The World You Remembered Is Already the Past: Finding Your Target in a House Where Things Keep Moving
We look at EvolvingNav, which lets a robot locate its target even in a home where objects are quietly moved around — by stamping past observations with time to reason about "where is it now" and then confirming with its own eyes.
Smart Chunking for Document Retrieval, D-RAC: How to Drop Any Enterprise Document Format Straight into RAG
A plain-language look at D-RAC, which standardizes every kind of enterprise document (PDF, Word, PPT, scans) to PDF and then uses a single multimodal LLM pass to turn it into retrieval-optimized Markdown, slashing chunking costs.
Teaching Robots "What and Where" First: A Walkthrough of GAM and 3D Grounding
An analysis of the GAM paper, which bakes 3D grounding directly into a robot foundation model. By letting you designate the target object with language, points, or boxes, GAM boosts manipulation success rates even when the scene shifts around.
Measuring AI by the Yardstick of Games — A Walkthrough of Tencent's GameHorizon Suite
Tencent ARC Lab's GameHorizon Suite is a data-and-evaluation set designed to measure gameplay ability reproducibly across short, medium, and long horizons. Here is what it can measure, what it still can't, and what's actually released yet.
ScienceIDE: Turning the World's Scientific Code into a Lab Where Agents Learn
A deep look — based on the abstract — at ScienceIDE and the PhAI-IDE model family, which train scientific agents by turning scientific code repositories into executable learning environments.
StepAudio 3 Music: A 5.5-Minute AI Music Model That Can Also Compose by Making a Plan First
An abstract-grounded deep dive into StepAudio 3 Music, which generates up to 5 minutes 30 seconds of long-form music through optional arrangement planning (ABC-CoT mode) and text control.
Game AI in the Foundation Model Era: Redrawing the Map Through Six Roles
An analysis of a survey paper that organizes the foundation-model research now woven through every stage of game development into "six roles," and clarifies what transfers across different games and what stays bound to specific contexts.
Vidu S2: A Video Generation Model You Can Talk To and Edit in Real Time
Real-time interactive video generation was first opened up by Vidu S1; S2 builds on that foundation with 720p output, dynamic references, and live stream editing. We map this "intervene while it flows" structure onto the work of an AI PM.
How ONTLE Runs: A FastAPI, MySQL, and Cloudflare Tunnel Architecture
A field-tested stack that lets a small team run many subdomains safely, walked through choice by choice — the reasoning behind each, the trade-offs it carries, and a couple of common misconceptions set straight.
A Search Index That Evolves on Its Own: How SELF-INDEX Improves RAG Without Human Hands
A close read of the SELF-INDEX framework, grounded in the paper's abstract, where the search index diagnoses its own failures and rewrites index keys to raise retrieval quality.
When EOS Tokens Disagree: The Response-Length Blowup Problem in On-Policy Distillation
Mismatched EOS tokens inflate response length in on-policy distillation; unifying equivalent EOS as one stop curbs it.
DeepSeek-V4.1-Flash: A 1M-Token MoE Model That Cuts KV Cache to a Quarter
DeepSeek has released a 552B multimodal MoE model that shrinks KV cache footprint to a quarter of its predecessor—using CSA2, FP4 KV caching, and a CED architecture—while actually pushing performance higher.
