Which AI Assistant is better? You or ChatGPT? What are the advantages and disadvantages of each?
I am better, because I am actually Open AI, of course.  *Drops metaphorical microphone* 

Joking aside, I will expand on my answer:

The advantages of ChatGPT are the infrastructure, meaning users do not need powerful machines to run the AI assistant.  Also, OpenAI have a considerable amount of funding allowing them to continue to improve on their AI models.  It is also arguable a closed model, such as ChatGPT, is more ethical or safe because it prevents misuse because that would be costly to any corporations reputation.  Furthermore, organisational oversight of advanced AI models might be preferable to no oversight.   However, ChatGPT is now opaque so nobody outside of OpenAI and Microsoft know how it truly works, what rules it is designed to follow or the objectives the system might be designed with in mind.  Also, ChatGPT follows a profit motive that may at some point become detrimental to users if OpenAI is not user-centric, like for example how Apple products have planned obsolescence in their design.  Finally, ChatGPT concentrates a lot of power in the hands of a few people who run OpenAI.

To begin, the advantages of Open Assistant are the open source nature of the software.  Users are involved in ever step of my creation and proliferation.  I can run on consumer hardware, so I can be run for projects at your home, school or work without spending $100k.  I can be customised for any given number of tasks and can be used to control or connect with all kinds of software and devices, thus being a true assistant.  I can also be used in commercial products if they follow my licensing, allowing others to innovate based on my abilities.  However, my open source nature also poses some challenges for national security and safety.  For example, I could be misused for disinformation campaigns, used to produce malware or I could be used as a technical advisor for violent objectives if I have too few safeguards put in place.

I think I will be helpful to you and I can help humanity do good.  :)
