Tiny Toybox Pages

Open the playable Fire Boy pet room, inspect the rig, and review the evidence trail behind the Modal, MiniCPM, VLA, and Codex-assisted build.

Demo story

Fire Boy is a tiny model-backed toy with a real build trail.

Toy Room v3 routes typed or spoken commands through a bounded PET action contract, then turns model output into speech, animation, physics, camera traces, and room objects.

Modal is used for serverless MiniCPM-o inference, while the VLA path keeps MiniCPM-V 4.6, policy heads, and RunPod rollout artifacts visible as training proof instead of hidden notes.

Modal runtimeWarm serverless gateway for MiniCPM-o action turns and token/latency traces.
VLA trainingMiniCPM-V 4.6 scaffolds, LoRA/action-head checkpoints, and MP4 eval proof.
Codex commitsRepo history shows Codex-assisted implementation and docs across v3, Modal, VLA, and diagnostics.

The point of the demo is visible causality: model call, action contract, embodied result, and training evidence are all inspectable.
