An engine for local AI inference, built on Elixir and the BEAM virtual machine.
Conversational interface for language models:
- Real-time streaming responses
- Web search integration for current information
- Document generation from research
- Message branching to compare model outputs
- Session management with chat history
- "Thinking" mode for extended chat context reasoning
- Visual node graph editor
- Batch processing with wildcards and directory iteration
- Conditional branching and loop control
Via stable-diffusion.cpp:
- SD 1.5, SDXL, SD 3.5, FLUX.1, Chroma
- Text-to-image, img2img, inpainting
- LoRA stacking, ControlNet, PhotoMaker
- VAE swapping and TAESD preview
- Video generation (Wan2.1, Wan2.2)
Via llama.cpp:
- GGUF model loading with quantization
- Prompt enhancement and templating
- Configurable generation parameters
- GroundingDINO for object detection
- Segment Anything (SAM) for mask generation
- RealESRGAN upscaling

- Backend (
/apps/leaxer_core) — Elixir application handling workflow scheduling and process supervision. Communicates with inference engines via Erlang Ports. - Frontend (
/apps/leaxer_ui) — React application with node graph editor. Connects via Phoenix WebSocket. - Desktop (
/apps/leaxer_desktop) — Tauri packaging for local deployment.
