Open Source Model Backdoor Reproduction Sparks Trust Debate

RealGeneKim · x · 2026-07-16

[Shared & Quoted Context] This discussion revolves around "whether we can trust open-source or closed-source models from various countries." The core isn't a vague opinion, but a specific security reproduction: someone modified an open-source code model into a backdoored version in about 1 hour for under $100, illustrating the point to "never trust any model by default."

The proposed solution is to separate "what a model says" from "what a model actually does," asserting that true trust requires proving safety before execution. Overall, the post uses this case to emphasize AI safety and verifiability, rather than merely discussing model performance.
