Google’s Most Powerful AI Model Yet
Google launched Gemini 3.1 Ultra in June 2026 — its most significant model release of the year. Featuring a massive 2-million token context window, Gemini 3.1 Ultra works natively across text, image, audio, and video simultaneously without any transcription intermediaries. Unlike previous versions, 3.1 was designed from the ground up to reason across all modalities at once.
What’s New in Gemini 3.1 Ultra
- 2M token context window — the largest of any frontier model, enabling analysis of entire codebases, books, or video archives in a single prompt.
- Native multimodal reasoning — processes text, images, audio, and video simultaneously without separate pipelines.
- Sandboxed Code Execution — the model can write, run, and test code mid-conversation.
- Improved grounding — significantly fewer hallucinations on factual queries.
- Google Workspace deep integration — available inside Docs, Gmail, Sheets, and Slides for AI Pro subscribers.
Gemini 3.5 Flash Also Launched
Gemini 3.5 Flash — a faster, cheaper model — was also released alongside 3.1 Ultra. It targets developers who need fast inference at scale. The free tier of Gemini (gemini.google.com) now uses Gemini 3.5 Flash as the default model.
Imagen 3 Nano and Pro: AI Images from Video
Google’s Imagen 3 Nano and Pro image generation models became widely available in June 2026. These tools use video files as prompts to create context-aware images like thumbnails and infographics automatically. WPP integrated Imagen 3 into its marketing platform for clients like Verizon and L’Oreal, while Shopify deployed it for product photography generation.
Pricing
Gemini 3.1 Ultra is available via Google AI Pro ($19.99/month). The free tier uses Gemini 3.5 Flash with generous daily limits. Students in the UK, Japan, Indonesia, and Brazil get a free upgrade through July 2026.
