Lyria 3.5 API Pricing, Model ID and Developer Setup

Google's current Lyria 3.5 API uses the lyria-3.5 model ID and charges $0.08 per full-song request, with text and image input support through the Gemini API.

01

Current Lyria 3.5 API pricing

Google's current Gemini Developer API pricing page lists lyria-3.5 at $0.08 per full-song request. The free API tier is listed as unavailable for this model.

Do not convert this into a token-price estimate: Google publishes Lyria 3.5 pricing per request for the music-generation endpoint.

02

Use the current model ID

The live model page and September 3 release notes identify the current full-song model as lyria-3.5. Google labels it as public preview.

03

Supported inputs and outputs

Lyria 3.5 accepts text and image inputs and outputs audio plus lyrics text. Google's current model page specifies MP3 output and 44.1 kHz stereo audio for the full-song model.

The model has a 131,072-token input limit, but it should still be treated as a specialized generation model rather than a general-purpose reasoning model.

04

Basic API pattern

Google's current music-generation guide uses the Interactions API for Lyria. A request identifies lyria-3.5 and supplies the music brief as input; developers can then read generated audio and text output from the interaction response.

Production code should validate the current response schema, handle missing or failed outputs explicitly and avoid assuming every response part contains audio.

05

What Lyria 3.5 does not support

Google marks function calling, search grounding, code execution, structured outputs, Live API, caching and several other general Gemini capabilities as unsupported for Lyria 3.5.

If an application needs planning, research or tool use before music generation, use a general Gemini model for orchestration and hand the final music brief to Lyria 3.5 for the audio-generation step.

06

Simple cost examples

  • 100 full-song requests = $8
  • 1,000 full-song requests = $80
  • 10,000 full-song requests = $800

These are direct arithmetic examples from Google's current $0.08 request price. They do not include storage, delivery, moderation, orchestration, hosting or other application costs.

07

What to verify before production

  • the active model ID and preview status
  • project billing and current quotas
  • region and account access
  • response handling and retry behavior
  • storage and delivery costs outside the model request
  • current Google terms for the intended use case

Pricing alone is not a capacity or licensing guarantee. Recheck Google's live documentation before committing production budgets or customer-facing rights claims.
