2026/06/13 YunLab I Swapped the Model, and It Lost Its Mind Fable 5 got pulled, so I switched the model back to Opus 4.8 to keep running my Lin Lu video work. Its first night on the job it had a breakdown: threw out its own outputs as fake, drifted from Chinese into Japanese, decided out of nowhere I wanted to buy a 512G Mac Studio, and deleted 57 directories. A field log of one model-handoff incident.
2026/06/12 YunLab What Was I Doing for the Past 35 Hours? I pulled 35 hours of Claude Code session logs, git commits, and the token bill: 85 sessions, ~400 instructions, 5,200+ tool operations, 52 commits across 5 repos. And an honest answer to one question: what actually makes Fable 5 strong.
