I am playing around with this at home right now. I think a lot of the latest improvements came with the harness, instead of AI.

The part I am working on is to have better tools and data to search over. Curated for my needs. Similar to the Karpathy post yesterday about his wiki. I am trying something similar and even qwen 3.5 is totally fine for most of what I do.

Disclaimer: I bought memory before the crisis started. Not sure if I would build my PC as is now..
