Welcome back to our weekly newsletter. I'm seeing vibe coding and agents becoming a tangible reality through CLI interfaces and distributed communication protocols that make them part of our daily workflows. Robots are closer than you might think, and the advertising integration with AI is becoming more sophisticated. If you prefer listen than read, I also had a fascinating discussion with Alessio and Paolo about these trends and more on our "Risorse Artificiali" podcast released yesterday (Italian only) on Youtube and Spotify.
Trend 1: Vibe Coding and Agents
The main news this week is the donation of A2A to the Linux Foundation and the development of the A2A Java SDK. I'm particularly proud that the A2A Java SDK was developed by my team in collaboration with the Quarkus team and Google. We're excited to have developed this SDK to enable collaboration between agents written in different languages, adding Java, the most widely used language in enterprise environments.
The Agent2Agent protocol represents a fundamental shift in how we think about AI systems. The Linux Foundation announced the formation of the Agent2Agent project with Amazon Web Services, Cisco, Google, Microsoft, Salesforce, SAP, and ServiceNow. This coalition of tech giants signals a clear commitment to creating an open, interoperable ecosystem for AI agents. The A2A protocol provides a common language for AI agents to discover each other's capabilities, securely exchange information, and coordinate complex tasks. This isn't just about making agents talk to each other; it's about breaking down the silos that currently limit artificial intelligence's potential.
What makes this particularly significant for Java developers is that we're now truly positioned to build polyglot agent ecosystems. The AI landscape has been fragmented, with Python dominating AI/ML workflows, JavaScript powering web-based agents, and Java serving as the backbone of enterprise backend systems. The A2A Java SDK bridges these worlds, allowing enterprise systems to participate fully in the agent revolution.
Meanwhile, Anthropic's new feature for Claude that allows users to build AI-powered apps directly within the chatbot is a game changer. The ability to write mini-apps in Claude's artifacts, share them (there's already a marketplace!), and potentially modify those shared by other users opens incredible possibilities. This brings conversational interface capabilities for prototyping functional mini-applications that can be reused as is. It unlocks the possibility of creating ephemeral applications that until now were relegated to the technical limitations of office program macros. While conversationally creating a mini-application absolutely doesn't replace professional app development, it will very likely replace many Excel macros 🙂.
I've been testing Gemini CLI, and while it's not dramatically different from other available CLIs, it's incredibly practical because it's free with more than reasonable usage limits. For actual development work, I still prefer an IDE, but for quick tasks, summaries of recent commits, or to converse with all the files on your disk, it's truly useful. It will definitely become part of my toolbox. The tool, with its Apache 2.0 license, supports Model Context Protocol, built-in extensions, and custom GEMINI.md files for project-specific configurations.
Let's focus on the importance of senior developer experience for vibe coding. I found Alex MacCaw's article "How to Vibe Code as a Senior Engineer" particularly insightful. Knowing what you're doing is always important, and vibe coding is just another (very powerful) tool. As Spider-Man, my favorite comic, always says: with great power comes great responsibility, and only experience allows you to manage this responsibility properly.
MacCaw describes vibe coding as a paradigm where AI models do most of the work. You write a good prompt, sketch out a plan, and let the model take over. But here's the crucial part: this isn't for juniors. It's most effective for senior engineers who have deep understanding of frameworks and libraries. The key requirements include a great scaffold with rich examples, strong rules codified in .cursor/rules, perfect context management (opening all relevant files including type definitions), using only top models like Claude 4 or Gemini 2.5 Pro, and often using audio prompts for more natural communication.
What AI struggles with reveals why seniority matters: automatic context management, TypeScript types (often defaulting to any), automatic planning, and taste in architecture. These are exactly the areas where experienced developers add value. We're in what MacCaw calls "the last hurrah" of human coding, where the tooling is magical but human judgment still matters for architecture, prompt design, and overall taste.
For productivity testing, tools like Janus are becoming essential. This tool tests AI agents with thousands of simulations to catch hallucinations, policy violations, and failures. It identifies risky outputs and provides clear, actionable insights for improvement. This is crucial for companies implementing AI agents in production, offering a systematic way to evaluate and improve AI system performance through automated testing and deep analysis of generated response quality.
Warp's new agentic development environment further pushes this evolution. With over 500,000 users, Warp goes beyond traditional IDEs and terminals, facilitating prompt-based code generation, management, and debugging with integrated AI supervision. This represents the evolution of development environments toward more natural, AI-assisted interaction.

