System Limitations

Cannot fine-tune 70B+ models: The 12GB VRAM is sufficient to run 70B models but not fine-tune them. Fine-tuning is supported for 7B-14B models. For larger fine-tuning tasks, consider cloud GPU rental or multi-GPU systems.

Best for 1-2 users: Designed for individual or small team use. For more concurrent users, consider our enterprise multi-GPU configurations.
