A rigid prompt harness can make 3B models behave more like 30B ones
Foxtor · reddit · 2026-07-23
A Reddit post argues that small local models work much better when prompts are treated as rigid structural harnesses instead of long, free-form instructions.
The author recommends separating the fixed skeleton from variable slots, using short Markdown templates with explicit steps, and injecting only the niche-specific variables. The goal is to reduce cognitive load and prevent small models from drifting or losing the thread mid-generation.
