Google’s Gemini 3 Pro preview has surfaced in VertexAI code, suggesting a launch in November. The label “11-2025” implies that select users could access it soon, with a wider rollout expected in December. This aligns with previous A-B testing activities in AI Studio, where Google has been benchmarking the model. The Gemini 3 Pro is anticipated to offer a 1 million token context window, consistent with earlier Gemini versions, making it a significant tool for developers and enterprise teams already utilizing VertexAI. The implications of Gemini 3 Pro are substantial. With a confirmed 1 million token context window, it enhances the capacity for managing large documents and data streams, which is crucial for AI researchers and businesses that require robust context-aware capabilities. Furthermore, this model will integrate into Google’s API services and product suite, expanding its usability across various applications. The article also hints at a connection between Gemini 3 Pro and Google’s upcoming image generation model, Nano Banana 2. There’s speculation that Nano Banana 2 might use Gemini 3 Pro as part of its infrastructure, or they could be launched together as part of a broader update. Unreleased code has revealed these developments, indicating that announcements from Google are likely imminent. Overall, these advancements mark a significant step in Google’s AI strategy.
