Union Alpha: A Free Model Just Beat Opus 5/GPT-Sol
In this video, we run an in-depth benchmark and stress-test on the stealth "Union Alpha" model across complex real-world agentic coding tasks. From building real-time interactive Three.js/WebGL physics simulations (Black Hole accretion disk) to procedural 3D voxel scenes and game engines, we evaluate how this lightweight active-parameter architecture stacks up against frontier models like Claude Opus 5 and GPT-6 Astra. 📌 What We Cover: • DeepSWE agentic benchmark & task pass rates • Multi-turn tool execution & cache efficiency (up to 79% cache hit) • Three.js WebGL real-time simulation generation • Architectural deep dive: Causal encoder/decoder & sparse attention • Full token cost and speed breakdown LINKS: https://openrouter.ai/stealth/union-alpha#providers My voice to text App: whryte.com Website: https://engineerprompt.ai/ RAG Beyond Basics Course: https://prompt-s-site.thinkific.com/courses/rag Signup for Newsletter, localgpt: https://tally.so/r/3y9bb0 💻 Pre-configured localGPT VM: https://bit.ly/localGPT (use Code: PromptEngineering for 50% off).
