minuzero/VideoKR-Qwen3-VL-8B API & Inference Endpoint

About

This repository contains the VideoKR-Qwen3-VL-8B model presented in VideoKR: Towards Knowledge- and Reasoning-Intensive Video Understanding (ICML 2026 Spotlight).

VideoKR-Qwen3-VL-8B is obtained through a standard SFT → GRPO pipeline on Qwen3-VL-8B-Instruct:

Supervised fine-tuning on VideoKR-SFT-201K with CoT rationales → VideoKR-Qwen3-VL-8B-SFT
GRPO reinforcement learning on VideoKR-RL-114K with verifiable rewards → this model

VideoKR is the first large-scale training corpus designed for knowledge- and reasoning-intensive video understanding, containing 315K video reasoning examples over 145K newly collected, CC-licensed expert-domain videos across 82 professional subjects.
