Running AI coding agents at home without overspending

Summary: A widely discussed practitioner post lays out cost options for running coding agents outside expensive metered plans: self-hosting open-weight models on owned hardware, using cheap provider APIs, and fixed-price monthly plans. HN commenters reported that routing a cheap provider model (for example DeepSeek V4 flash) through a harness like opencode cost roughly $10 over two weeks, and argued that self-hosting trades per-token cost for hardware and power expense and is mostly worth it for privacy rather than raw savings.
Why it matters: As metered agent billing pushes per-developer costs up, the practical economics of cheap-API and self-hosted harnesses are now a real procurement decision for individual engineers and small teams.
