STAGE 1 / 7— Anti-Pattern
Section 1: The LLM Anti-Pattern vs Right-Sized Model
The Naive Generative LLM Approach:
Using an LLM to navigate a 2D/3D robotics spatial grid to plan obstacle-avoidance trajectory.
Why It Fails in Production:
LLMs lack coordinate spatial reasoning, fail on continuous spatial constraints, and produce invalid diagonal collisions.
