DeepSeek TUI

Terminal coding agent for DeepSeek V4. It runs from the deepseek command, streams reasoning blocks, edits local workspaces with approval gates, and includes an auto mode that chooses both model and thinking level per turn.

简体中文 README

Install

deepseek is distributed as Rust binaries: the dispatcher command (deepseek) and the companion TUI runtime (deepseek-tui). Pick whichever install path you already use; they all put the same commands on your PATH. The npm package is an installer/wrapper for the release binaries, not the agent runtime itself.

# 1. npm — easiest if you already use Node. The package downloads the
#    matching prebuilt Rust binaries from GitHub Releases.
npm install -g deepseek-tui

# 2. Cargo — no Node needed.
cargo install deepseek-tui-cli --locked   # `deepseek` (entry point)
cargo install deepseek-tui     --locked   # `deepseek-tui` (TUI binary)

# 3. Homebrew — macOS package manager.
brew tap Hmbown/deepseek-tui
brew install deepseek-tui

# 4. Direct download — no package manager or toolchain.
#    https://github.com/Hmbown/DeepSeek-TUI/releases
#    Prebuilt for Linux x64/ARM64, macOS x64/ARM64, Windows x64.

In mainland China, speed up the npm path with --registry=https://registry.npmmirror.com, or use the Cargo mirror below.

What Is It?

DeepSeek TUI is a coding agent that runs in your terminal. It can read and edit files, run shell commands, search the web, manage git, and coordinate sub-agents from a keyboard-driven TUI.

It is built around DeepSeek V4 (deepseek-v4-pro / deepseek-v4-flash), including 1M-token context windows, streaming reasoning blocks, and prefix-cache-aware cost reporting.

Key Features

• Auto mode — --model auto / /model auto chooses both the model and thinking level for each turn
• Thinking-mode streaming — see DeepSeek reasoning blocks as the model works
• Full tool suite — file ops, shell execution, git, web search/browse, apply-patch, sub-agents, MCP servers
• 1M-token context — context tracking, manual or configured compaction, and prefix-cache telemetry
• Three modes — Plan (read-only explore), Agent (interactive with approval), YOLO (auto-approved)
• Reasoning-effort tiers — cycle through off → high → max with Shift + Tab
• Session save/resume — checkpoint and resume long-running sessions
• Workspace rollback — side-git pre/post-turn snapshots with /restore and revert_turn, without touching your repo's .git
• Durable task queue — background tasks can survive restarts
• HTTP/SSE runtime API — deepseek serve --http for headless agent workflows
• MCP protocol — connect to Model Context Protocol servers for extended tooling; please see docs/MCP.md
• Native RLM (rlm_query) — run batched analysis through cheap deepseek-v4-flash children using the same API client
• LSP diagnostics — inline error/warning surfacing after every edit via rust-analyzer, pyright, typescript-language-server, gopls, clangd
• User memory — optional persistent note file injected into the system prompt for cross-session preferences
• Localized UI — en, ja, zh-Hans, pt-BR with auto-detection
• Live cost tracking — per-turn and session-level token usage and cost estimates; cache hit/miss breakdown
• Skills system — composable, installable instruction packs from GitHub with no backend service required

How It's Wired

deepseek (dispatcher CLI) → deepseek-tui (companion binary) → ratatui interface ↔ async engine ↔ OpenAI-compatible streaming client. Tool calls route through a typed registry (shell, file ops, git, web, sub-agents, MCP, RLM) and results stream back into the transcript. The engine manages session state, turn tracking, the durable task queue, and an LSP subsystem that feeds post-edit diagnostics into the model's context before the next reasoning step.

See docs/ARCHITECTURE.md for the full walkthrough.

Quickstart

npm install -g deepseek-tui
deepseek --version
deepseek --model auto

Prebuilt binaries are published for Linux x64, Linux ARM64 (v0.8.8+), macOS x64, macOS ARM64, and Windows x64. For other targets (musl, riscv64, FreeBSD, etc.), see Install from source or docs/INSTALL.md.

