Tencent's Hunyuan lab is one of the most prolific open-weights media teams we cover, spanning 3D generation, video, avatars, OCR and portrait models. ThursdAI — the weekly AI news podcast hosted by Alex Volkov — has covered 17 Tencent releases since Jan 2025, most recently Hunyuan3D WorldClaw on Aug 13, 2026. Highlights include Hunyuan 3D 2.5, HunyuanOCR, Hunyuan-A13B-Instruct, Hunyuan3D 2.0. 12 of them shipped with open weights. Every entry below has the episode segment where we covered it live, plus primary-source links and key numbers where we have them.
