AI Daily: Google 2025 Year in Review, Major Updates for Kilo & Windsurf, and Year-End Deals

2025 has been a year for the history books in the field of Artificial Intelligence. If 2024 was about laying the foundation for multimodal models, 2025 marks the point where AI truly began to think, act, and explore the world alongside humans.

This post dives into Google’s new annual research report, exploring how Gemini 3 is changing the game. We then discuss Kilo’s new App Builder and how it challenges existing AI code generation tools, as well as the surprises in Windsurf’s Wave 13 update. Plus, the year-end deals you care about most, including offers from Google One, Claude, and Codex.

Google 2025 Year in Review: When AI Truly Starts Thinking and Exploring

Looking back at 2025, the role of artificial intelligence has undergone a fundamental shift. It is no longer just a tool used unilaterally by people, but has transformed into a practical utility capable of proactively assisting in work. Google’s report card for the year is impressive. According to Google’s official 2025 Research Breakthroughs Report, progress this year spans everything from foundational models to scientific discoveries.

Gemini 3 and Model Evolution

The most notable development this year is undoubtedly the continuous evolution of the Gemini series. From Gemini 2.5 early in the year to the debut of Gemini 3 in November, Google has constantly pushed the technological ceiling. Especially Gemini 3 Pro, which not only topped the LMArena leaderboard but also demonstrated amazing reasoning capabilities in challenging tests like Humanity’s Last Exam.

Did you know? It’s not just about higher scores. Gemini 3 Pro set a new record in the mathematics field, achieving a score of 23.4% in the MathArena Apex test. This signifies that AI models are getting closer to human thought patterns when processing mathematics, writing code, and performing complex logical reasoning. And the subsequent release of Gemini 3 Flash in December, with its high cost-performance ratio and low latency, proved that the new generation of Flash models can even outperform the previous generation of Pro models in performance.

AI as a Scientist’s Right Hand

Beyond general-purpose models, Google’s contribution to the scientific field is equally immense. On the fifth anniversary of AlphaFold, the system has solved the protein folding problem that had plagued the scientific community for half a century, with its influence even helping researchers win the Nobel Prize.

Furthermore, Google researcher Michel Devoret and his team were jointly awarded the 2025 Nobel Prize in Physics for their foundational research in quantum computing. These applications prove that AI technology is moving out of the laboratory. Whether it’s hyper-local weather forecasting via the WeatherNext 2 model or early wildfire detection via the FireSat system, AI is tackling the most thorny climate and health issues in the real world.

New Frontiers in Creativity and Robotics

In the software development realm, the launch of Google Antigravity and the asynchronous Coding Agent Jules marks a new era for AI-assisted development. In the physical world, the introduction of Genie 3 has opened up a new battlefield for general world models, allowing robots to more accurately understand and interact with their physical environment.

Kilo App Builder Debuts: Not Just a Toy, A Dev Tool for Serious Projects

There are many tools on the market that claim to “let anyone write code,” such as Lovable or Bolt. They are indeed cool, but for professional developers, when complex modifications or maintenance are needed, the code produced by these tools can sometimes be frustrating.

Bridging the Gap Between “Prototype” and “Product”

Kilo Code has clearly spotted this pain point. Their newly launched App Builder is positioned as “Lovable for serious projects.” Its core philosophy is straightforward: you can still use natural language to describe requirements and watch the application generate and preview in real-time in the browser.

But the biggest difference is that when you are ready for more advanced development, you can seamlessly switch to Kilo Code’s professional environment (supporting VS Code, JetBrains, or CLI). This relies on Orchestrator Mode and Managed Indexing technologies, meaning you don’t need to discard the original prototype and rewrite it, nor will you lose context by switching tools.

A True “Vibe Coding” Experience

The “Kilo Speed” emphasized by Kilo is about eliminating valuable friction. No need to set up tedious environments, no need to handle deployment configurations, just focus on your ideas. And the threshold is extremely low; as long as your Kilo account has a balance of $1 and a payment history, you can start using it. For engineers who are fed up with the limitations of No-code tools but want to speed up development, this is definitely an attractive option.

Windsurf Wave 13 Update: Parallel Agents and Free SWE-1.5 Model

Competition in development tools has reached a fever pitch at the end of the year. The Cognition team released the Windsurf Wave 13 update, codenamed “Merry Shipmas,” full of festive atmosphere.

The Ultimate in Multitasking: Cascade Panes

This update introduces multiple Cascade panes and tab features. What’s the benefit? Imagine you can run multiple Agent sessions simultaneously and display them side-by-side. You can have one Agent write tests on one side, while another Agent refactors code on the other, monitoring their progress in the same window. This makes Windsurf no longer just an editor, but more like a multitasking command center.

Git Worktrees Solves Conflicts

Another feature that will make developers smile is support for Git Worktrees. This saves you from frequently switching directories or stashing changes just to switch branches. You can open multiple Cascade sessions in the same repository to handle different branches without interfering with each other.

No More Stuck Interactive Terminals

Wave 13 also introduces the Beta version of Cascade Dedicated Terminal. It switches to a more stable zsh environment, and most importantly, supports “interactive commands.” This means that when your script requires user input (such as confirming file overwrites or entering configuration values), the Agent won’t get stuck, making the automation process smoother.

Shipmas Gift: Free SWE-1.5

The Windsurf team also sent a big gift: for the next three months, all users can use the new SWE-1.5 model variant (codenamed Penguin Alpha) for free. It will directly replace SWE-1 as the default model. Although its speed is standard (the high-speed version of the non-paid version), it retains full intelligence and coding capabilities. In addition, the new “Context Window Indicator” allows you to keep track of Token usage at any time, preventing the model from “getting dumb.”

Year-End Deals Special: Google One Half Price, Double Usage for Claude & Codex
