GLM 5.2 vs Opus 4.8: Coding, Context and Cost

TLDR Retries and human review affect the cost of completed coding work. The GLM 5.2 vs Claude Opus 4.8 comparison therefore needs to weigh model performance against cost per successful task, including token usage, cache reads and repeated attempts. This comparison examines coding benchmarks and independent source-code retrieval results alongside reported context limits.
