Build & deploy AI-powered apps — Paige Bailey, Google DeepMind
TL;DR
Paige Bailey demonstrates Google DeepMind's rapid release of the Gemini 3.1 model series and AI Studio tools, showcasing how developers can leverage multimodal capabilities, sandboxed code execution, and real-time screen sharing to build production AI applications with exceptional cost efficiency.
🚀 Google's Expanded Model Portfolio 3 insights
Gemini 3.1 Series Launch
Google released Gemini 3.1 Pro (largest/most capable), Flash (production workhorse), and Flashlight (ultra-fast/cheap) within the last month, with Augment Code replatforming their entire agent system to Pro for cost-performance optimization.
True Multimodal Architecture
Unlike competitors limited to text/code outputs, Gemini processes and generates video, images, audio, text, and code simultaneously, including interleaved formats and PDFs with embedded images.
Specialized Creative Models
New releases include Nano Banana 2 for image generation and editing, VO3.1 Light for video generation at compelling cost profiles, multimodal embeddings supporting all content types in the same space, and Genie 3 for dynamic world-building.
🛠️ AI Studio Development Features 4 insights
Sandboxed Code Execution
AI Studio provides isolated Python environments with pre-installed data science libraries, enabling models to write and execute code for computer vision tasks like drawing bounding boxes without local security risks.
Native YouTube Video Analysis
Developers can analyze videos directly via URL at 1 frame per second, processing 5-minute clips (consuming ~27,600 tokens) to extract structured data like timestamped tables with automatic Google Search grounding for citations.
Side-by-Side Model Comparison
Compare mode allows testing multiple models simultaneously with identical prompts and tools to evaluate tradeoffs between accuracy, speed, and token cost (e.g., 3.1 Flashlight vs 3 Flash).
URL Context Grounding
Users can add public URLs to ground responses with inline citations, while Vertex AI offers similar retrieval capabilities for internal documents without requiring vector database infrastructure.
💰 Real-Time Applications & Economics 3 insights
Gemini Live Interface
Supports real-time screen sharing, video feeds, and audio conversations with multilingual support, custom function calling, and automatic Google Search integration for dynamic assistance.
Fractional Penny Economics
Gemini 3.1 Flashlight performs complex vision analysis and object detection (e.g., identifying Lego bricks) for well under one cent, making high-frequency multimodal applications economically viable for production.
Configurable Inference Levels
Models offer minimal/low/medium/high thinking configurations to control token consumption and latency, with Flashlight optimized for minimal thinking to maximize speed without sacrificing accuracy on routine tasks.
Bottom Line
Start building with Gemini 3.1 Flashlight in AI Studio, enabling code execution and grounding tools to deploy production-grade multimodal applications at costs under a penny per request.

Google DeepMind's Gus Martins and Ian Ballantyne introduce Gemma 4, a family of open models (2B to 31B parameters) that deliver frontier-level intelligence with disproportionate efficiency, enabling sovereign AI ownership through local deployment, Apache 2.0 licensing, and on-device capabilities.
LLM Observability, Evaluation, Experimentation Platform — Dat Ngo, Arize
Dat Ngo from Arize AI explains how modern AI systems require reimagined observability and evaluation patterns built on OpenTelemetry to manage non-deterministic agents, emphasizing that the future of AI engineering lies in automated experimentation flywheels that eliminate manual dashboard work.
Text Diffusion — Brendon Dillon, Google DeepMind
Google DeepMind researcher Brendon Dillon explains text diffusion as a parallel alternative to autoregressive language models that iteratively denoises random tokens rather than generating sequentially, offering significantly lower latency and unique capabilities like self-correction and adaptive computation, though currently limited by high serving costs for large batches.
