> RL visualization dashboard for the Tinker API

Published: 2026/02/01 • Author: Surya Dantuluri • Canonical: https://sdan.net/projects/tviz

A dashboard for RL training runs — similar to Weights & Biases but natively built for the Tinker API to review and replay text and vision trajectories. Supports logprobs visualization and Qwen3-VL specific features.

Inspired by the Tinker console, tviz lets you scrub through training episodes frame-by-frame and see exactly what the model saw, thought, and decided at each step.
