Verdicts

MusicGen on Replicate

About $0.035 a run, billed by GPU second, with text or melody conditioning. MusicGen weights are CC-BY-NC 4.0, so no commercial use.

Stable Audio API

Pay-as-you-go credits, $0.26 a 3.0 generation and $0.20 on 2.5, failures free. Stable Audio 3.0 is async only, with polling and no webhook, and inpaint stays on 2 and 2.5.

Before you call either

MusicGen on Replicate

  1. Set duration (default 8 seconds) and model_version. The default is stereo-melody-large
  2. Use Prefer: wait for short clips and webhooks for long ones
  3. On a 429, wait the reset time in the message, about 30 seconds
  4. Switch to google/lyria-2 or minimax/music-2.5 when output must be commercial
  5. Add a payment method first, or you're held to 6 requests a minute

Stable Audio API

  1. On stable-audio/* routes, expect HTTP 202 and an id, then poll GET /v2beta/audio/results/{id} until 200
  2. Send accept: audio/* for raw bytes, not base64 JSON
  3. Set duration. It defaults to 190 seconds on 3.0
  4. Wait 60 seconds after a 429 before the next call
  5. Use the stable-audio-2 routes for inpainting. 3.0 has no inpaint route
