Guidance: Models trade off speed/accuracy and VRAM. Approx VRAM/speed vs large: tiny (~1GB, ~10x), base (~1GB, ~7x), small (~2GB, ~4x), medium (~5GB, ~2x), large (~10GB, 1x), turbo (~6GB, ~8x). English-only .en models often perform better for English (esp. tiny.en/base.en); differences lessen for small.en/medium.en. Actual speed varies by language, speaking rate, and hardware.
Demo mode: hardware detection unavailable.
