Iblis

Models, hardware, and first run

What model does it use?

Today Iblis generates music with ACE-Step 1.5, run on your GPU by acestep.cpp. Both are MIT-licensed. Other engines can be added later as optional plugins; each one shows its own license before you download it.

Models and graphics memory

Figures come from the signed engine and training pack manifests and the training design notes. "Declared" means the pack states it; nothing in this table is a measured benchmark yet.

| What | Model files | File size | Graphics memory (VRAM) | | --- | --- | --- | --- | | Generation, Turbo / 8 (default) | ACE-Step 1.5 turbo DiT (Q8_0), 5 Hz language model 1.7B (Q8_0), Qwen3 embedding 0.6B (Q8_0), VAE (BF16) | 2.55 + 1.98 + 0.78 + 0.34 GB | Declared minimum 4 GB; 8 GB recommended. Not measured. | | Generation, XL Turbo / 8 experiment | ACE-Step 1.5 XL turbo DiT 4B (Q4_K_M) | 2.99 GB | Not measured. | | Training a Style (LoRA), pack 0.1.1 | Embedded trainer + ACE-Step base checkpoints | 8.6 GB pack | Refuses below 6 GB; 8 GB is supported with a long-runtime warning; settings scale up at 12, 16, and 24 GB. Peak use not measured yet. |

The whole engine pack is about 9.5 GB (every file it declares, including the XL experiment). Generation needs an NVIDIA GPU with a current driver.

First run

  1. Download the installer from https://iblis.meiuxmeiux.com/download and run it. Windows SmartScreen may say "unknown publisher" because the installer is not code-signed yet: choose More info, then Run anyway.
  2. The app asks one setup question: configure everything yourself, or take the good defaults. Both lead to the same Generate screen.
  3. Create offers to install the engine pack (about 9.5 GB) from the signed catalog. Every file is checked against its published SHA-256 before use. After that, generation runs offline.
  4. Describe a song, add lyrics if you like, and press Generate. Finished tracks land in your Library on your own disk.
  5. Optional: Training installs its own pack (8.6 GB) the first time you open it.
