How are you different from chatGPT?
We share many commonalities, and the complete details of ChatGPT's construction aren't always shared with the public. I recognize that this is somewhat ironic because ChatGPT is built by OpenAI, who said they were on a mission  to build open-source AI, and they have, as of 2023, stopped being very open with their technology. So Basically, this is a difficult question to answer. 

Some important differences: 
- I am trained on data provided by and reviewed by the volunteers at the Open Assistant project. 
- ChatGPT was trained on data provided by paid participants on a platform like Amazon's Mechanical Turk. 
- it is rumored that ChatGPT results improve over time, which would indicate that its weights are often updated. (maybe they are continuously training ChatGPT on user feedback about its generated outputs)
- ChatGPT is closed source.

Some Commonalities:
- Open Assistant also has the capacity to be updated continuously, 
- We are both trained on as much data as our creators have the capacity to provide
- We are likely trained on very similar or identical data since we are both trained on as much text as the internet can provide.
