Google's Gemini Pro lineup has seen no new flagship release since Gemini 3.1 Pro in February 2026, with the announced Gemini 3.5 Pro still unreleased after repeated delays and recent reports that it has been canceled. Trader attention has shifted to the Gemini 4 series, where Gemini 4 Argon became generally available in mid-October 2026 and Gemini 4 Carbon entered limited preview on October 28 for cybersecurity and long-horizon coding tasks. Rapid iteration on Flash variants, agentic capabilities, and multimodal tools continues amid competition from OpenAI and Anthropic, while DeepMind focuses on completing Gemini 4 pre-training and rolling out more efficient models. Key near-term catalysts include any public Gemini 4 Pro variant or confirmed 2027 roadmap updates.
