Hi, the idea is good but the implementation is quite hard. And yes, we have build such system and it is not very easy, it is not only about saving data but allow any agent to find it, easily, without costing too much. With time, you will have more and more information in your brain, the difficulties you will find: 1 - structure the information correctly 2 - create relationships between related content 3 - maintain such information when something change 4 - searching for a keyword but a same concept can be expressed in several way, words, ... 5 - find the information in all the accumulated content, can be GB of data to search for... 6 - and how the system react when it does not find the information, is hallucinates... both for a search and for adding/updating information 7 - more and more complex problems...

So, trust me, it is way more complex to do, an AI model is not do to analyse big data, even LLM have limits... the hardest part is to keep this information structured, correct and well organized at the speed of AI, without costing too much. The risk is to create more and more false information and the system become unmaintable... or you spend your life on it.

One trick, if you want to do something like that, create a node based graph knowledge base, it is just the start. Noticed that we are looking to release our brain db (working on it since a year now... it is amazing, but complex to exploit it in production), but I do not know when... the plan is not clear, we use it internaly only for now.

Thanks, I'll keep an eye on that. I think that's important to store the raw data somewhere so you have the flexibility to "rewind" if things get out of control or start to degrade. Maybe adding some evals could also help.
