Bark (bark), released 2023-04
Task: Text to speech (and sound effects)
Parameters: 0.9B
Mixture-of-experts: no
Precision: fp32 / fp16
Recommended memory:
gb: 5
quant: fp32
Runs on CPU: yes
Device classes: mac, nvidia, amd, laptop
Tools: HF Transformers, suno-ai/bark, BetterTransformer
Model license: MIT (commercial use: yes)
Notes: Suno's 3-stage generative audio model (~300M per stage, ~0.9B total) that can produce speech, music and sound effects. Peaks at ~5GB VRAM in fp32 via HF Transformers; drops to ~1GB with fp16 + CPU offload, and bark-small needs ~1.9GB. CPU-only works but needs ~8GB RAM and is slow. MIT, commercial OK.
