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.
deepseek ships as a self-contained Rust binary — no Node.js or Python
runtime is required to run it. Pick whichever path you already have on
your machine; they all land the same binary on your PATH.
# 1. npm — easiest if you already use Node. The npm package is a thin
# installer that downloads the matching prebuilt binary from GitHub
# Releases; it does NOT add a Node runtime dependency to deepseek itself.
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. Direct download — no Node, no toolchain.

# Prebuilt for Linux x64/ARM64, macOS x64/ARM64, Windows x64.In mainland China, speed up the npm path with

DeepSeek 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):

SGLANG_BASE_URL="http://localhost:30000/v1" deepseek --provider sglang --model deepseek-v4-flashA targeted patch for the V4 cache-maxing overhaul plus three runtime fixes discovered in YOLO long-session dogfooding. Full changelog.
- Cache-maxing prompt path for DeepSeek V4 — the engine skips system-prompt reassembly when the stable prefix is unchanged, moves the working-set summary out of the system prompt into per-turn metadata, and anchors the tool array with
cache_control: ephemeral. Net effect: fewer prefix rewrites, higher cache-hit rates, lower cost per turn. - 500K token compaction floor — automatic compaction refuses below 500K tokens; manual
/compactstill bypasses. The message-count trigger (a 128K-era heuristic) is removed — token budget is the sole auto-trigger. npm installresilience — retry with exponential backoff, per-attempt timeout + stall detector,HTTPS_PROXY/HTTP_PROXY/NO_PROXYsupport (pure Node, no new deps), and download progress to stderr. Driven by a community report from China wherenpm installtook 18 minutes through a CN mirror.- YOLO sandbox dropped — YOLO now uses DangerFullAccess (no sandbox), consistent with its auto-approval + trust mode posture. Previously, the WorkspaceWrite sandbox was intercepting legitimate outside-workspace writes.
- Scroll lock preserved during live streaming — scrolling up mid-stream no longer gets yanked back to the tail on the next chunk. The
user_scrolled_during_streamlock now survives render-time clamping. - Capacity controller off by default — the controller was silently clearing transcripts independent of token usage or
auto_compactsettings. Now defaults to disabled; opt-in viacapacity.enabled = true. - README clarity pass (#685) — title-cased headings, explicit prerequisites, China-friendly install variant. Thanks to @Agent-Skill-007 for this PR.

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

# 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.
