DeepSeek TUI

A terminal-native TUI and CLI for DeepSeek models, built in Rust.

For DeepSeek models (current and future model IDs). Not affiliated with DeepSeek Inc.

What is this

A terminal-native agent loop that gives DeepSeek the tools it needs to actually write code: file editing, shell execution, web search, git operations, task tracking, and MCP server integration. Coherence-aware memory compaction keeps long sessions on track without blowing up the context window.

Three modes:

• Plan — design-first, proposes before acting
• Agent — multi-step autonomous tool use
• YOLO — full auto-approve, no guardrails (preloads tools by default)

Recent highlights: workspace architecture (modular crates mirroring Codex layout), sub-agent orchestration (background workers, parallel tool calls, dependency-aware swarms), parallel tool execution (multi_tool_use.parallel), runtime HTTP/SSE API (deepseek serve --http), background task queue (/task), interactive configuration (/config), model discovery (/models), command palette (Ctrl+K), expandable tool payloads (v), persistent sidebar for live plan/todo/sub-agent state, and model context-window suffix hints (-32k, -256k).

Install

# From crates.io (requires Rust 1.85+)
cargo install deepseek-tui --locked

# Or from source
git clone https://github.com/Hmbown/DeepSeek-TUI.git
cd DeepSeek-TUI
cargo install --path crates/tui --locked   # TUI (interactive terminal)
cargo install --path crates/cli --locked   # CLI (dispatcher + server)

Setup

Create ~/.deepseek/config.toml:

api_key = "YOUR_DEEPSEEK_API_KEY"

Then run:

deepseek-tui          # interactive TUI
# or
deepseek              # CLI dispatcher (delegates to deepseek-tui for interactive use)

Tab switches modes, F1 opens help, Esc cancels a running request.

Usage

deepseek-tui                                  # interactive TUI
deepseek-tui -p "explain this in 2 sentences" # one-shot prompt
deepseek-tui --yolo                           # agent mode, all tools auto-approved
deepseek doctor                               # check your setup
deepseek models                               # list available models
deepseek serve --http                         # start HTTP/SSE API server

Within the TUI, use /config, /models, /task, and Ctrl+K command palette.

Model IDs

Common model IDs: deepseek-chat, deepseek-reasoner.

Any valid deepseek-* model ID is accepted (including future releases). Model IDs can include context-window suffix hints (-32k, -256k). To see live IDs from your configured endpoint:

Configuration

Everything lives in ~/.deepseek/config.toml. See config.example.toml for the full set of options.

Common environment overrides: DEEPSEEK_API_KEY, DEEPSEEK_BASE_URL, DEEPSEEK_CONFIG_PATH, DEEPSEEK_PROFILE, DEEPSEEK_ALLOW_SHELL, DEEPSEEK_TRUST_MODE, and DEEPSEEK_CAPACITY_*.

For the full config/env matrix (profiles, feature flags, capacity tuning, sandbox controls), see docs/CONFIGURATION.md.
