## Description
DeepSeek TUI now updated to CodeWhale is an open-source terminal coding agent — 95% Rust, MIT licensed, and built on DeepSeek's V4 models with a 1M token context window. Think Claude Code, but open source, self-hostable, and potentially completely free.

In this video:
✅ What DeepSeek TUI is and how the agentic loop works
✅ Why being built in Rust actually matters (single binary, OS-native sandboxing)
✅ Install in one command via npm
✅ How to run it completely FREE using NVIDIA NIM
✅ Configuration walkthrough (sandbox, approval, profiles)
✅ Live demo: explain a codebase + key shortcuts
