Google has upgraded Lyria 3 to Lyria 3 Pro — a significant step up in its music generation model that's now available across Vertex AI, Google AI Studio, the Gemini API, Google Vids, and the Gemini app. The key jump: the new model generates tracks up to three full minutes (vs. the previous 30-second cap), with structured song sections including intros, verses, choruses, and bridges that actually transition musically. The model adds multilingual vocals (sing in any of 140+ supported languages), JSON-structured prompting for reliable format control, and maintains Google's SynthID watermarking on all output for provenance tracking. Audio quality has been noticeably improved, with better instrument separation and more natural dynamics across the full track length. For developers, Lyria 3 Pro is available via the standard Gemini API — the same authentication and SDK you'd use for text generation, which dramatically lowers the barrier to integrating music into apps. Google Vids gets native integration, making AI-scored video content a one-click operation.

Marble 1.1 and 1.1 Plus are the latest updates to World Labs' generative 3D world model, the flagship product from the spatial AI startup co-founded by Fei-Fei Li. The 1.1 release focuses on visual quality improvements: better lighting and contrast handling, reduction in common visual artifacts (flickering, geometry drift at scene edges), and more consistent object coherence across viewing angles. Marble 1.1 Plus introduces dynamic scale — the model's most significant capability expansion since launch. Previous generations produced worlds of fixed spatial extent; 1.1 Plus automatically analyzes scene complexity and expands world coverage by deploying up to five "dynamic cubes" in a single generation pass. The result is environments that fill out naturally across a larger footprint without requiring multiple generation runs or manual stitching. Target use cases include game environment prototyping, architectural visualization, and training data generation for robotics simulators. World Labs has positioned Marble as the world's first commercially available spatial intelligence product, and the 1.1 updates shipped April 7-8, 2026 via the marble.worldlabs.ai web app. The dynamic scale feature in 1.1 Plus is available on paid plans, while quality improvements in 1.1 apply across all tiers. The updates arrive as competition in AI 3D generation heats up from tools like Luma AI and TripoSG.
Reviewer scorecard
“Same API key as Gemini, three-minute output, JSON prompting for structure — this is finally production-ready for apps that need dynamic background music or scored video. The integration with Google Vids is a smart forcing function.”
“Dynamic scale in a single generation pass is the feature I've been waiting for. Having to stitch multiple fixed-extent generations together was the main workflow pain in Marble 1.0 for game environment prototyping. If 1.1 Plus delivers on the demo quality, it cuts 3D world prototyping time by an order of magnitude.”
“Three minutes is still too short for most real-world music use cases, and 'structured sections' often still sound jarring compared to human-arranged music. Suno and Udio are ahead on pure output quality; Lyria's advantage is ecosystem integration, not sound.”
“The demos are impressive but the generation-to-game-engine pipeline is still manual and lossy. You can't export clean meshes with proper LODs or collision geometry — it's a concept tool, not a production asset pipeline. Until you can import Marble output directly into Unity or Unreal with proper metadata, this stays in the 'cool demo' category for most game devs.”
“The integration path is the story here: music generation directly inside the same developer stack as text and video means personalized, dynamic audio becomes a default feature of AI apps, not a special case. That's a massive shift for UX design.”
“Fei-Fei Li's bet that 3D spatial intelligence is the next fundamental modality is looking more plausible with each Marble update. Dynamic world generation at scale is a prerequisite for training embodied AI agents — Marble's real customer may be the robotics and simulation market, not game studios.”
“Three minutes of structured music that transitions properly is the minimum bar for real creative use. Lyria 3 Pro finally clears it. I'd use this for short film scoring and social video — it's not replacing a composer, but it's replacing stock music licensing.”
“For concept artists and production designers, Marble 1.1 is a rapid ideation tool that works. Generating a believable environment in 60 seconds to show a client a mood and spatial feel — even as a rough 3D sketch — beats days of modeling. The dynamic scale expansion is exactly what cinematic environment work needs.”
