ALT Table titled “Where each part runs,” comparing where execution, the agent loop and inference run for four setups. Cursor self-hosted workers: execution on customer infrastructure, agent loop and inference in the vendor cloud. GitHub Copilot with data residency: inference with the vendor, in-region. Kimchi Serverless: local harness, local loop, inference on Kimchi GPUs with regional endpoints. Kimchi Self-hosted: local harness, local loop, inference in the customer’s Kubernetes. Below: “The disconnect-my-internet test: remove all access to outside networks. Can the application, agent and model still perform the required workflow?”

ALT Benchmark results card comparing DeepSeek Harness and Kimchi on the same model and benchmark. DeepSeek Harness, best preset (creator): 47.1% task pass rate, total run cost $27.50. Kimchi: 69.4%, total run cost $36.03. Kimchi leads by 22.3 percentage points. Headline: the harness makes the difference. Terminal-Bench, GLM 5.3 Flash, maximum reasoning, October 2026.
