You finished editing the reel. The cuts are tight, the captions pop, and then you hit the same wall every creator hits: the music.
Trending audio might get muted. Stock libraries all sound like the same laptop ad. And hiring a composer for a 30-second clip? Not happening.
That is exactly the gap Google's Lyria 3.5 is built for. It writes full songs, with structure, lyrics, and sung vocals, from a simple text prompt. And it is now live on RentPrompts, so you can generate a track in the browser playground or call the Lyria 3.5 API and get an MP3 back for 11 joules per generation. No subscription, no setup.
Here is what the model does, how to run it, and how to write prompts that do not sound generic.
What Is Lyria 3.5?
Lyria 3.5 is Google DeepMind's newest music generation model. It launched on 29 July 2026 inside Google Flow Music, and DeepMind's model card describes it as a latent diffusion system that turns text prompts into high-quality audio.
Google called out four upgrades over earlier Lyria versions:
- Musicality: richer, more complex melodies, so tracks feel arranged instead of looped.
- Lyrics: better prompt adherence and awareness of verses and choruses.
- Vocals: more expressive singing with clearer pronunciation.
- Control: easier control over tempo and song length.
The practical shift is length. The first Lyria 3 release in the Gemini app made 30-second clips. Lyria 3.5 can produce complete songs of up to a few minutes.

Flow music is fun for experimenting. But if you are making tracks in batches, building an app, or just want Lyria next to your image and video models in one place, RentPrompts makes more sense. The model is listed with a commercial use tag.

Two things stand out for Indian creators. First, Hindi is officially supported, so you can prompt for a Hindi vocal directly. Second, the image upload lets you pass a product shot or travel photo and get music that matches its mood, which is handy for ads and travel Reels.
And because RentPrompts also hosts video models like Veo 3 Fast, Kling and Seedance, you can make the visuals and the soundtrack in the same place with the same Joules balance.
How to Use Lyria 3.5 on RentPrompts
No-code route (playground):
- Sign up on RentPrompts and recharge a few Joules from the Pricing page.
- Open the Lyria 3.5 model page from Generate → Audio.
- Write your prompt and, if you want, upload a reference image.
- Hit Run, then play or download the MP3 from the output panel.
Try a few prompts here first, so you know what style you want before writing any code.
Developer route (API):
Click Run with API on the model page and grab your API key. RentPrompts uses one endpoint for every model, so the same code works for image, video and audio.
import requests
url = "https://payload.rentprompts.com/api/v1/run"
api_key = "YOUR_API_KEY_HERE"
payload = {
"model": "lyria-3.5",
"prompt": (
"Lo-fi Hindi love song, 85 BPM, soft acoustic guitar, "
"warm male vocal, 2 minutes, verse-chorus-verse-chorus"
)
}
headers = {
"Content-Type": "application/json",
"Authorization": f"users API-Key {api_key}"
}
response = requests.post(url, headers=headers, json=payload)
print(response.json())
The response gives you the generated MP3 and, when the song has vocals, the lyrics. That makes it easy to add captions or reuse the words in your post.
If you see an insufficient balance error, top up Joules from your profile. A 401 means your API key is wrong or inactive.
How to Write Lyria 3.5 Prompts That Actually Sound Good
A vague prompt gets a vague song. "Make a happy song" usually returns something that sounds like a toothpaste jingle. The best results come from describing the track the way a producer would brief a band. Use this formula:
- Genre or fusion: "indie pop," "desert blues meets synthwave"
- Tempo and key: "96 BPM, D minor"
- Instruments with texture: "dusty tremolo guitar, fat analog bass"
- Mood and setting: "late night, open highway"
- Vocals: voice type, tone, and delivery
- Structure and length: "a 2-minute track" or timestamps like [0:00-0:15] Intro
Here is a version tuned for an Indian audience:
Indie pop Hindi song, 100 BPM, C major. Acoustic guitar, light tabla, soft synth pads. Monsoon evening, nostalgic mood. Warm female vocal singing in Hindi. [0:00-0:15] Intro: guitar with rain ambience. [0:15-0:50] Verse. [0:50-1:20] Chorus with a catchy hook. [1:20-1:30] Outro. 1 minute 30 seconds long.
Want exact words? Write your own lyrics into the prompt under the Verse and Chorus labels. Otherwise the model writes them for you.

RentPrompts marketplace has ready-made creator prompts you can remix for your brand.
Where Lyria 3.5 Fits Into a Creator Workflow
- Reels and Shorts: original background tracks that match your edit instead of a trending sound everyone else is using.
- YouTube and podcasts: custom intros, outros, and transition stings.
- D2C brands: quick jingle drafts to test before paying for a studio session.
- App builders: add a "make a song" feature at a predictable cost per track, or package your own song generator as an AI app and sell it on the RentPrompts marketplace.
- Personal gifts: a Hindi birthday or anniversary song with names written into the lyrics.
Pair it with a video model on RentPrompts and you can go from idea to finished, scored clip in one afternoon.

What to Know Before You Rely on It
Lyria 3.5 is impressive, but go in with clear expectations:
- Length cap: songs top out at a few minutes.
- Results vary: generate a few versions and pick the best. At 11 joules a try, it is cheap to iterate.
- Watermarking: DeepMind says Lyria tracks carry an inaudible SynthID watermark, so they can be identified as AI-generated.
- Rights: RentPrompts tags the model for commercial use, but read the RentPrompts and Google terms before using tracks in paid campaigns, and never prompt for a real artist's voice.
- Transparency: Google has not published full training data details, and AI music copyright is still being argued in court.
The Bottom Line
Lyria 3.5 turns "I need a custom song" into an 11-joule problem. Write a detailed prompt, hit Run on RentPrompts (or send one API call), and you get a full track with vocals, in English or Hindi. The real skill is no longer making music. It is describing it well.
