Claude, ChatGPT, and Gemini were built with fundamentally different training philosophies, and those differences change how you should actually use them.

The Training Differences

ChatGPT was trained using RLHF. It optimizes for responses that feel satisfying. The result: expansive, agreeable, thorough answers. Strong image/video generation with DALL-E and Sora.

Claude was trained using Constitutional AI, with explicit principles like "be honest." The result: more likely to push back, flag problems in your thinking, and ask clarifying questions. Best-in-class writing and complex instruction following.

Gemini was built for multimodal from the ground up. Native understanding of text, images, video, and audio. Massive context windows (1M+ tokens). Deep Google Search integration for real-time information.
