Cast AI's Kimchi Coding hits GA: a multi-model coding agent claiming 2.5x lower cost with full data sovereignty

Cast AI·medium signal

GA'd July 15, 2026, Kimchi autonomously routes each coding task to the right model at the right cost — hard work to frontier models, routine work to open-weight ones — and in shadow-mode evals against a commercial-only baseline reports 2.5x cheaper with matching-or-better spec-match and test-pass rates. It runs as a standalone deployment in a customer VPC or on dedicated Nvidia B300 GPUs, with ISO 27001, SOC 2 Type II, GDPR compliance, and air-gap support across AWS/GCP/Azure/on-prem. Claims are vendor-sourced (single press release), so importance is capped pending independent benchmarks.
