OpenRouter reports 89% median agentic cache rate in 2026
Cache hit rates rising from the mid-60s to 89% means real savings on API bills even when model prices stay flat, since repeated context is served cheaper. Teams running agentic workflows with long, repeated system prompts should compare cache rates across providers when routing traffic. OpenRouter's routing data offers a practical benchmark for that cost comparison.
OpenRouter shared data on X (formerly Twitter) showing that the inference layer improved substantially during 2026. Median agentic cache rate rose to 89%, up from the mid-60s at the start of the year. OpenRouter notes that better caching means lower costs for users running the same models. The post was accompanied by a video and had drawn roughly 31 likes and 2 reposts at the time of capture.
We celebrate each new model as a major step forward - but the inference layer has also improved dramatically in 2026. Median agentic cache rate is up to 89% from the mid 60s to start the year. Better cache = lower cost on the same model Your browser does not support the video tag. 🔗 View on Twitter 💬 0 🔄 2 ❤️ 31 👀 2739 📊 4 ⚡
