i know i've been griping about a couple SOL things but overall the GPT 5.6 models are *incredible* - here's my highlights Sol - doesn't talk like a robot anymore - super well done and impressive. not quite fable-level but soooo much better than 5.5 Terra - truly a sonnet-class model, great for research subagents, and really strong for general knowledge work - nice! Sol - still not great at UI - much better, but not reaching the opus-level of "yolo in a prompt and get something beautiful without even trying" The other thing to watch out for - these models LOVE subagents and skills - very well tuned to use them, which means we had to refine a lot of things in our general workflow 1) many skills and prompts steered pretty hard to subagents "use them", "use them in parallel", etc - this is no longer necessary 2) many skills advertised hard in description field - "pick me", "you MUST use this skill whenever ..." - that is complete overkill now 3) in fact we're disabling model invocation on a bunch of skills cause I had never need a model reach for them before and now its regularly invoking skills/commands I forgot even existed 4) i had built an intuition around typing "use a subagent"-ish things when prompting. no longer necessary. instead i am building intuition around "no subagents" and i send this probably 1 in 4 prompts to Sol all around great release - reminder that ever new generation of models means you should review and potential throw out a bunch of your skills/prompts/instructions that are no longer necessary more updates as we go, what did I miss?
