Is Lyria 3.5 (Google) Down?

LYRIA 3.5 REACHES THE GEMINI APP AND API -- THIS IS A DISTRIBUTION EXPANSION, NOT A LAUNCH, AND IT CLOSES THIS PAGE'S JULY CAVEAT (2026-09-04, vendor-primary): **Lyria 3.5 itself shipped on 2026-07-29** (see the entry below), but into **Google Flow Music only** -- and this page explicitly flagged at the time that the announcement made 'no mention of the Gemini app, the Gemini API, Vertex AI, or MusicFX, so do not assume you can call it.' **That caveat is now resolved:** Google says Lyria 3.5, 'our best-sounding music generation model', is 'now available in the Gemini app and the Gemini API'. **Anyone reporting 2026-09-04 as the Lyria 3.5 launch date is wrong by five weeks** -- the model is unchanged; what changed is who can reach it. Google describes '**more expressive vocals and richer musical arrangements**', allowing tracks 'with higher fidelity' -- phrasing that describes 3.5 against the older Lyria line, not a new model against 3.5. **AVAILABILITY IS THE HEADLINE, AND IT IS A BIG ONE.** Google states Lyria 3.5 is '**available to all users globally on the web and in the mobile app**' -- not gated behind Google AI Pro or Ultra, unlike Gemini 3.8 Flash which shipped two days earlier to paid tiers only. **A frontier-vendor music model reaching every Gemini user worldwide at no stated cost is direct pressure on the paid-subscription music generators**, which is the context this page's Suno and Udio comparisons should now be read in. **WHAT IS NEW IN THE GEMINI APP:** select or describe a genre and choose **vocal or instrumental**; **templates** to start from (Google names background music and custom birthday tracks); and the ability to **choose short or longer tracks** -- a change from the fixed-length generation this page has documented on the Lyria 3 Pro line. **OTHER SURFACES:** **Google Flow Music** for 'artists and AI creatives', and **Google AI Studio** and **Google Vids** for developers and technologists. **WHAT GOOGLE DID NOT PUBLISH:** no API rate card in this post, no maximum track length in seconds, no benchmark or listener-preference data, and no statement on commercial usage rights or SynthID watermarking for 3.5 specifically. **Do not assume the Lyria 3 Pro terms carry over** -- they are not restated here, and this page should not extend them to 3.5 until Google does. **The July entry's SynthID question also remains open: neither the 7/29 nor the 9/04 post mentions watermarking for 3.5, which is a real gap now that the model is reachable by every Gemini user rather than by Flow Music subscribers.**

LYRIA 3.5 SHIPPED (2026-07-29, vendor post): Google released **Lyria 3.5**, '**our newest music generation model**', which it says '**delivers significant advancements across musicality, lyrics, and vocal quality**'. Google's specifics: '**improved musicality: create richer, more complex melodic structures**', better lyric prompt-adherence and structural awareness, more realistic and emotionally nuanced vocals with improved pronunciation, and greater creative control over tempo and duration. **AVAILABILITY IS THE CATCH: it is rolling out in Google Flow Music.** The announcement makes **no mention of the Gemini app, the Gemini API, Vertex AI, or MusicFX**, so do not assume you can call it -- and it says nothing about SynthID watermarking, which prior Lyria material did document. Re-check API availability before planning around it

Lyria 3 Pro is in preview on Vertex AI -- pricing for Vertex API access has not been officially disclosed as of April 2026

Daily track limits on the Google AI Pro plan (10 tracks/day) feel restrictive for active producers
