This terminal-native coding agent is built around DeepSeek V4's 1M-token context window and prefix cache capability. It is distributed as a single binary and requires no Node.js or Python runtime. It also includes an MCP client, a sandbox, and a durable task queue out of the box.
Before proceeding, ensure that Node.js and npm are installed.
node --version
npm --versionIf Node.js and npm are not installed in your environment, refer to the installation guides provided below:
- English version: https://nodejs.org/en/download
- Chinese version: https://nodejs.org/zh-cn/download
Select the version that best matches your device specifications and operating system.
Install the deepseek-tui now:
npm install -g deepseek-tui
# When installing deepseek-tui in China's internet environment, you can use an npm mirror to speed up the installation process.
# npm install -g deepseek-tui@latest --registry=https://registry.npmmirror.comDeepSeek TUI is a coding agent that runs entirely in your terminal. It gives DeepSeek's frontier models direct access to your workspace — reading and editing files, running shell commands, searching the web, managing git, and orchestrating sub-agents — all through a fast, keyboard-driven TUI.
Built for DeepSeek V4 (deepseek-v4-pro / deepseek-v4-flash) with 1M-token context window and native thinking-mode (chain-of-thought) streaming.
- Native RLM (
rlm_query) — fans out 1–16 cheapdeepseek-v4-flashchildren in parallel for batched analysis and parallel reasoning, all against the existing API client - Thinking-mode streaming — watch the model's chain-of-thought unfold in real time as it works through your tasks
- Full tool suite — file ops, shell execution, git, web search/browse, apply-patch, sub-agents, MCP servers
- 1M-token context — automatic intelligent compaction when context fills up; prefix-cache aware for cost efficiency
- Three modes — Plan (read-only explore), Agent (interactive with approval), YOLO (auto-approved)
- Reasoning-effort tiers — cycle through
off → high → maxwithShift + Tab - Session save/resume — checkpoint and resume long-running sessions
- Workspace rollback — side-git pre/post-turn snapshots with
/restoreandrevert_turn, without touching your repo's.git - Durable task queue — background tasks survive restarts; think scheduled automation, long-running reviews
- HTTP/SSE runtime API —
deepseek serve --httpfor headless agent workflows - MCP protocol — connect to Model Context Protocol servers for extended tooling; please see docs/MCP.md
- 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-BRwith 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
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.
npm install -g deepseek-tui
deepseek --version
deepseekPrebuilt 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
export DEEPSEEK_API_KEY="YOUR_KEY" # env var alternative; use ~/.zshenv for non-interactive shells
deepseek
deepseek doctor # verify setupTo rotate or remove a saved key:
deepseek auth clear --provider deepseek.
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.
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 --versionPrebuilt binaries can also be downloaded from GitHub Releases. Use DEEPSEEK_TUI_RELEASE_BASE_URL for mirrored release assets.
Install from source
Works on any Tier-1 Rust target — including musl, riscv64, FreeBSD, and older ARM64 distros.
# 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 1.85+; provides `deepseek`
cargo install --path crates/tui --locked # provides `deepseek-tui`Both binaries are required. Cross-compilation and platform-specific notes: docs/INSTALL.md.

- Stacked toast overlay — status toasts queue and render together instead of overwriting each other
- File @-mention frecency — file mention suggestions learn from recent selections (
~/.deepseek/file-frecency.jsonl) - Runtime API expansion — CORS origins config, full thread editing (
PATCH /v1/threads/{id}),archived_onlyquery filter, aggregate usage endpoint (GET /v1/usage?group_by=day|model|provider|thread) - Language picker on first run — new onboarding step selects locale before entering the API key
- OPENCODE shell.env hook — lifecycle hooks can inject shell environment into spawned commands
- Cache-aware compaction — compaction calls reuse cached prompt prefixes, cutting
/compactcosts significantly - glibc 2.28 baseline — prebuilts now target glibc 2.28 (via
cargo zigbuild), covering older distros; npm postinstall fails fast with a clear source-build message when incompatible - Better markdown rendering — transcript now handles tables, bold/italic, and horizontal rules; no more infinite loops on unclosed markers
- MCP SIGTERM on shutdown — stdio servers receive SIGTERM with a 2-second grace period instead of SIGKILL
- Shell-child PDEATHSIG on Linux — children auto-SIGTERM when the parent exits, closing a leak window
- Windows Terminal paste fix — Ctrl/Cmd+V during onboarding now works correctly
- Terminal startup repaint — no more stale background rows above the first frame
- Slash-prefix Enter activation — typing
/moand pressing Enter activates the first match - Shell
cwdboundary validation — path escape returnsPathEscapeon out-of-workspacecwd, consistent with file tools

UI locale is separate from model language — set locale in settings.toml, use /config locale zh-Hans, or rely on LC_ALL/LANG. See docs/CONFIGURATION.md and docs/MCP.md.

DeepSeek Pro rates currently reflect a limited-time 75% discount, which remains valid until 15:59 UTC on 5 May 2026. After that time, the TUI cost estimator will revert to the base Pro rates.
DeepSeek TUI discovers skills from workspace directories (.agents/skills → skills → .opencode/skills → .claude/skills) and the global ~/.deepseek/skills. Each skill is a directory with a SKILL.md file:
~/.deepseek/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.
