llmtui：本地大语言模型管理的终端用户界面

llmtui is a Rust-written terminal user interface (TUI) tool designed to manage local large language models (LLMs). It provides a unified interface for core operations: searching HuggingFace models, downloading GGUF format models, controlling llama.cpp-based inference, and running an OpenAI-compatible API service. The tool addresses the fragmentation issue in local LLM management, eliminating the need for complex command-line parameters or switching between multiple tools.

With the growing popularity of local LLM deployment, users often face challenges like fragmented tools and complex command-line operations. llmtui solves this by offering an intuitive terminal interface that covers the full workflow from model discovery to inference service, allowing users to operate without switching between multiple tools or memorizing commands.

Key features of llmtui include:

• HuggingFace Search: Supports multi-keyword search, GGUF filter, and sorting by relevance/downloads.
• Model Download: GGUF file download with pause/resume and breakpoint续传.
• Inference Control: llama.cpp integration with multiple backends (CPU/Vulkan/ROCm/CUDA), router mode for multi-model loading, and terminal chat.
• API Proxy: OpenAI-compatible API (port 49222) supporting chat completions, embeddings, and more.
• Config Presets: Model-specific settings, system prompt presets, and distributed RPC worker management.
• Practical Tools: Log panel, command line overlay, benchmark tuning, and panel size adjustment.

Tech Stack: Rust (performance/security), integrated with llama.cpp ecosystem. Backends are auto-managed (stored in ~/.local/share/llm-manager/bin/). Test Coverage: 413 test cases across modules (models, config, app, etc.). Installation:

1. Clone repo: git clone https://github.com/aginies/llmtui.git
2. Compile: cargo build --release
3. Run: cargo run Build Script: Use build.sh for common operations (build, run, release, test, etc.). Service Mode: Expose API via ./build.sh serve --model /path/to/model.gguf --api-port 49222.

• vs Ollama: Ollama uses CLI; llmtui offers a richer TUI for interactive operations.
• vs LM Studio: LM Studio is GUI-based (desktop-focused); llmtui works in terminal (ideal for servers/remote environments).
• vs llama.cpp: llama.cpp is a low-level inference engine; llmtui is a high-level management UI (complementary, not competitive).

Limitations:

• Work in progress (WIP), main support for GGUF models.
• Some advanced features under development.
• Documentation and examples need improvement.
• Certain backends require additional system dependencies. Usage Notes:
• Ensure sufficient disk space for models.
• GPU acceleration needs corresponding drivers/libraries.
• Large models require enough memory (RAM/VRAM).

llmtui provides a user-friendly, feature-rich terminal interface for local LLM management, lowering the barrier to local deployment. It integrates model search, download, inference, and API services into one tool. As an actively developed project, future updates are expected to add more features and improvements, making it an even more valuable tool for local LLM users.
