I went off track answering you before. I was still in the mindset of music AI’s.

Your question was more generalized towards legal AI’s (legal as in law).

Answer to your question is: we must first ask what the purpose of the AI is, and what type of AI it is.

An AI that would solve the problem you mention would most likely be a classifier of some sort.

It would read cases, and depending on the input data it would generate a binary answer: guilty or not guilty.

That’s the simplest form.

A more complex version could maybe output a range of values, to more precisely dictate the sentence, such as: Social service 6 months, or prison 3 monrhs, or jail 2 years 4months 2 days 13 hours etc…

An even more complex model could maybe work as a Large Language Model much like OpenAI chatGPT or Google Lamda 2 which could output detailed information about the evidence presented, the defense presented, the circumstances, and the final decision, such as:

The defendant is found not guilty for murder because the victim had multiple times triggered psychological attacks by definition of the following medical research papers (see references) which caused defendant to enter a neuropsychotic mental state where the only perceived impression of the situation was death of defendant, which in such situation only fight would be the only solution to flight, given the layout of the room presented in the photos provided by law enforcement and the relative position between defendant and victim.

More so…

You get the idea.

Multiple models could be used to perform different tasks, such as describing by text, or visualizing by image and video, and speaking by audio.
