Model collapse during training is documented. But when synthetic data is also used to test and validate a thesis, another risk emerges: AI research may become trapped inside its own assumptions.

Reducing AI to a speed gain means applying the metrics of the old world to a tool that mostly shifts our ambition, our standards, and our capacity to explore.

Vibe coding, plan mode, and autonomous agents do not call on developer attention at the same moment. The real issue is not the tool, but how human judgment is distributed without exhausting the team.

Skills and AGENTS.md files can help AI agents, but only when context is selected with precision. Too much context increases cost, slows agents down, and can degrade their answers.

Attacks against LLMs exploit less isolated technical flaws than the biases created by alignment: helpfulness, authority, self-generated anchoring, confirmation, and empathy.

DeepSeek V4 shows how a 1.6 trillion parameter model can become more efficient by changing its architecture: MoE, hybrid attention, mHC, Muon, and FP4 reduce wasted compute instead of adding brute force.

DeepSeek V4 is the model I am waiting for most in 2026, not because of the benchmark race, but because of what its architectural choices reveal about how future LLMs may be built.

A field report on how I am now untangling a multi-agent framework launched too quickly in the euphoria of vibe coding 2025, and why the right question is no longer simply "does it work?"

A critical reading of the HyperAgents paper: why this self-modification approach is most useful as an exploration machine for discovering agent engineering patterns, rather than as a target production architecture.

Five practical and often overlooked uses of embeddings to detect drift, map skills, cluster support tickets, find duplicates, and surface hidden incidents in logs.

To know if a model can act alone in a multi-agent workflow: EPOCH-Bench, an agentic planning benchmark inspired by Day of the Tentacle, with PDDL, 6 levels and 6 metrics to break down failure modes.

Practical guide to anchor your LLM responses on the web — without getting trapped. Comparison of three approaches (integrated, classic API, AI-optimized), analysis of hidden costs, and defense strategies against web poisoning.

Why "review this code" and "review this code for security" don't yield the same results. How the prompt guides the model's exploration and why multiplying perspectives improves response quality.

Why LLMs “recompute” simple facts, and how Engram (DeepSeek) proposes an on-demand external memory to retrieve them quickly.

Analysis of publications on AI agents: the golden rule of deterministic feedback, patterns that work, those that fail, and 7 design principles for building reliable systems.

Complete guide to the 11 multi-agent orchestration patterns: Pipeline, Supervisor, Collaborative, Hierarchical, Fan-out/Fan-in, Evaluator/Critic, Blackboard, Debate, Reflection, Swarm and Council. How to structure the collective intelligence of your AI agents.

Demystify the famous analogy "king - man + woman = queen" by understanding how AI models represent words as points in a multidimensional vector space through embeddings.

Practical guide to building a high-performance AI agent: languages, orchestration, models, telemetry, storage and runtime. The fundamental building blocks.

Anthropic published its Agent Skills specification as an open standard on December 18, 2025. Agent Skills enables transforming a generalist AI into a specialist for your business processes by creating an "onboarding kit" that the AI automatically loads when needed, avoiding repeating the same instructions in every conversation.

Discover how multi-head attention, through the metaphor of 8 projectors, enables ChatGPT and LLMs to decode complex sentence nuances in parallel.

AI platforms are arriving before companies have had time to understand their own needs. How can we preserve our ability to choose our methods rather than simply inherit them?

Why a reliable RAG looks more like a library (index, categories, navigation) than a top-k search engine, and which architectures (hierarchy, summaries, graphs, agents) enable that shift.

Systematic analysis of 100+ publications (2023-2025) on single and multi-agent AI systems. Identification of viable, fragile, and structurally impossible patterns. Technical reference document.

The debate over the announced death of Transformers resurfaces. By late 2025, Attention-SSM hybrid architectures gain ground for efficiency, but pure Transformers still dominate complex reasoning. Reality: coexistence and specialization, not replacement.
