DeepSeek-Reasonix
About DeepSeek-Reasonix
DeepSeek-Reasonix is a terminal-based AI coding agent designed for developers. It is engineered to work natively with DeepSeek's prefix cache, ensuring stable token costs during extended sessions. The tool is distributed as a single static Go binary, making it easy to deploy and run.
The software is config-driven, allowing users to declare providers, agents, tools, and plugins in a `reasonix.toml` file. It supports multiple models and can be composed to run two models together in separate sessions. Plugins are managed through external tools that run as subprocesses over stdio JSON-RPC.
DeepSeek-Reasonix is available for installation via npm and Homebrew, with prebuilt binaries for various operating systems and architectures. It includes features like code signing for Windows builds and supports cross-compilation to multiple targets.
