LLM API Price War Halts Abruptly, Signaling a Shift in Technical Roadmaps

Have you ever wondered why major model vendors were frantically cutting prices last year, even giving away free quotas, but suddenly stopped coordinating on price cuts this year? I recently read Musk saying, "Grok 4.5 isn't the strongest large model, but it's worth a try," delivered with a tone as casual as chatting about the weather. Combined with news of SpaceXAI's massive IPO and a report by TMTPost mentioning "global AI giants collectively pivoting," I have a vague feeling that the competitive logic of the large model industry is undergoing fundamental change.
