Dumb question: When your testing "ChatGPT 5.6 Sol" are you testing an actual LLM or some visual pre-processor stack that sits in front of it (along with a maybe a bunch of other such pre-processors) that is bundled into what's call "ChatGPT 5.6 Sol"? I.e. last I checked LLMs had a something like a 30-100K token alphabet to work with and it's hard to imagine how throwing pixels arrays at one directly would work.
