AI right now, T0 is only Claude. DeepSeek is T1, and OPENAI is barely T1. DeepSeek complements Opus 5.5 well in solving algorithmic and logical problems. QWEN, Yuanbao, Doubao, and the like are probably T2. They win on being cheap, abundant, and filling, but they still can't handle advanced problems. As for Grok, let's not even go there. It can handle some simple tasks relying on X, and with the Grok bot, it barely makes T3. But there's way too much political correctness brainwashing going on. Gemini's level? Barely T4. And they have the nerve to charge for this stuff? Google's products are getting worse and worse. Just my personal experience.
