GLM-4.6: How the 200K Context Window is Revolutionizing AI Code Collaboration
2 months 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 …
