What runs well on the B300.
- Fine-tuningTrain on your data. Keep the weights.
- LLM inferenceAn OpenAI-compatible endpoint with vLLM.
- Batch jobsThousands of files, one session.
- RecipesLoRA fine-tuningFine-tune an open-weight LLM with LoRA or QLoRA using the Hugging Face TRL CLI on a Node Lodge GPU, then copy the adapter off the machine.
- RecipesvLLMServe an open-weight LLM with vLLM on a Node Lodge machine. Install with uv, start the OpenAI-compatible server, query it through an SSH tunnel.
