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.

Nicelydone MCP is a Model Context Protocol server that gives AI coding agents access to over 140,000 real screens, user flows, and UI components from shipped consumer and B2B products. When an agent is building an interface, it can pull authentic reference designs matching the target use case instead of generating generic layouts from training data alone. The server integrates with Claude, Cursor, VS Code, and any MCP-compatible client. Designers and developers can query the library by UI pattern type (empty states, onboarding flows, settings pages, etc.) and the agent incorporates those real-world examples as visual context. The core insight is that AI models trained on internet data produce 'average' interfaces — they know what UI elements exist but not which combinations are actually good. Nicelydone injects a curated signal of real quality product design into the generation process, addressing one of the most consistent weaknesses in AI-generated frontends.
Reviewer scorecard
“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.”
“Anyone who's tried to get Claude or GPT to generate a non-hideous onboarding flow knows the pain. Plugging in 140k real UI patterns as context is the right fix — you're giving the model a design vocabulary instead of hoping it learned one. Shipped three features this week with notably better first-pass UI quality.”
“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.”
“Reference design libraries are only as good as their licensing. It's unclear whether Nicelydone has rights to use all 140k screens commercially, and using an MCP server built on potentially scraped UI assets could expose teams to legal risk. Verify the terms before integrating into client work.”
“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.”
“This is a preview of how design systems will work in an agent-first world — not static Figma files but queryable knowledge bases that agents can pull from at generation time. Nicelydone's approach could evolve into industry-standard design context infrastructure, the way npm became infrastructure for code.”
“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.”
“As a designer this is genuinely exciting. I can now describe a pattern ('progressive disclosure pricing table with annual toggle') and the agent pulls a real example from a product people actually use, then implements from that reference. It's like giving the AI a proper inspiration board before it starts designing.”
