In this video, I fully test DeepSeek V4 Pro (0813) to see if it’s actually the best open-source AI model available right now. We put it through frontend development, agentic coding, 3D/Three.js, one-shot generation, and real-world coding workflows. 💻🔥 🚨 Everything you’re about to see, I benchmarked using the tool I made. If you want to run these tests yourself or test models on whatever you actually use them for! → https://www.woaibench.ai/ 🔗 My Links: Sponsor a Video or Do a Demo of Your Product, Contact me: [email protected] 🔥 Become a Patron (Private Discord): https://patreon.com/WorldofAi 🧠 Follow me on Twitter: https://twitter.com/intheworldofai 🚨 Subscribe To The SECOND Channel: https://www.youtube.com/@UCYwLV1gDwzGbg7jXQ52bVnQ 👩🏻‍🏫 Learn to code with Scrimba – from fullstack to AI https://scrimba.com/?via=worldofai (20% OFF) 🚨 Subscribe To The FREE AI Newsletter For Regular AI Updates: https://intheworldofai.com/ 👾 Join the World of AI Discord! : https://discord.gg/NPf8FCn4cD Something coming soon :) https://www.skool.com/worldofai-automation [Must Watch]: OpenAI's GPT-6 Astra WILL BE AGI!

One of the biggest highlights is its price-to-performance. DeepSeek remains incredibly cheap for the level of coding and agentic capability you’re getting, especially when combined with a powerful agent harness. 🐋 DeepSeek V4 Pro (0813) full testing 💻 Agentic coding & frontend tests 🎮 One-shot coding tests 🌐 Three.js & 3D generation ⚡ V4 Pro vs V4 Flash 🆚 Gemini, Grok, Kimi, GLM & Qwen comparisons 🤖 DeepSeek Harness + V4 Pro 💰 Cost, speed & quality comparisons 📊 Final verdict: Is V4 Pro the best open-source AI model?
