llme-cli 0.1.1

A command-line interface for language models

llme, a CLI assistant for OpenAI-compatible chat servers

A simple, single-file command-line chat client compatible with the OpenAI API.

(or "I just want to quickly test my model hosted with llama.cpp but don't want to spin up openwebui")

Features

• OpenAI API Compatible: Works with any self-hosted LLM platform that supports OpenAI chat completions API.
• Extremely simple: Single file, no installation required.
• Command-line interface: Run it from the terminal.
• Tools included: Ask it to act on your file system and edit files (yolo).

The basic idea is that LLMs are trained on code and OS configuration and already (machine) learnt to select the probable tools to use and actions to take. Therefore, there is no need to teach them to use made-up function and tools with bad json schemas. Just give them a shell, a python interpreter, and let you (only) live (once).

Use it as a helping (dummy assistant) to inspect configuration, source code, run commands, and edit files.

Quickstart a local LLM server if you don't have one already

# Example with llama.cpp
brew install llama.cpp  # if you use homebrew. look at https://github.com/ggerganov/llama.cpp for other options
llama-server -hf unsloth/Qwen3-Coder-30B-A3B-Instruct-GGUF --ctx-size 0 --jinja # or whatever model you like. This one is ok.

Installation of llme

Chose your preferred installation or execution method:

# Install from PyPI (possibily an old version)
pipx install llme-cli
llme --help

# Install from GitHub directly (latest dev version)
pipx install -f git+https://github.com/privat/llme.git
llme --help

# Clone then install in development mode
git clone https://github.com/privat/llme.git
pipx install -e llme
llme --help

# Clone and run from source (no installation)
git clone https://github.com/privat/llme.git
pip install -r llme/requirements.txt
./llme/llme/main.py --help

Usage

Run an interactive chat session

llme --base-url "http://localhost:8080/v1"

or if you want to a specific model

llme --base-url "http://localhost:8080/v1" --model "NexaAI/qwen3vl-8B-Thinking-4bit-mlx"

• Ctrl-C to interrupt a response (or exit).

Setup a config (optional, but recommended):

Edit ~/.config/llme/config.toml Look at config.toml for an example. More about options and configs bellow.

I assume, from now, that there is a config file...

Run one-shots queries

Each prompt is run in order in the same chat session.

llme "What is the capital of France?" "What the content of the current directory?" "What is the current operating system?" "What is the factorial of 153?" "What is the weather at Tokyo right now?"

You can also pipe the query:

echo "What is the capital of France?" | llme

Tools included

The LLM has direct access to your shell (and files) and a python interpreter. The user is asked for confirmation before executing any command. Beware, some LLMs might be very persistent and persuasive in running dangerous commands. Do not trust the LLM blindly!

If you chose to not execute a command, it will be skipped, and you can provide an explanation to the LLM or asks for a better command.

Some LLM might insist on not using a tool, asking the user to do it manually, or just simulate the action. A better prompt engineering might help. Proposals to improve the default system prompt are always welcome.

Inspect content of files or stdin

ps aux | llme "Which process consumes the most memory?"

you can also use file paths as assets to a prompt:

llme "how many regular users and regular groups are there in these files?" /etc/passwd /etc/group

Note: the file content and the path will be given to the LLM.

Inspect images (for multimodal models)

Same as for files, but with images — duh, images are files!

llme "What is in this image?" < image.png

you can still use paths:

llme "What is in this image?" image.png

Run yolo

Note: no warranty, yada yada, etc. llme can just kill your OS and cats. Do not run the following command without understanding what it does.

sudo llme --batch --yolo "Distupgrade the system. You are root! Do as you wish."`

Options (and config)

$ llme --help
usage: llme [options...] [prompts...]

OpenAI-compatible chat CLI.

options:
  -h, --help            show this help message and exit
  -u, --base-url BASE_URL
                        API base URL [base_url]
  -m, --model MODEL     Model name [model]
  --api-key API_KEY     The API key [api_key]
  -q, --quit            Quit after processed all arguments prompts [quit]
  -b, --batch           Run non-interactively. Implies --quit. Implicit if
                        stdin is not a tty [batch]
  -p, --plain           No colors or tty fanciness. Implicit if stdout is not
                        a tty [plain]
  -o, --chat-output CHAT_OUTPUT
                        Export the full raw conversation in json
  -i, --chat-input CHAT_INPUT
                        Continue a previous (exported) conversation
  -s, --system SYSTEM_PROMPT
                        System prompt [system_prompt]
  -c, --config CONFIG   Custom configuration files
  --dump-config         Print the effective config and quit
  -v, --verbose         Increase verbosity level (can be used multiple times)
  -Y, --yolo            UNSAFE: Do not ask for confirmation before running
                        tools. Combine with --batch to reach the singularity.

Note: Run a fresh --help in case I forgot to update this README.

All options with names in brackets can be set in the config file (base_url for --base-url). They can also be set by environment variables (LLME_BASE_URL for --base-url).

For each option, the precedence order is the following:

1. The explicit option in the command line (the higher precedence)
2. The explicit config files (given by --config) in reverse order (last wins)
3. The environment variables (LLME_SOMETHING)
4. The user configuration file (~/.config/llme/config.toml)
5. The system configuration file provided by the package (the lowest precedence)

Development

I do not like Python, nor LLMs, but I needed something simple to test things quickly and play around. My goal is to keep this simple and minimal: it should fit into a single file and still be manageable.

PR are welcome!

Issues

• The various openai compatible servers implement different subsets. Compatibility is thus not yet perfect, thus causing random 4xx or 5xx responses.
• Models are really sensitive to prompts and system prompts, but you can create a custom config file for each.
• Models are really sensitive to how the messages are structured, unfortunately that is currently hardcoded in the program.

Thanks

• openwebui for an inspiration, but too complex and web oriented.
• gptme for another inspiration, but also too complex and targets too much non-local LLMs.
• openai-cli for a simpler approach I built on top of.
• llama.cpp, nexa-sdk and others for your great work.
