Gemini 3.0 (Base Model)
by Google / DeepMind
Google’s foundational model with three core architectural upgrades: deeper reasoning, stronger multimodality, and 1M-token context. Foundation for Pro, Flash, Ultra, and Nano variants.
Overview
Gemini 3.0 is the foundational architecture powering Google’s Gemini 3 family. Rather than a single model, it comprises a layered constellation of variants optimized for different use cases—from on-device Nano to enterprise Ultra tiers.
Core Architecture
Three Key Upgrades
- Deeper Reasoning: System 2 thinking at speed—plan chains of complex tasks without losing track
- Stronger Multimodality: Native processing of text, images, audio, video, code in single transformer stack
- Expanded Context: 1 million-token context window with caching capabilities
Native Multimodality
- Unified Architecture: Not separate encoders stitched together
- Genuine Cross-Modal Reasoning: Interpret sketches and generate code, analyze videos and explain science
- Real-Time Audio: Low-latency audio encoder and Live API for natural speech-to-speech interaction
- Document Intelligence: Processes PDFs as visual and textual objects simultaneously
- Video Understanding: High-eighties on Video MMMU, low-eighties on MMMU Pro
