MNNCLI

Note: This project is under active development and may contain bugs or unfinished features. Use with caution.

MNNCLI is a command-line interface tool for MNN (Mobile Neural Network) that provides various functionalities for working with LLM models.

Features

• Model Management: List, download, and delete models
• Model Serving: Start a web server to serve models via HTTP API
• Model Execution: Run models with prompts or prompt files
• Benchmarking: Performance benchmarking for models
• Model Search: Search for models in the Hugging Face repository

Building

To build MNNCLI, run the following commands from the mnncli directory:

sh build.sh

The executable will be located at build_mnncli/mnncli.

Usage

List Models

./build_mnncli/mnncli list

Serve Model

./build_mnncli/mnncli serve <model_name>

Optional host/port:

./build_mnncli/mnncli serve <model_name> --host 127.0.0.1 --port 8000

Run Model

./build_mnncli/mnncli run <model_name> [-c config_path] [-p prompt] [-f prompt_file]

Benchmark Model

./build_mnncli/mnncli benchmark <model_name> [-c config_path]

Download Model

./build_mnncli/mnncli download <model_name> <repo_name>

Search Models

./build_mnncli/mnncli search <keyword>

Delete Model

./build_mnncli/mnncli delete <model_name>

HTTP API Compatibility

mnncli serve (OpenAI-compatible)

Available endpoints:

• GET /v1/models
• POST /v1/chat/completions
• POST /chat/completions (alias)

Minimal curl examples:

curl http://127.0.0.1:8000/v1/models

curl http://127.0.0.1:8000/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{
    "model": "Qwen3.5-0.8B-MNN",
    "messages": [{"role": "user", "content": "Hello"}],
    "stream": false
  }'

Anthropic-compatible (/v1/messages)

Available endpoint:

• POST /v1/messages

Minimal curl example:

curl http://127.0.0.1:8000/v1/messages \
  -H "Content-Type: application/json" \
  -H "x-api-key: dummy" \
  -d '{
    "model": "Qwen3.5-0.8B-MNN",
    "max_tokens": 128,
    "messages": [{
      "role": "user",
      "content": [{"type": "text", "text": "Hello"}]
    }]
  }'

This route is designed for Anthropic-style clients (including Claude-compatible integrations) and supports both non-stream and stream requests.

Dependencies

• OpenSSL (for HTTPS support)
• MNN core library
• LLM engine library

Notes

• The tool requires macOS 13.0+ when building on Apple platforms
• On Linux, ensure libssl-dev (or equivalent) is installed
• Models are cached in the user's cache directory
• mnncli serve currently provides OpenAI-compatible and Anthropic-compatible API routes
