Cast AI has launched the general availability of Kimchi Coding, an autonomous AI coding agent for software development teams, moving it out of early access and into production use. Akamai is already using the system. Kimchi Coding is built around a multi-model approach, routing work to different models based on complexity and cost to reduce spending while maintaining code quality. It can be deployed inside a customer's virtual private cloud or on dedicated Nvidia B300 graphics processing units managed through Cast AI's infrastructure. In shadow-mode evaluations against a baseline using only commercial models, Kimchi Coding was 2.5 times cheaper while matching or exceeding quality on specification matching and test pass rates. The product includes spending controls, from individual application programming interface keys to wider organisational budgets, along with automated shutdown of runaway agent loops and a dashboard tracking costs by developer, team and project. Cast AI says Kimchi Coding addresses concerns through hard spending caps, data sovereignty controls and self-hosted inference options, and has ISO 27001 and SOC 2 Type II certification and is compliant with General Data Protection Regulation requirements.
