How are you looking to augment Generative AI with inner-source and internal AI systems?

I’ve been spending a lot of time recently thinking about how we look to build internal AIs. Although ChatGPT (and similar) are all great tools for coding (code generation/completion and explanation) there is a massive amount of internal code within companies that are not part of the AI system. Aligned with that are the cultural aspects of what has been internally created, the inner source and property that companies create.

Do we expect that we will all run/access multiple AIs over time. Competing for the best, or will it become a monopoly (similar to the search monopoly that Google has had over the last 10 years).
