Guillermo Rauch: Vercel Ran Cybersecurity Evals on GLM 5.3 and Calls It 'the New Open Frontier' — Cheap Enough to Scan 3× More Often
Rauch posted on Aug 16 (1,099 likes) that Vercel evaluated GLM 5.3's cybersecurity capabilities and considers it the new open-weights frontier, arguing the lower cost is 'a boon for defensive security work' because it lets teams run scans at least 3× more frequently. Replies immediately pushed the obvious counter-arguments — that the same capability profile serves offensive use, especially self-hosted, and that a Chinese open model for defensive security is a questionable trade for cost savings. The concrete builder takeaway is a cost-per-scan argument, not a capability-ceiling one.
