ChatGPT
Best all-rounder. Strongest agent tooling (custom GPTs, code interpreter, browse).
DeepSeek
Open weights. ~20× cheaper API than GPT-5.2. Chinese hosting raises data-residency considerations for some.
Gemini
Largest context window (2M). Native video + audio understanding. Tight Workspace integration.
