Claude Opus 4.5 vs. GLM-5.2: Comparative Model Analysis

As the local LLM landscape expands with multiple competitive models, independent benchmarking becomes essential for practitioners making deployment decisions. This comparative analysis between Claude Opus 4.5 and GLM-5.2 provides insights into performance tradeoffs, model capabilities, and suitability for different use cases.

For those evaluating which models to self-host or fine-tune locally, understanding relative performance across reasoning tasks, speed metrics, and resource requirements is crucial. The comparison helps identify which model families offer the best value proposition for specific constraints—whether optimizing for inference latency, memory footprint, or raw reasoning capability.

This benchmark analysis is particularly valuable as open alternatives to proprietary models mature, allowing local deployment practitioners to make evidence-based decisions about which models to standardize on within their infrastructure.
