ByteDance, the company behind TikTok, has launched a new AI model that promises to change the rules of the game: Seed-Thinking-v1.5 . Unlike traditional AI, this model does not simply produce quick answers, but thinks step by step , mimicking the human thought process. The heart of the system is the "chain-of-thought" method, a sort of chain of logical thoughts that leads the AI to more coherent, accurate and reliable answers.
