World Model Optimizer
A CLI from Experiential Labs that turns collected agent traces into smaller models you own. wmo optimize distills frontier behaviour via the Tinker API, and wmo serve routes requests between frontier and small models — reported at frontier-level quality for 27% less cost on RouterBench.
✅ Pros / Advantages
- • Turns a wasted asset (traces) into an owned model
- • Honest held-out reporting built into the workflow
- • Routing and distillation in one tool
- • Simulation environment for closed-loop testing
- • Broad provider support
- • Hosted option if you don't want to run it
❌ Cons / Limitations
- • No license file declared, which matters for commercial use
- • Depends on the Tinker API
- • Needs meaningful trace volume before it works
- • The 27% figure is the vendor's own RouterBench result
- • Young project with a high open-issue count

ModelMap
ModelMap (modelmap.tech) is an interactive 3D visualization that turns AI model benchmark scores into explorable shapes. Each model's performance across public benchmarks is rendered as a 'spiky' 3D form — longer spikes mean higher scores — parsed live from Hugging Face model cards. Built on an open-source '3D Graph' library, it offers a flight-simulator-style interface (WASD to fly, mouse to look, click a spike to zoom, hover for tooltips) for browsing model data in space rather than static tables. A hidden Star Wars-themed mini-game underscores its goal of making model analysis more playful. It's a free, browser-based research toy — novel for building intuition, though it has drawn technical criticism on how it represents scores.
