The energy was palpable at Google I/O, with Google DeepMind and Google for Developers leading the charge. The core message? Getting Google’s “best models into your hands and our products, ASAP”. The focus was heavily on the rapid progress of their models and how they are enabling a new era of AI-powered experiences across the board. It was clear that Google is pushing the frontiers of AI, integrating it deeply into their products and making it accessible to developers.
The Brains Behind the Magic: Gemini and Gemma Updates
At the heart of many announcements were the updates to Google’s foundational AI models: Gemini and Gemma.
•
Gemini 2.5 Pro: Already a powerhouse, the updated 2.5 Pro is Google’s “most performance and powerful model”. It’s designed for “highly complex task that require a lot of deep reasoning”. and has proven to be a “standout use case” for coding. It’s leading across major benchmarks, including sweeping the LMArena leaderboard and being number 1 in the WebDev arena. For those pushing the boundaries, a new advanced mode called Deep Think is being rolled out to trusted testers, allowing the model to “think through various possible answers to a problem before giving you the best answer,” pushing performance to its limits with cutting-edge reasoning techniques.
•
Gemini 2.5 Flash: Described as Google’s “most efficient workhorse model,” the updated 2.5 Flash offers “one of the best price performance ratio in the market today”. It’s faster and cheaper than Pro, suitable for “high volume tasks” like summarization. The new Flash is improved “across key benchmarks for reasoning, code, and long context”, coming in second only to 2.5 Pro on the LMArena leaderboard. Developers will soon have the ability to set thinking budgets for Flash, controlling cost and latency.
•
Other Gemini Models: The lineup also includes 2.0 Flash-Lite (small, fast, cheap) and models for on-device processing (Gemini Nano) and embedding. Older versions like Gemini 2.0 are still available, but the push is towards experimenting with the newer, better-performing 2.5 models.
•
Gemma 3: Google’s open family of models, Gemma, saw a significant update with Gemma 365. Based on Gemini technologies, Gemma 3 is multimodal, capable of receiving and having conversations about images and video. It’s available in multiple sizes (4B, 12B, 27B), offering a range of performance and hardware requirements. A key aspect is its accessibility – Gemma is designed to be run locally on your own laptop or phone, integrated with Open Source tools, and fine-tuned for specific use cases or domains. New variants like MedGemma (for the health industry, including medical images and text), SignGemma (expanding to sign language understanding), and ShieldGemma (for image safety classification) were also highlighted.
More Than Just Text: Rich Multimodal and Generative Capabilities
The updates didn’t stop at core models. Google announced significant advancements in multimodal understanding and content generation.
•
Audio Magic: Gemini TTS (text-to-speech) was launched, capable of generating “high-quality audio” with customizable “motions,” “multiple voices,” different “languages,” and even “mood speaker interactions” for podcast-like performance. For real-time interactions, the Gemini Live API now offers native audio output models, providing more natural and compelling voices with seamless language switching.
•
Image Generation & Editing: The latest image generation model, Imagen 4, is coming to the Gemini app, offering “richer” images with “more nuanced colors and fine-grained details”. Crucially, it’s significantly better at text and typography, even making creative choices in font and layout. You can also edit images generated with Imagen 4 directly in the app. A super-fast variant is also available, generating images 10 times faster than the previous model for rapid iteration. The Gemini Image Out variant also allows for image generation and editing.
•
Video Generation & Sound: A major leap was the announcement of Veo 3, Google’s new state-of-the-art video model. Veo 3 not only offers improved visual quality and stronger understanding of physics but also comes with native audio generation, meaning it can generate “sound effects, background sounds, and dialogue” directly in the video. To help creators leverage these capabilities, a new AI filmmaking tool called Flow was launched today, combining Veo, Imagen, and Gemini to assist with creating cinematic content.
•
Multimodal Understanding: Gemini API now allows uploading various file types (spreadsheet, docs, video, audio) and analyzing media information. New video capabilities include analyzing YouTube links, processing up to 6 hours of video at lower resolution settings, dynamic frame rates, video clipping, and image segmentation. The models can understand complex information and perform reasoning or calculations based on the input.
The Age of Agents: AI Taking Action
A significant theme was the rise of AI agents – systems that combine AI models with tools to take actions on your behalf.
•
Computer Use: Project Mariner, now evolving into Computer Use capabilities, allows AI agents to interact with browsers and other software. It’s gaining multitasking ability (up to 10 simultaneous tasks) and teach and repeat, where you show it a task once, and it learns a plan for similar tasks. This is being rolled out to developers via the Gemini API.
•
Agent Mode in Gemini App: An “experimental version” of Agent Mode is coming soon to subscribers. This mode in the Gemini app uses agents (like Project Mariner) to perform complex tasks like finding apartment listings based on specific criteria, adjusting filters, accessing listing details, and even scheduling tours.
•
Jules, the Coding Agent: A specific agent tailored for developers, Jules, is an “async agentic coding agent” that can “code your AI agents” and handle complex tasks like fixing bugs or updating codebases. It integrates with GitHub and is now in public beta.
Agent Ecosystem: Google is supporting agent frameworks like Google SDK/kit and collaborating with Open Source tools like LangChain. They also support an Agent to Agent protocol and the Model Context Protocol (MCP), making it easier for agents to talk to each other and access other services.
Putting AI to Work: New Tools and Experiences
Beyond the core models and agentic capabilities, Google introduced or updated several tools accessible via the Gemini API:
•
Google AI Studio: This popular web-based tool lets developers “test out the capabilities of API before committing to building applications at scale”. It now includes code generation. It’s described as a “UI and no-code experience” to quickly access features.
•
Search Grounding & URL Context: Tools to bring “fresh information” using Google Search grounding. A new tool called URL context allows extracting “more in-depth content” from a set of URLs (up to 20 links in a prompt) for deep research and analysis, powering features like the Google research Agent.
•
Code Execution & Function Calling: These tools are available via the API for tasks like creating charts or running analysis. Function calling, bread and butter for agentic apps, now supports asynchronous functions, allowing them to run in the background.
•
Structured Outputs: The API now offers more robust and comprehensive “structured outputs functionality,” letting you get responses in JSON schema.
•
Safety & Copyright Filters: Developers have access to a set of configurable filters to make applications safer, with control over threshold settings.
•
SDK Integration: The Gemini API has SDKs for Python, JavaScript, and GO. Notably, the SDK now supports MCP, allowing you to combine MCP clients/servers and Gemini API interactions in the same codebase.
