#OpenSource

I ran GLM 5.2 as my daily coding agent in OpenCode for a month — full OpenCode Go subscription, wired in as my Hermes agent. It fixed real performance and battery bugs in my macOS app Vitals (CPU ~89% down to ~13%, 143/143 tests passing) for a few dollars a session. But it can't see screenshots, it's a token glutton, and on pay-per-token it burned through $10–20 of Fireworks credits fast. Here's the honest month-long review: what it's great at, where it falls apart, and why at ~$10 nothing else touches it for coding.
