Week 22, 2026 — LLM Training & Scaling Laws
This week brought transformative advances in understanding how large language models scale and train — from a unified theory of scaling failures to practical recipes for MoE hyperparameter transfer and data mixture auditing. Shannon Scaling Law Unifies Training Phenomena Xu Ouyang and colleagues proposed the Shannon Scaling Law, treating LLM training as information transmission over…

Scientific AI: When Models Become Scientists
42 papers surveyed, 12 core papers retained, 6 miscategorized filtered out | May 2025 – May 2026 — The story of Scientific AI in 2025–2026 isn’t just about applying machine learning to science problems — that’s been happening for years. What changed this year is that AI models began to look less like tools and…

Open Source Models: Four Breakthroughs That Changed What “Open” Means
60 papers surveyed, 36 core papers retained, 13 miscategorized filtered out | May 2025 – May 2026 — The “can open models match closed models?” debate is over. For many tasks, the answer is a clear yes. But the 2025–2026 research cycle asked a more interesting question: Now that open models work, what can we…

Code & Math AI: When Proving Programs Correct Became Practical
The year AI stopped guessing and started proving — how agentic theorem proving, I/O-optimal attention, and domain specialization converged (56 papers surveyed, 33 miscategorized filtered out) — In May 2025, if you asked an LLM to write a program and formally verify it, you’d get back plausible-looking code that probably didn’t compile and definitely hadn’t…

The Year Robots Learned to Learn — With 180 Demonstrations Instead of 10,000
How instrumentation, point tracking, and particle dynamics are rewriting the economics of robotic learning (53 papers surveyed, May 2025–May 2026) — Everyone knows the problem with robotics: robots can’t generalize. A factory arm that picks one part flawlessly for five years breaks when you move the bin six inches. A strawberry-picking robot that works in…

The Year AI Learned to Plan Before It Rendered: Video & Image Generation’s Architecture Shift
37 papers surveyed | May 2025 – May 2026 — Video and image generation research hit a turning point this year. The field moved past the era of “more compute, better pixels” and discovered something more fundamental: the hardest problems in visual generation aren’t about rendering — they’re about planning what to render. The central…

Post-Training Is the New Pre-Training: Why RL Training Loops Are Reshaping AI in 2026
51 papers analyzed | May 2025 – May 2026 — If you think the biggest AI breakthroughs come from bigger models trained on more data, you’re looking in the wrong place. The most important AI research of 2025–2026 didn’t happen during pre-training. It happened after — in the post-training phase where models learn to actually…

The Year Alignment Got Empirical: When, Where, and for Whom Do Models Fail?
55 papers surveyed | May 2025 – May 2026 — For years, AI alignment lived in the realm of principles. Papers opened with “it is important that AI systems align with human values” and closed with hand-waved suggestions for future work. In 2025–2026, that changed. The field stopped asking is the model safe? and started…

The Agent Stack Is Being Rewritten
Orchestration, skills, and security — the year agent research grew up. May 2025 – May 2026 | 37 papers surveyed — A year ago, if you wanted to build an AI agent, you picked a framework: LangGraph, CrewAI, AutoGen, Google ADK, OpenAI Agents SDK. These frameworks — collectively exceeding 290,000 GitHub stars — defined the…
