This week, the focus shifts decisively toward fundamental research. While previous editions concentrated on direct applications, today we must examine what is happening in R&D labs because the implications for software architecture will become tangible sooner than we think. I have dedicated more space than usual to these topics, driven by a dense interview with Ilya Sutskever and a technically significant publication from Google on nested learning. This is not academic speculation; it is about understanding how memory management and learning will evolve in the models we integrate into our stacks next year.
Beyond theory, there is plenty of practice: significant news arrives from the world of agents, assisted coding, and, not least, massive investments in robotics and “Physical AI.” I will attempt to weave an organic synthesis of these developments, maintaining the technical focus that defines us.
Alongside the technical analysis, I am evaluating how to evolve the way I share my explorations. Many themes I touch upon here—from research papers to new CLIs for agents—deserve dedicated vertical deep-dives, perhaps as GitHub repositories with commented code, technical webinars, or monographic issues of this newsletter. I am currently reflecting on which format would be most useful for you to “get your hands” on these technologies, and I would appreciate your feedback or suggestions.
Finally, as you may know, I co-host a podcast dedicated to these topics. The latest episode, released Saturday and available on 📺 Youtube and 🎧 Spotify, explores many of the points you will read below. If you haven’t already, I invite you to listen and subscribe: your support is fundamental to building a solid community for exchange and debate.
Trend 1: AI Models & Research
Takeaways for AI Engineers
Beyond Scaling: Purely adding computational power is yielding diminishing returns; the focus is shifting to smarter architectures and qualitative research.
Memory Management: Nested Learning and Continual Learning are the keys to overcoming context window limits and catastrophic forgetting.
Specialization vs. Generalization: We are seeing a bifurcation between giant orchestrator models and hyper-specialized models (math, coding) acting as verifiers.
Action Items:
[Read the Google Nested Learning paper to understand future memory patterns]
[Experiment with architectures that integrate a “verifier” in the loop, inspired by DeepSeek]
What is happening this week?
The debate on the future direction of artificial intelligence found a solid anchor in the interview Ilya Sutskever gave to Dwarkesh Patel. In Ilya Sutskever: The Scaling Era is Over, the founder of Safe Superintelligence takes a clear stance: the era where exponentially increasing GPUs was enough to get better models is over. Sutskever highlights a critical distinction between scaling and research. Scaling has a simple formula attractive to investors (more resources equals more powerful models), but long-term research, while less linear, is the only path to unlock true reasoning capabilities (ASI). A passage that struck me particularly was his analysis of the misalignment between benchmarks and business: impressive results in synthetic tests often have very low impact on real business metrics, a signal that current metrics do not capture actual economic value.
This concept of “architectural quality” over “brute force” connects directly to what I consider the most important publication of the week. Google Research introduced a new approach with Google introduces Nested Learning. I invite you to read it carefully because we might be facing an impact similar to that generated by “Attention is all you need” in 2017. The paper addresses the problem of continual learning and catastrophic forgetting (the model forgets old tasks while learning new ones). The researchers developed “Hope,” an architecture that, inspired by the human brain, uses memory modules updated at different frequencies. This approach unifies optimization algorithms and architecture into a system of nested problems. For us engineers, this means the evolution toward true AGI or Super Intelligence will necessarily pass through the ability of models to handle persistent and efficient long-term memory, ceasing to be “stateless” systems between one training session and another.
While research looks to the future, the market is releasing tools that apply these principles of specialization and reasoning today. Anthropic responded to the competition with Anthropic launches Claude Opus 4.5, positioning it as a high-level orchestrator. The model is designed to manage teams of smaller models, setting new records in coding and, interestingly for those managing enterprise budgets, promising a 66% cost reduction compared to the previous version.
In parallel, we see the emergence of advanced reasoning techniques applied to specific domains. DeepSeek-Math-V2: Advanced Mathematical Reasoning demonstrates how using an LLM-based verifier (Self-Verifiable Mathematical Reasoning) can incentivize the model to check its own intermediate steps, achieving “gold” level results at IMO competitions. It confirms that the “generate-verify” loop is superior to single inference. On the open-source and scalable architecture front, INTELLECT-3: 100B MoE with large-scale RL was released. Trained on top of GLM 4.5 Air with decentralized Reinforcement Learning techniques, it shows how state-of-the-art performance in math and coding can be achieved even without the resources of a centralized hyperscaler.
The visual model sector and technical education also offer relevant insights. Black Forest Labs presented Flux.2: The new generation of visual models, with an open-weight “Dev” variant integrating with Mistral-3 for vision-language capabilities, optimized even for future RTX5090s. For those wanting to understand what happens “under the hood” of these systems, Sebastian Raschka released Olmo 3 From Scratch, a notebook implementing the OLMo 3 architecture from zero. Resources like this, or the tutorials for Qwen and Gemma, are fundamental for us to avoid treating these models as mere “black boxes.” There is much to study, and I personally will dedicate the coming weeks to deepening these new dynamics of memory and verification.
Trend 2: Coding & CLI Assistants
Takeaways for AI Engineers
Structured Prompting: Coding output quality depends increasingly on the ability to provide context and structured instructions (meta-prompting).
Vibe Coding: The barrier to entry lowers; describing desired behavior (the “vibe”) is becoming a valid development method for rapid prototypes.
Agent Standardization: Using CLIs and standards for agent creation is necessary to avoid technical debt in LLM-based architectures.
Action Items:
[Install and test Gemini CLI for system tasks and debugging]
[Integrate libraries of pre-validated scientific/technical prompts into your workflows]
What is happening this week?
