Gemini 3 Pro Preview (low) is a multimodal large language model developed by Google, released on November 18, 2025, as part of the Gemini 3 series. It is designed to process and reason across text, images, audio, video, and documents within a 1-million-token context window. The "low" designation refers to a configuration optimized for efficiency and cost, providing a balance between reasoning depth and latency compared to higher-intensity reasoning modes. The model features "thinking levels" for adjustable reasoning intensity, "thought signatures" for increased logic transparency, and "vibe coding" for agentic software development and planning tasks. It is utilized in high-volume production environments and has a training knowledge cutoff of January 2025.
