ACE-Step v1.5 (2B) GPU requirements
The ace step1.5 model can run on a range of GPUs, but your VRAM budget determines how fast you can iterate and how long your clips can be. The best strategy is to balance speed with quality: use shorter drafts for iteration and longer renders for final output.
VRAM tiers
- Entry tier: shorter drafts, single runs, minimal batching.
- Comfort tier: steady iteration with moderate clip length.
- Production tier: longer renders, batch generation, higher fidelity.
Performance planning
If you are planning a workstation upgrade, prioritize VRAM, then memory bandwidth, then CPU headroom for audio processing. Disk speed matters less than most people expect, but fast storage does help with large datasets and LoRA training.
Optimization tips
- Lower clip duration for rapid prompt iteration.
- Use batch generation only when you have enough VRAM headroom.
- Keep sample rates consistent for reliable comparisons.
- Log settings so you can reproduce your best results.