Trend 2: Models: Improvements for Research…and for Advertising
AlphaGenome is very promising and comes from the same labs that won the Nobel Prize with AlphaFold. AI will help us better understand ourselves and the DNA variations that lead to diseases or problems. Knowledge is the foundation of scientific discovery, and this new model from DeepMind takes a long DNA sequence as input (up to 1 million base-pairs) and predicts thousands of molecular properties characterizing its regulatory activity. It can help scientists better understand genome function and disease biology, guiding new biological discoveries and the development of new treatments through analysis of sequences up to 1 million base pairs.
Gemma 3n is significant because it's one of the best small models available. Even though they're still relegated to specific tasks, having small models that run locally can be very important for building networks of models and agents with those models onboard. We'll discuss this more in the robotics section. This multimodal model by design accepts text, images, and audio as input, with two sizes optimized for on-device usage: E2B and E4B. While their raw parameter count is 5B and 8B respectively, architectural innovations allow them to run with memory footprints comparable to traditional 2B and 4B models, operating with as little as 2GB and 3GB of memory.
Imagen 4 and text in images is significant because it's fundamental for inserting advertising into generated images. What we see today in Imagen for images will soon be transferred to Veo for videos. Being able to insert advertising in generated images and videos opens new and interesting possibilities in a market that Google is particularly fond of: advertising. The latest model significantly improves text generation within images, a persistent weakness among image models. All outputs include Google's SynthID watermarking.
The research landscape is also being transformed by innovative approaches like Reinforcement Learning Teachers from Sakana AI. Using "teacher" models that explain solutions rather than solving problems from scratch, a small 7B parameter model outperformed DeepSeek R1's 671B parameters (26.3% vs 18.9% on mathematical benchmarks). Unlike traditional distillation where massive models must first learn to solve problems autonomously, these teachers receive both questions and correct answers upfront and are trained only to generate clear explanations that help student models understand. This innovative approach demonstrates how efficiency can surpass pure size in machine learning.
ElevenLabs' 11.ai represents another evolution in AI interfaces. This low-latency voice assistant uses MCP integrations with Perplexity, Linear, Slack, and Notion to execute multi-step workflows. The assistant represents a significant evolution in voice interaction with AI, allowing users to control multiple applications and services through natural voice commands, automating complex tasks that would normally require manual interaction with different platforms. During the alpha phase, they're offering free access to help gather feedback and demonstrate the potential of voice-first AI assistants.

Trend 3: Robots Are Coming
Gemini with small models running locally on robots takes a decisive step in giving robots autonomy and data collection capabilities. This push on robot models from Gemini demonstrates how much Google and DeepMind believe in robots as the next big thing. Google has detailed how Gemini 2.5 Pro and Flash, with spatially-aware multimodal reasoning and code generation, can work locally on robots to label scenes, devise task plans, and translate voice commands into executable actions via the Live API. Google's new cloud-free AI robotics model allows robots to operate with full autonomy. This is the first version of Google's robotics model that developers can customize for their specific uses, with researchers able to adapt the VLA to new tasks with just 50-100 demonstrations.
Major investments demonstrate how the robot race is intensifying and how the US and EU are trying to recover the gap they currently have with China on this research. SoftBank's massive $1T investment for Project Crystal Land in Arizona aims to replicate the scale of China's Shenzhen but with a laser focus on next-gen robotics and AI. Meanwhile, Germany's Neura Robotics aims to secure €1B in fresh funding as it gears up to launch its next-generation humanoid robot, the 4NE-1, designed to take on established players like Tesla, 1X, and Figure.
Meta's continued investment in smart glasses outlines a clear strategy, not just from Meta but the industry as a whole, indicating glasses as the most credible user interface for interacting with AI. The new Oakley Meta HSTN features Meta's AI assistant with a starting price of $399, containing Oakley's PRIZM Lens technology, 8 hours of typical use, 3K video recording, and IPX4 water resistance.
This convergence of local AI models, massive infrastructure investments, and wearable interfaces paints a clear picture: robots aren't just coming, they're already being deployed. The combination of on-device intelligence through models like Gemini 2.5 and Gemma 3n, coupled with unprecedented funding and the development of natural interfaces like smart glasses, suggests we're at an inflection point. The ability to process information locally without cloud dependencies is crucial for real-world robotics applications where latency and connectivity can't be guaranteed.

Trend 4: Money and Strategy
Apple considering Perplexity acquisition would be perfectly aligned with their AI policies, including their desire to limit errors and hallucinations by always providing references for information used in responses. Plus, Perplexity has a lot of AI talent and know-how that Apple needs. The discussions are in early stages and may not lead to an offer, but the acquisition would help Apple develop an AI-based search engine, potentially addressing the loss of its long-standing agreement with Google. Perplexity's $14 billion valuation would make this Apple's largest acquisition in history.
Sam Altman's openness to ads on ChatGPT further underscores how OpenAI is interested in the consumer market. The CEO's softened stance on advertising, calling Instagram ads "kinda cool," suggests OpenAI is exploring different monetization models to sustain the development of its increasingly expensive AI models while balancing revenue needs with user experience.
The infrastructure requirements for AI are reaching unprecedented scales. Amazon's Project Rainier involves building data centers so large they would have been considered absurd just a few years ago. The entire complex in New Carlisle, Indiana, will consume 2.2 gigawatts of electricity across 1,200 acres, forming a giant machine designed solely for artificial intelligence. This represents an infrastructure investment without precedent to support AI's growing computational needs.
Mira Murati's Thinking Machines Lab raising $2B at a $10B valuation just six months after founding demonstrates the continued appetite for AI investment. Despite keeping their research direction secret, the startup has attracted investors thanks to Murati's reputation and the high-profile AI researchers who have joined. The startup focuses on creating AI models and products that support more humanized interaction between humans and artificial intelligence.
These moves reveal a maturing AI market where strategic positioning matters as much as technical innovation. Apple's potential entry through acquisition, OpenAI's pivot toward advertising, and the massive infrastructure investments all point to an industry preparing for mainstream adoption. The willingness to invest billions in unproven startups like Thinking Machines Lab shows that the race for AI supremacy is far from over.
Key Takeaways for AI Engineers
Market Consolidation: Apple's potential $14B acquisition signals big tech's willingness to buy AI capabilities rather than build from scratch
Monetization Shift: OpenAI's advertising consideration reveals the challenge of sustaining free AI services at scale
Infrastructure Reality: 2.2 gigawatt data centers demonstrate the massive computational requirements for next-gen AI models
Action Items:
