Training

Teaching an AI model from scratch (pre-training) or adapting it to new data (fine-tuning). Training is the most demanding AI workload: it requires massive VRAM, fast interconnects for multi-GPU setups, and sustained high power draw for days or weeks. Pre-training large models is impractical on consumer hardware, but fine-tuning smaller models (7B–13B) is achievable with a single high-end GPU.