On first launch you'll be prompted for your DeepSeek API key. The key is saved to ~/.deepseek/config.toml so it works from any directory without OS credential prompts.

You can also set it ahead of time:

deepseek auth set --provider deepseek   # saves to ~/.deepseek/config.toml
deepseek auth status                    # shows the active credential source

export DEEPSEEK_API_KEY="YOUR_KEY"      # env var alternative; use ~/.zshenv for non-interactive shells
deepseek

deepseek doctor                         # verify setup

If deepseek doctor says the rejected key came from DEEPSEEK_API_KEY, remove the stale export from your shell startup file, open a fresh shell, or run deepseek auth set --provider deepseek. Use deepseek auth status to see the config, keyring, and env-var source state without printing the key. Saved config keys take precedence over the keyring and environment and are easier to rotate.

To rotate or remove a saved key: deepseek auth clear --provider deepseek.

Auto Mode

Use deepseek --model auto or /model auto when you want DeepSeek TUI to decide how much model and reasoning power a turn needs.

Auto mode controls two settings together:

• Model: deepseek-v4-flash or deepseek-v4-pro
• Thinking: off, high, or max

Before the real turn is sent, the app makes a small deepseek-v4-flash routing call with thinking off. That router looks at the latest request and recent context, then selects a concrete model and thinking level for the real request. Short/simple turns can stay on Flash with thinking off; coding, debugging, release work, architecture, security review, or ambiguous multi-step tasks can move up to Pro and/or higher thinking.

auto is local to DeepSeek TUI. The upstream API never receives model: "auto"; it receives the concrete model and thinking setting chosen for that turn. The TUI shows the selected route, and cost tracking is charged against the model that actually ran. If the router call fails or returns an invalid answer, the app falls back to a local heuristic. Sub-agents inherit auto mode unless you assign them an explicit model.

Use a fixed model or fixed thinking level when you want repeatable benchmarking, a strict cost ceiling, or a specific provider/model mapping.

Linux ARM64 (Raspberry Pi, Asahi, Graviton, HarmonyOS PC)

npm i -g deepseek-tui works on glibc-based ARM64 Linux from v0.8.8 onward. You can also download prebuilt binaries from the Releases page and place them side by side on your PATH.

China / Mirror-friendly Installation

If GitHub or npm downloads are slow from mainland China, use a Cargo registry mirror:

# ~/.cargo/config.toml
[source.crates-io]
replace-with = "tuna"

[source.tuna]
registry = "sparse+https://mirrors.tuna.tsinghua.edu.cn/crates.io-index/"

Then install both binaries (the dispatcher delegates to the TUI at runtime):

cargo install deepseek-tui-cli --locked   # provides `deepseek`
cargo install deepseek-tui     --locked   # provides `deepseek-tui`
deepseek --version

Prebuilt binaries can also be downloaded from GitHub Releases. Use DEEPSEEK_TUI_RELEASE_BASE_URL for mirrored release assets.

Windows (Scoop)

Scoop is a Windows package manager. DeepSeek TUI is listed in Scoop's main bucket, but that manifest updates independently and can lag the GitHub/npm/Cargo release. Run scoop update first, then verify the installed version with deepseek --version:

scoop update
scoop install deepseek-tui
deepseek --version

Use npm or direct GitHub release downloads when you need the newest release before Scoop's manifest catches up.

# Linux build deps (Debian/Ubuntu/RHEL):
#   sudo apt-get install -y build-essential pkg-config libdbus-1-dev
#   sudo dnf install -y gcc make pkgconf-pkg-config dbus-devel

git clone https://github.com/Hmbown/DeepSeek-TUI.git
cd DeepSeek-TUI

cargo install --path crates/cli --locked   # requires Rust 1.88+; provides `deepseek`
cargo install --path crates/tui --locked   # provides `deepseek-tui`

What's New In v0.8.17

A focused reliability release built almost entirely from community contributions. Full changelog.

