lm-launcher

A small Swing GUI for managing local GGUF models and launching apps with model-dependent command-line placeholders.

What it does

• scans a configured models directory for .gguf files
• stores per-model settings in models.json
• stores app launch definitions in apps.json
• launches apps with placeholders resolved from the selected model

Model settings

Each model can store:

• context length
• max context length
• threads
• GPU layers
• prompt template
• temperature
• top-p
• top-k
• min-p

The main window also provides sliders for quickly adjusting launch-time values for:

• context length
• threads
• GPU layers
• temperature
• top-p
• top-k
• min-p

App placeholders

Use these tokens in app arguments:

• MODEL
• CONTEXT_SIZE
• THREADS
• GPU_LAYERS
• TEMP
• TOP_P
• TOP_K
• MIN_P

Example:

-m MODEL -c CONTEXT_SIZE -t THREADS -ngl GPU_LAYERS --temp TEMP --top-p TOP_P --top-k TOP_K --min-p MIN_P

Files

• lm-launcher.properties – launcher configuration
• models.json – saved model settings
• apps.json – saved app definitions
• run.sh – starts the packaged launcher jar

Run

./run.sh
