Direct Answer to the OP's Question
"Have any AI's been able to decode human vision 'thoughts'" ~ Albert (Stack Exchange user, OP)
This is technology that can produce pictures of what the user is thinking about through scanning a brain.
"Is anyone aware where I can find this?" ~ Albert (Stack Exchange user, OP)
Emotiv is the most accessible commercial model (circa. late 2019).
The OP is probably interested in consumer brain–computer interfaces (also known as BCIs). These are varied technologies which range from:--
- Simple "yes-no" brain-interface (e.g. for people in a coma)
- Advanced programs that control video games through thought, such as a high fantasy wizard duel (Do a search about this on YouTube!)
- Technology that can produce pictures of what the user is thinking about through scanning a brain. (This was mentioned by the OP.)
This Wikipedia page, < https://en.wikipedia.org/wiki/Consumer_brain%E2%80%93computer_interfaces >, compares different models of BCIs.
There also some very serious ethical issues regarding being able to "read brains." I mentioned the medical use; and I hope it goes in this direction.
Deep philosophical discussions can be had on whether it is appropriate to read the brain of a supposed criminal. (I would personally say no.)

[I can't comment on the technical details of this. It is outside of my purview. For example, if you need information about the Python-BCI interface, you will need an expert.]