• Plan-mode sandbox is now read-only — shell commands in Plan mode can no longer write to the workspace, closing a safety gap where python -c "open('f','w')" could mutate files during investigation.
• Paste-Enter no longer auto-submits — pasting multi-line text with a trailing newline stays in the composer instead of firing immediately.
• Slash menu covers all skills — /skills, /skill, and the slash autocomplete now show both project-local and global skills in sync with the system-prompt block.
• deepseek-cn preset uses the official host — defaults to https://api.deepseek.com while still recognising legacy configs with the old typo host.
• Streaming thinking blocks finalize cleanly — stream errors and restarts no longer leave partial reasoning orphaned in the transcript.
• NVIDIA NIM provider prefers its own API key — even when a legacy root DeepSeek key is present, avoiding 401s.
• Plus: /theme command for dark/light toggle, Windows UTF-8 shell output, ~30 GB snapshot-orphan cleanup, OpenRouter model-ID preservation, KV prefix-cache stabilisation, SSE decompression behind compressing gateways, npm mirror-escape-hatch guidance, and a PTY-driven TUI QA harness for regression testing.

deepseek resume <SESSION_ID>                     # resume a specific session by UUID
deepseek fork <SESSION_ID>                       # fork a session at a chosen turn
deepseek serve --http                            # HTTP/SSE API server
deepseek serve --acp                             # ACP stdio adapter for Zed/custom agents
deepseek pr <N>                                  # fetch PR and pre-seed review prompt
deepseek mcp list                                # list configured MCP servers
deepseek mcp validate                            # validate MCP config/connectivity
deepseek mcp-server                              # run dispatcher MCP stdio server
deepseek update                                  # check for and apply binary updates

Zed / ACP

DeepSeek can run as a custom Agent Client Protocol server for editors that spawn local ACP agents over stdio. In Zed, add a custom agent server:

{
  "agent_servers": {
    "DeepSeek": {
      "type": "custom",
      "command": "deepseek",
      "args": ["serve", "--acp"],
      "env": {}
    }
  }
}

The first ACP slice supports new sessions and prompt responses through your existing DeepSeek config/API key. Tool-backed editing and checkpoint replay are not exposed through ACP yet.

Keyboard Shortcuts

Full shortcut catalog: docs/KEYBINDINGS.md.

Modes

Configuration

User config: ~/.deepseek/config.toml. Project overlay: <workspace>/.deepseek/config.toml (denied: api_key, base_url, provider, mcp_config_path). config.example.toml has every option.

Key environment variables:

Set locale in settings.toml, use /config locale zh-Hans, or rely on LC_ALL/LANG to choose UI chrome and the default natural language sent to V4 models. See docs/CONFIGURATION.md and docs/MCP.md.

Models & Pricing

DeepSeek Platform defaults to https://api.deepseek.com/beta in v0.8.16 so beta-gated API features can be tested without extra setup. Set base_url = "https://api.deepseek.com" to opt out.

Legacy aliases deepseek-chat / deepseek-reasoner map to deepseek-v4-flash and retire after July 24, 2026. NVIDIA NIM variants use your NVIDIA account terms.

DeepSeek Pro rates currently reflect a limited-time 75% discount, which remains valid until 15:59 UTC on 31 May 2026. After that time, the TUI cost estimator will revert to the base Pro rates.

Publishing Your Own Skill

DeepSeek TUI discovers skills from workspace directories (.agents/skills → skills → .opencode/skills → .claude/skills → .cursor/skills) and global directories (~/.agents/skills → ~/.claude/skills → ~/.deepseek/skills). Each skill is a directory with a SKILL.md file:

~/.agents/skills/my-skill/
└── SKILL.md

Frontmatter required:

---
name: my-skill
description: Use this when DeepSeek should follow my custom workflow.
---

# My Skill
Instructions for the agent go here.

Commands: /skills (list), /skill <name> (activate), /skill new (scaffold), /skill install github:<owner>/<repo> (community), /skill update / uninstall / trust. Community installs from GitHub require no backend service. Installed skills appear in the model-visible session context; the agent can auto-select relevant skills via the load_skill tool when your task matches their descriptions.
