice and self-harm) in accordance with our policies 29% more Often . — OpenAI GPT4 release notes
