Tool · Hugging Face · stat: 2.8s
A new Hugging Face systems report analyzes 4,165 coding-agent turns across runtimes including vLLM and llama.cpp. The evaluation demonstrates that prefix cache reuse drops median time to first token from 69.4 seconds to 2.8 seconds, while direct frontier execution outperforms small open-weight delegation on cost per success.
Prefix caching is non-negotiable before deploying local open-weight coding agents Delegating coding tasks to small open-weight models yields higher failure rates and total costs than direct frontier model execution.
