oh yeah i said i can't remember opus lying but it does sandbag abilities a bit sometimes for me too in certain planning contexts. but that usually feels on the boundary of untruth and just situationally bad calibration / self knowledge. ("this will take three weeks" no we're going to finish it tonight, or eg i saw a screenshot where opus claimed porting a project to jquery was "impossible" when really it would just be a massive pain, unpleasant, and in human developer time would take months.)
