AI product Open source
Kimchi is an open-source coding-agent platform and harness developed by Cast AI. Its terminal coding-agent CLI, built on the pi-mono coding-agent SDK, connects to Kimchi's LLM infrastructure and can operate in single-model or multi-model mode. In multi-model mode, an orchestrator classifies work into roles such as planning, building, reviewing, codebase exploration, and research, then delegates tasks to configured models or model pools using tier and task metadata; requests are tagged by phase and user-defined labels for usage and cost attribution.
Kimchi includes Ferment, a persistent project-management mode that stores goals, phases, steps, decisions, memories, and append-only transition logs so work can resume across sessions. Ferment V2 provides an experimental objective controller with token budgets and independent completion evaluation. The CLI also provides Language Server Protocol tools for diagnostics, navigation, references, renaming, and type information, plus remote sessions that synchronize a working tree to a cloud sandbox and keep an agent running after the local terminal closes. Kimchi supports MCP and native Pi packages, migration of configurations from Claude Code, OpenCode, and Cursor, configurable command hooks, and installation through Homebrew, shell or PowerShell installers, or standalone binaries.
