I am working on GridLockd, a synthetic, multi-view benchmark designed to test whether vision-language models can maintain a unified, consistent 3D world model over time.

A Benchmark for Testing Whether AI Truly Understands a 3D World
GridLockd challenges a major assumption in today’s VLM and robotics evaluation frameworks: that strong performance on isolated perception tasks—like object counting, short-term physics, or spatial reasoning—implies the model has a genuine internal “world model.” Instead of testing components in isolation, GridLockd asks a more fundamental question: can a model maintain a single, unified 3D representation as the scene changes, the viewpoint moves, and objects become occluded or reappear? Unlike typical single-image, multiple-choice benchmarks, GridLockd uses a synthetic, spatio-temporal environment where a game engine records full world metadata, allowing precise, continuous evaluation of a model’s internal reasoning. To measure this, the benchmark introduces eight diagnostic metrics—such as identity persistence, multi-view fusion, causal world simulation, and long-horizon prediction—that reveal how a model’s internal representation breaks down. GridLockd’s procedural generation pipeline also solves a long-standing issue in VLM testing: shortcuts. Many models exploit texture or color correlations instead of understanding true physics. By separating visual appearance from physical dynamics, GridLockd can identify when a model depends on these superficial cues. Its Generalized Domain Deviation Index (GDDI) quantifies how performance shifts under style changes, exposing brittleness and entanglement failures that traditional benchmarks miss. Finally, GridLockd differs sharply from embodied-agent benchmarks that evaluate end-to-end task success. Those frameworks mostly measure policy optimization—whether an agent completes a goal—which entangles action quality with perception quality. GridLockd isolates the representational core: does the model maintain a coherent latent world state and accurately predict how it evolves over time? By comparing uninformed baselines, classic dynamical models, single-view models, and multi-view fine-tuning approaches, the benchmark disentangles pattern-matching from genuine 3D reasoning. Instead of a leaderboard, it provides a diagnostic map to guide the development of next-generation models capable of robust, spatio-temporal world understanding.
Creating interaction that feels intuitive, considered, and emotionally aligned:
When motion, structure, and design align, users don’t think—they feel. That’s the sweet spot where layout becomes a bridge. Interfaces should communicate tone as much as task. Even the simplest detail—a button’s curve or a heading’s weight—can influence how someone feels. Modular components give structure, but it’s the unexpected breaks—the asymmetry, the shift in rhythm, the quiet gesture—that introduce character. That’s where emotion sneaks in. That’s where the layout becomes a story, not just a scaffold. It’s in the relationship between repetition and surprise, clarity and contrast, that visual tension thrives. We often think of layouts as fixed, but the best ones are elastic. They stretch to fit diverse narratives, but never lose coherence. They allow variation without losing voice. When a layout becomes too stiff, it feels soulless. When it becomes too loose, it loses trust. The sweet spot lies in the in-between. That edge—that living edge—is where the work breathes.

Balancing order and creativity for expressive user interfaces:
They aren’t rigid templates or chaotic experiments—they’re frameworks that breathe, adapt, and respond. A layout, when designed with intent, doesn’t just hold content—it elevates it. It becomes the unseen rhythm of the page, guiding the user’s eye with balance, restraint, and just enough tension to keep things alive. A smart layout doesn’t impose itself. It listens. It bends where it needs to. It adjusts for type, for image, for tone. It creates systems that can scale but still feel personal. A great layout doesn’t flatten expression—it preserves soul. It knows when to hold back and when to surprise. That balance is the mark of a thoughtful designer. Find more insights on Akihiko Blogs.
