Suno Premier credits cost 25% less than Pro: and the Sume math

Suno Premier credits cost 25 percent less than Pro credits: $8 for 2,500 is $0.0032 each, and $24 for 10,000 is $0.0024 each. Suno's pricing page lists both with commercial use rights, and sends you to its terms for limits. Past the credit price, the plans differ by the number of songs you can download each month.

Break-even against Sume depends on one number, $0.125 for each accepted Music 1.0 generation. $8 / $0.125 = 64 tracks and $24 / $0.125 = 192 tracks.

The annual option

The page lists $64 a year for Pro and $192 for Premier. Over 12 months that is $5.33 and $16.00 a month, which makes a credit $0.0021 on Pro and $0.0016 on Premier. At annual prices the equivalent Sume break-even falls to 43 tracks a month for Pro ($5.33 / $0.125) and 128 for Premier ($16 / $0.125).

Credits are not tracks, so these are not equal comparisons. A Suno generation uses credits, and Suno's page limits downloads separately; a Sume generation is one accepted job at a fixed price. Iteration changes the maths: if you make five attempts for each keeper, the cost per keeper is five attempts on both sides.

What each side gives you

Suno gives a song-oriented product with credits and downloads. Sume gives instrumentals and tracks through Music Router, where sume/music-auto picks the engine (Lyria 3.5 today) and explicit ids lyria-3.5 and lyria-3-pro pass through. The prompt can be up to 5,000 characters, with time-range cues, and Sume rejects a duration field so you set length in the words of the prompt.

Sume's docs describe the call, price and result, and make no claim about rights. Read the current Sume terms before using output commercially, as you would Suno's.

Here is a way to use the table. Count how many songs you keep in a month, not how many you generate. If you keep eight and generate forty, your spend per keeper is five attempts' worth. At Sume's $0.125 that is $0.625 per keeper, so eight keepers cost $5.00, below Suno Pro's $8. If you keep thirty and generate a hundred and fifty, the Sume cost is $18.75 against Premier's $24 plan, but the plan also covers anything else you do in it. The numbers are simple to rerun with your own attempt rate; only the attempts-per-keeper figure is yours to supply.

• Fewer than 64 tracks a month: Sume per track is cheaper than Pro at monthly prices.
• Between 64 and 192: Premier is cheaper per track if you would use all of its credits.
• Your own iteration rate: count rejected attempts, because Sume bills every accepted generation.

Verdict

Heavy iteration on a plan, occasional production tracks on a balance. The break-even is a calculator, not a verdict: put your real attempts-per-keeper into it.
