GLM-4.6: How the 200K Context Window is Revolutionizing AI Code Collaboration
19 days ago 高效码农Introduction: When You Hit Enter and Realize Your AI Isn’t That Smart Do you remember the first time you dropped a 5,000-line Python project into an AI model? I was full of excitement, expecting the model to act like a senior engineer—untangling dependencies, fixing annoying bugs, maybe even suggesting a better architecture. Reality hit hard: by the time the model reached line 3,000, it had already forgotten half the functions, produced contradictory answers, and sometimes hallucinated classes that didn’t exist. That’s when it struck me: the size of the context window and the way reasoning is handled determine whether an …
How MIT’s PDDL-Instruct Achieves 94% Planning Accuracy in AI
19 days ago 高效码农How MIT Taught AI to Plan with 94% Accuracy: A Deep Dive into PDDL-Instruct Imagine asking a powerful AI like ChatGPT to devise a plan for building a piece of furniture. It might produce a list of steps that sound perfectly logical: “Attach leg A to panel B using screw C.” It looks right. It sounds right. But if you try to follow it, you might find that step 3 requires a tool you don’t have, or step 7 tells you to attach a part you already sealed away inside the structure in step 2. The plan is plausible-sounding nonsense. …
nvmath-python: Revolutionizing GPU Math Acceleration with Direct CUDA Integration
20 days ago 高效码农1. Why one more Python math package? Python owns the data-science mind-share, but its core linalg stack was never designed to expose every knob in NVIDIA’s hardware. If you need: Mixed-precision GEMM with fused bias–GELU in a single kernel, or In-kernel FFT for radar filtering inside your own CUDA function, or A user-written scaling function welded to an FFT so the output is already normalized, you normally descend into C++ and 300-page PDFs. nvmath-python stays in Python yet exposes the same levers. Think of it as CuPy’s older sibling who studied engineering: same household, more tools. 2. Installation: one pip …
From O(n²) to O(L·√L): How DeepSeek-V3.2-Exp Slashes Long-Context Costs Without Hurting Quality
20 days ago 高效码农A 5-minute read for engineers who need 128 K tokens tonight, not next quarter. 1. The Scene: 2 A.M. and the Context-Length Wall Li, a Beijing-based ML engineer, just wanted his 671 B model to read a 100 k-token spec and answer one obscure question. By token 60 k the GPU fans sounded like jet engines; at 90 k the server threw an OOM and the latency graph looked like Everest. Sound familiar? Long-context is the new memory wall—and the bill is paid in both dollars and sleep. The next morning DeepSeek dropped an experimental image on Docker Hub: lmsysorg/sglang:dsv32 …

Document Parsing AI Breakthrough: Alibaba’s Logics-Parsing Masters Complex Academic Papers
20 days ago 高效码农Logics-Parsing: Breaking Boundaries in Complex Document Parsing – Why I’m Impressed by Alibaba’s Open-Source “All-Rounder” When faced with academic papers featuring multi-column layouts, mathematical formulas, and chemical structures, traditional OCR tools consistently fall short—until I encountered this 7B-parameter “compact powerhouse.” I still remember the last time I needed to parse a double-column academic paper. I had to launch three different tools in sequence: one for text recognition, another for tables, and a third specifically for mathematical formulas. The entire process felt like playing a technical version of “whack-a-mole”—just as I solved one problem, another popped up. That frustration persisted until …
