Questions
Where do these facts come from?
From the maker's own announcement, docs or price list, linked and dated on the page. A point from anyone else says whose page it is. What a model costs in llmwise comes from llmwise's plans, so it always matches the pricing page.
Is every model in the news in llmwise?
No. Each page names the llmwise models it's about; one that isn't in llmwise yet says so, and names the model to use until it is.
