    Phenomenal model, not sure what they did, but I have been able to do so much with my $20 plan!

      If enough people keep saying it I'm sure they will nerf it

      I think what makes it great is that they trained it to write harnesses for the code it writes, so it can test stuff even if the supplied code is not complete.

        the open weight models I've been using have been doing that for months, not sure it's a new pattern in the opus 5.5, or maybe they distilled it back? :x

      A significant part of it is that with Opus 5.5, cache reads are priced at 5% of inputs, instead of 10% for previous models.
