Together’s GLM 5.3 performance draws praise in a post citing OpenRouter

Citing OpenRouter statistics, a September 11 post touts Together’s performance serving GLM 5.3 and GLM 5.3 Flash. The author claims top-decile tokens per second, latency and cache rate, with volumes representing 23% and 30% of all OpenRouter traffic, respectively. The post also says OpenRouter accounts for a fraction of Together’s overall API traffic. Its broader argument: running AI models for agentic applications at scale requires optimizing across metrics while maintaining reliability, rather than maximizing a single measure.
