Highlights

🤖 A local AI agent

Chat with an LLM that runs entirely on your machine through llama.cpp. The new model library suggests GGUF models that fit your VRAM and shows how well each one handles tool calling. Prefer the cloud? Plug in your own OpenAI, Anthropic, Mistral, Groq or OpenRouter key. (#365)

🟥 AMD ROCm support

Modly now runs on AMD GPUs with ROCm, on Linux and Windows. See docs/running-on-amd-rocm.md. (#267)

💡 Point lights in the viewer

Add colored point lights to your scene, push their intensity up to 16×, and place them with move / rotate / scale gizmos. (#229)

🖨️ Open in OrcaSlicer

One click converts the mesh to STL and opens it straight in OrcaSlicer, imported meshes included. (#347)

🔗 Smarter workflows

Scene model artifacts flow between nodes, the new Preview Image node shows an image without running the workflow, and bounded float parameters get sliders. (#357, #205, #363)

⚙️ Model weights & stability

• Install and remove weight variants per node, shared weight groups across an extension, multiple Hugging Face sources per node. (#353, #348, #275)
• The LLM's VRAM is freed after a workflow runs, the process runner recovers from dead workers, and moving the workspace no longer loses output.
• Desktop notifications when a generation or workflow fails. (#294)
