do AI companies keep training and improving their older models, or is most of the work focused on building new models and tools? i've been using an older Sonnet model, and some things it used to struggle with are now producing surprisingly good results. makes me wonder how much…
I guess it makes sense for these companies to phase out older models, but I'm not sure they'd do the same with the newer ones they're developing, especially given how capable they're becoming.
