I am waiting for prices to get down and in the meanwhile I am gathering as much session data from claude/codex as possible so I can then later use them to fine tune open models. I've built my own session parser/archiver for this.
Same. And I built a search tool for that repository of older sessions, so that I can search through those on all my machines. This helps me to be able to pick something up on a machine I did not originally start the convo on.
