SynConfRoute: Syntax-Aware Routing Keeps Code Private by Running Easy Completions on Local 1-3B Models
arXiv·medium signal
SynConfRoute uses syntax-aware confidence signals to route code completion requests between a small local CodeLLM (1B-3B, runs on developer workstation GPU) and a larger cloud model. Easy completions stay local — code never leaves the machine. Hard tasks route to the cloud. Directly addresses the enterprise tension between code privacy and completion quality, with no model retraining required.
