## Our verdict

Both ship 1M-token context windows, but with very different tradeoffs: Gemini 3 Pro adds native video and tighter Google Cloud integration; DeepSeek V4 is open-weights at half the price and stronger on STEM reasoning. Pick Gemini for video / multimodal pipelines on GCP; pick V4 for self-hosted long-context analysis where vendor independence matters.
