The week(s) after re:invent are typically the time, where a pile of very good content videos pile up at my end and I have both a hard and fun time to get through this.

After all it’s a level 200 session - should be able to follow it during a casual workout, right?

โค๏ธ Great talk by Cal Rueb - I loved not just he content but his casual story telling style. After all learning from real experience is the best - and certainly Cal’s experience from building Claude Code are a good place to start from .

๐Ÿ’ฐ Quite some stuff in the tall will get to it some time. Loved e.g. the statement that absolute cost per token might not be the only dimension to look at but also factor in token efficiency per use case - how many billed tokens a model actually spends to get your task done, so a pricier-per-token model can come out cheaper per solved task.

๐Ÿš๏ธ @Cal Rueb, the slide on the first screenshot broke me kind of. I was sure that this must have been Claude, but then you mentioned that is is not. I know get it, but took me a long time that things with timestamp don’t need to be ordered by timestamp on the slide.

@Cal Rueb: What happened to the Claude Code project building entire time at re:invent based on visitors GitHub issue? Frankenstein or the next big thing?!
