Core AI Models & Capabilities:
Imagen 4 Launch: Google’s newest and most capable image generation model, offering higher quality, photorealism, artistic detail, and conversational image editing, setting new benchmarks for visual content creation.
Gemini 2.5 Model Enrichments: The expanded Gemini 2.5 Ecosystem (Pro, Flash, Flash-Lite) provides diverse, cost-effective options with advanced “thinking capability.” Flash-Lite, in particular, offers highly accessible pricing at just $0.10 per 1M tokens for input, democratizing powerful AI.
Gemma 3 Model Enrichments: This new open-model family brings enhanced multimodal input (image, audio, text) and new tools like RAG, grounding, and function calling. Gemma 3.0-Nano delivers efficient, on-device multimodal AI, ensuring faster, more private, and offline experiences on mobile and wearables.
Gemini Text-to-Speech & Native Audio Models: Enables high-quality audio generation for various uses (podcasts, teaching) and real-time, interruptible AI conversations with controllable voice, tone, and style, delivering natural-sounding voices and seamless multilinguality.
Multimodal Understanding & Long Context: Gemini’s expanded capabilities include native processing of web page URLs (URL context), YouTube link support, dynamic video frame rates, video clipping, and image segmentation. Models now feature significantly longer context windows (1M tokens for Pro and Flash).
