Google: Lyria 3 Pro Preview

This model does one plain thing: it generates full-length songs from your input, as part of Google's Lyria 3 music-generation family delivered through the Gemini API. Full songs are priced at $0.08 each, and the output is high-quality 48kHz audio, which suits a concrete job like scoring a batch of short marketing videos with original tracks so you avoid licensing stock music. Through OpenRouter it is listed as free to use, and it carries a very large context window of 1,048,576 tokens alongside image input, though it offers no tool or function calling. Compared with the Gemini video alternatives it sits beside here, such as Gemini 3.5 Flash and Gemini Flash Latest, its distinguishing purpose is dedicated music generation rather than general video or text tasks, and it splits from its own Clip sibling by producing complete songs instead of short segments. Ideal for content creators and marketers who need original, ready-to-use music without a composer or licensing overhead. Pick it when you want full tracks at a fixed low per-song rate; choose the Clip variant instead if you only need brief snippets, and look elsewhere if your work depends on tool calling.
