Field reports from real model users

Real posts from people using these models on actual prompts and tasks — praise and criticism alike, each linked to its source. Qualitative feedback, never scored or ranked.

Official benchmarks show reported scores. In-the-wild reports show what users hit after release: latency, cost, quota, regressions, surprising wins, and task-specific failures. These are source-linked anecdotes, not benchmark scores.

I think in terms of application functionality, quality, and design, Opus won … got stuck twice in a retry loop (had to prompt to self-correct).

Opus 4.8 in the last 48hrs is amazing … it's just very sad to go from godlike performance to barely usable some days.
