Deepseek v4: Best Opensource Model Ever? (Fully Tested)

DeepSeek is BACK with the V4 release… but is it actually the best open-source model ever? In this video, I put DeepSeek V4 Pro and DeepSeek V4 Flash to the test — from coding, agentic workflows, and long-context tasks, to real-world generation like building apps, animations, and even a Minecraft clone. 🔗 My Links: Sponsor a Video or Do a Demo of Your Product, Contact me: intheworldzofai@gmail.com 🔥 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]: Claude Code + Ollama = FULLY FREE AI Coding FOREVER!

I break down: Real-world coding performance (not just benchmarks) Arena rankings vs Kimi K2.6 & GLM 5.1 Agentic workflow capabilities Long-context performance Cost vs quality tradeoffs Where it actually shines… and where it falls apart Spoiler: this might be one of the most efficient models we’ve seen… but that doesn’t mean it’s the best. 🔥 Key Takeaways • 1M context is