The evolution of development support tools is radically changing our daily workflow. We are no longer talking just about autocomplete, but about complex interaction with the operating system and requirements abstraction. A clear example is the collection of Gemini CLI Tips & Tricks. This tool transforms the Google assistant into a true terminal “pair programmer,” capable not only of writing code but of reasoning on multi-step plans, debugging, and automating system tasks. Mastery of these CLI tools will become an indispensable skill for operational efficiency.
However, the effectiveness of these tools strictly depends on how we guide them. It is fundamental to understand that the prompt is not a passive request, but a technical specification. The Prompt Guide for “Nano Banana” (Gemini Image Gen) is an excellent example of how constructing effective instructions (in this case for coherent visual narratives) requires method, going as far as defining “meta-prompts” to help the user. The same rigor is needed in scientific and technical fields, as demonstrated by Claude Scientific Skills, a repository collecting over 123 ready-to-use skills for Claude. Using optimized configurations for specific tasks (data analysis, complex reasoning) is what distinguishes amateur from professional LLM usage.
This ability to guide AI is leading to the birth of the “Vibe Coding” phenomenon. With the launch of LingGuang: “Vibe Coding” App by Ant Group, we see a multimodal assistant that allows creating mini-programs and interactive interfaces simply by describing the idea in natural language. This approach democratizes development, but for us engineers, it means we must concentrate on architecture and business logic, leaving implementation details to AI. Finally, to prevent this proliferation of agents and assistants from becoming unmanageable, standards like Better Agents: Standards for Building Agents are emerging. Tools that generate optimized structures and guide framework choices are essential to ensure our “artificial colleagues” are built following solid industrial best practices.
Trend 3: AI Agents
Takeaways for AI Engineers
Adaptive Interfaces: Natural language input has too high entropy for certain tasks; dynamically generated UIs (UI as output) reduce errors and improve usability.
Agent Fragility: Tool abstraction is often a breaking point; manually managing caching and real tool usage is still necessary.
Dual Memory: A “universal memory” does not exist; semantic memory (preferences) and working memory (task logs) must be designed distinctly.
Action Items:
[Evaluate adopting MCP-UI to make internal agents usable by non-technical users]
[Review agent architecture by separating preference storage from operational storage]
What is happening this week?
The AI agent sector is maturing, moving from initial enthusiasm toward an engineering phase more conscious of the difficulties. A central theme is the interface: although chat is powerful, natural language is often verbose and ambiguous. To reduce entropy in inputs and facilitate use in specific contexts (industrial or mobile), there is a push toward AI-generated UIs. MCP-UI: User Interfaces for AI Agents extends the MCP protocol allowing agents to render complete HTML components (forms, dashboards) directly in the conversation. Similarly, Google Stitch: UI Design from Text and Images and the community a2a-ui: Community UI for Agents work in the same direction: transforming text into functional interfaces, reducing iteration times and improving human-machine or agent-agent interaction.
Designing these systems remains complex, however. The article Agent Design Is Still Hard offers a lucid analysis of how software abstractions tend to break when agents must use real tools, highlighting how Reinforcement Learning and manual cache management are far more critical than expected. To support this complexity, Anthropic Advanced Tool Use introduced features for on-demand tool search and multiple programmatic calls, concrete attempts to make orchestration more robust and economical.
Another fundamental pillar is memory. The analysis Universal LLM Memory Does Not Exist correctly dismantles the myth of a single “storehouse” of memories. To build effective agents, we must design architectures that sharply separate semantic memory (who the user is, long-term history) from working memory (current files, error logs). This connects to the vision of AI Infrastructure in the “Era of Experience”, which predicts a shift from predictive models to systems that “gain experience” by interacting with the environment via RL. Successful examples of this practical application are starting to appear, as demonstrated by Agentic Reviewer by Andrew Ng, a system that exceeded human correlation in reviewing academic papers, proving that careful agent design can surpass human expert performance in complex tasks.
Trend 4: Strategies between Business and Robotics
Takeaways for AI Engineers
UX as Moat: Competition is playing out on extreme personalization (memory) and vertical integration (shopping, checkout), reducing friction for the user.
Embodied AI: AI is leaving screens. Software skills (multimodal models) are merging with robotic hardware; knowing LLM-based “Robot OS” will be a competitive advantage.
Action Items:
[Analyze OpenAI’s “Shopping Research” flows to understand how they structure intent recognition]
[Monitor SDKs released by companies like Physical Intelligence]
What is happening this week?
In the business realm, the battle between giants is being fought on the grounds of User Experience and user retention. Perplexity Adds Memory to AI Assistants introduces long-term memory to prevent users from having to repeat instructions (”context engineering”), creating an assistant that becomes more useful over time. In parallel, OpenAI launches “Shopping Research” directly challenges Google in e-commerce. Transforming chat into a complete commercial platform with “Instant Checkout” is a massive strategic move: it is not just about answering questions, but closing economic transactions directly in the AI interface.
But the most interesting frontier concerns AI exiting the digital world. We are witnessing massive investments in “Physical AI.” Physical Intelligence raises $600M, with backing from Bezos and OpenAI, to create a “universal brain” ($\pi_0$ model) capable of controlling diverse robotic hardware. It is no longer just code running on servers, but software acting in the physical world. Confirming this trend, DeepMind hires Boston Dynamics CTO. The goal is clear: transform Gemini into an operating system for robots, uniting Google’s intelligence with the hardware experience of those who created iconic machines like Atlas. For us developers, this opens scenarios where our skills on agents and multimodal models will be directly applicable to controlling physical machines.
