Key features

Layer streaming: fine-tune models up to 8B on a 4GB GPU by streaming decoder layers from CPU/NVMe23 training methods: SFT, DPO, ORPO, SimPO, KTO, and moreAutomatic config generation: writes task, quantization, LR, and epochs based on rules, not searchPre-flight data validation: refuses runs that won't fit on hardwareSelf-correcting: catches reward hacking mid-run rather than just haltingMigration command: converts configs from LLaMA-Factory, Axolotl, and Unsloth
