Tencent Dropped Hy4 Preview and its ACTUALLY GOOD!?

#TencentHY4 #HY4 #OpenSourceAI China is on freaking fire these past few months!! While everyone is focused on GPT Astra, Fable 5.1, Claude, and the next wave of unreleased frontier models, Tencent has already released HY4 Preview — and some of the coding, game development, agentic workflows, and 3D demos people are creating with this model are ridiculous. In this video, I’m breaking down Tencent HY4, its huge 770B-parameter Mixture-of-Experts architecture, 49B active parameters, 1M-token context window, open weights, coding capabilities, WorkBuddy integration, and some of the best real-world HY4 demos I could find. More importantly, we’ll look at whether HY4 can actually compete with models like Kimi K3, GLM 5.3, Qwen, DeepSeek, and other leading coding models — because this thing is getting way less attention than it deserves. 0:00 — Stop Sleeping on HY4 0:57 — What HY4 Actually Is 1:59 — The Playable Game Demos 2:39 — The Tactical Shooter 3:23 — Look Past the First Frame 4:07 — Where Other Models Still Win 4:51 — The Real Advantage Is Memory 5:45 — This Is Bigger Than Coding 6:33 — Accessibility and the Catch 7:44 — My Verdict 📌 OFFICIAL TENCENT HY4 LINKS Official Tencent Hunyuan HY4 launch https://x.com/TencentHunyuan/status/2093222928720761009 Official Website Drop https://hy.tencent.ai/research/hy4-preview Tencent Hunyuan — additional HY4 information/demo https://x.com/TencentHunyuan/status/2093572224342954019 Arena / HY4 model discussion https://x.com/arena/status/2093224696745492802 🎮 HY4 PLAYABLE GAME DEMOS HY4 playable game demo #1 https://x.com/eyishazyer/status/2094489426865037497 HY4 playable game demo #2 https://x.com/eyishazyer/status/2094489444103639055 HY4 playable game demo #3 https://x.com/eyishazyer/status/2094489447954018535 Kunal Jain — HY4 Tactical FPS https://x.com/Kunal_Jain9/status/2094373664548704629 Play the Last Light Tactical FPS https://kunaljain.app/lab/last-light-tactical-fps HY4 game demo — RealFedeURU https://x.com/RealFedeURU/status/2094443534958903767 Additional HY4 game demo https://x.com/RealFedeURU/status/2094164940152021176 Fabiano Firmo — HY4 demo https://x.com/FabianoFirmo/status/2093284279467807156 ⚔️ HY4 SIDE-BY-SIDE COMPARISONS HY4 comparison https://x.com/0x0SojalSec/status/2094547435855224985 HY4 side-by-side comparison https://x.com/Haleeeemahh/status/2093436935532331204 Additional HY4 comparison https://x.com/Haleeeemahh/status/2094350696237629794 HY4 model comparison https://x.com/aipulseda1ly/status/2094549105204703628 Additional HY4 testing https://x.com/notjazii/status/2093370340064047143 HY4 model/demo results https://x.com/UddipanBarman/status/2093369424007029215 HY4 testing / comparison https://x.com/noclipepe/status/2093278425049895409 🧑‍💻 HY4 WORKBUDDY / OFFICE AGENT DEMOS HY4 + WorkBuddy demo https://x.com/jRMCC3x6jb96459/status/2094649116571942957 WorkBuddy / HY4 productivity demo https://x.com/Punkstore333/status/2094615195951993210 HY4 office-agent workflow https://x.com/n5waha/status/2094302969290449230 HY4 WorkBuddy example https://x.com/kibubble_de/status/2094380422750765484 📺 ADDITIONAL HY4 COVERAGE Julian Goldie — HY4 https://x.com/JulianGoldieSEO/status/2094604724834336994 Brendan Jowett — HY4 https://x.com/jowettbrendan/status/2094340076373446747 Additional HY4 coverage https://x.com/jowettbrendan/status/2094340220489699584 HY4 recap https://x.com/mr_mmon/status/2094652399873134888 🔥 IN THIS VIDEO • What is Tencent HY4? • Why HY4 is going under the radar • 770B total parameters • 49B active parameters • 1M-token context window • HY4 coding performance • HY4 game development • Playable 3D game demos • Tactical FPS generation • Long-horizon coding and agent workflows • HY4 vs GLM • HY4 vs Qwen • HY4 vs Kimi K3 • HY4 vs DeepSeek • WorkBuddy + HY4 • Office and productivity agents • Open-weight AI models • Is Tencent HY4 worth using? ⚠️ NOTE: Some demonstrations shown in this video were created and shared by third-party users.
