Gemini 3 Pro Preview on OpenRouter (openrouter.ai)

Google’s Gemini 3 Pro preview is now available on OpenRouter — a flagship “frontier” model built for high-precision multimodal reasoning across text, image, video, audio and code. The model supports a 1-million-token context window and is tuned for depth and interpretability: it infers user intent with minimal prompting, preserves reasoning details across multi-turn tool calls, and produces direct, insight-focused outputs. Gemini 3 Pro targets advanced development and agentic workflows with robust tool-calling, long-horizon planning stability, and strong zero-shot generation for complex UI, visualization and coding tasks. Technically significant results back the release: Gemini 3 Pro posts leading scores on general and multimodal benchmarks (LMArena, GPQA Diamond, MathArena Apex, MMMU-Pro, Video-MMMU) and shows agentic coding strength on SWE-Bench Verified and Terminal-Bench 2.0. For the AI/ML community this means easier construction of autonomous agents, coding assistants, multimodal analytics systems, and research/education tools that require long-context reasoning, structured long-form synthesis, and multimodal understanding. The preview on OpenRouter gives developers earlier access to a model optimized for high-context, tool-enabled workflows, signaling a practical step toward more capable, interpretable agentic systems in production settings.
