🎚️ Lyria 3.5 vs Suno: Control or Catalogue in 2026

Suno has spent two years being the answer to "which AI music tool." Lyria 3.5, which replaced Lyria 3 Pro in Google Flow Music on July 29, does not beat it on range. It beats it on a narrower thing that matters more than it sounds: you can tell it the tempo.

Control versus range is the whole comparison

Suno's strength has always been that you can ask it for almost anything and get something plausible. Bluegrass, drum and bass, 80s city pop, a fake film score — the range is real and Lyria does not match it.

Lyria 3.5's strength is that when it gives you something 80% right, you can fix the 20% instead of re-rolling. Tempo is settable. Vocals, drums and bass can be pushed or pulled without regenerating the arrangement. Track length is a parameter, not an outcome.

Those are different products for different jobs. If you are producing a catalogue of background beds across many styles, breadth wins. If you are scoring one edit that is 94 seconds long and needs to sit at 112 BPM, control wins and it is not close.

Where each one actually breaks

Suno. Genre range comes with genre drift — ask for something specific enough and you get a neighbouring style delivered confidently. Its lyric writing is stronger than Lyria's but still lands on competent-and-generic when the words carry the song.

Lyria 3.5. Sustained vocal notes are where this class of model gives itself away, and vibrato regularity is the specific thing to A/B. Lyric-level writing reads as the weaker of the two on published samples. And image-to-music, the flashiest feature in the release, reads mood rather than content — it will not give you a guitar because you showed it a guitar.

Both should sit fine under instrumentation at phone-speaker volume. Treat an exposed solo vocal as the test neither has publicly passed.

The licensing split

This is the part that should drive a commercial decision more than any audio quality argument.

Suno is in unresolved litigation with the major labels over training data. That is a live risk on anything you monetize, and it has not moved to a conclusion through 2026. Google's Flow Music position is separate, with its own terms.

Neither of those is a green light. Read the current terms of whichever platform you pick, before each commercial release rather than once. This category's rules have changed repeatedly and will change again.

Decision table

Your job	Take
Score to a locked picture edit	Lyria 3.5
Wide range of genres, fast	Suno
Fix an almost-right track	Lyria 3.5
Full song with extend/remaster flow	Suno
Non-English vocals, especially Japanese	Lyria 3.5
Stems into a real DAW session	Suno (Studio)
Programmatic generation via API	Neither — use ElevenLabs Music

The three-minute ceiling matters more than it reads

Length caps have quietly shaped what people make with these tools. When a model tops out near a minute, you write hooks and beds — fragments that work as background. Three minutes is a song, with room for a real second verse and a bridge that goes somewhere.

Suno has been able to reach that length for a while, but by extending: generate, extend, extend again, then remaster to smooth the joins. It works and the joins are usually invisible. It is also three or four operations where Lyria 3.5 is now one, and each extension is another chance for the arrangement to drift away from what you wanted.

The tradeoff runs the other way past three minutes. Suno's extend flow has no hard ceiling; Lyria's three-minute vocal cap is a wall. For anything long-form — a full instrumental bed for a twenty-minute video, say — Suno remains the only practical option of the two.

How we picked

A capability comparison, not a shootout — Lyria 3.5 is days old and we have not yet run matched briefs through both. Lyria feature set and date come from Google's own announcement; Suno pricing, tier and update details are carried from our Suno guide and Suno vs ElevenLabs, where they were verified against current published plans.

We did not run a blind listening test. Every published one we have seen tests isolated clips, and isolated clips are not how anyone hears music.

What didn't make the cut

A cost-per-song comparison. Suno publishes a per-song figure at the Pro tier; Lyria 3.5 is bundled into Google's plan structure and does not decompose into a comparable number. Forcing a ratio out of those two would be arithmetic, not information.

We also left out the Udio comparison — that is its own post and the litigation picture there is different again.

The honest summary

Suno if you need range and a finished-song workflow. Lyria 3.5 if you need to hit a tempo, a length, or a specific shot. That is less satisfying than picking a winner and more accurate to how the work goes — the two solve different problems, and the tempo-and-length problem did not previously have a good answer.
