GPT-5.6 Family Tested and Compared
WorldofAI · youtube · 2026-07-10
This World of AI video conducts comprehensive tests on the GPT-5.6 family, specifically comparing Sol / Terra / Luna against Claude Fable 5, Grok 4.5, and GLM 5.2 in coding, frontend generation, agent workflows, 3D web apps, and real-world tasks.
The video covers multiple benchmarks and practical tests, including Artificial Analysis, OSWorld, Terminal-Bench, as well as:
- Coding and agentic AI performance
- Frontend / UI generation
- Three.js and Minecraft clone demos
- Cost, speed, and token efficiency comparisons
- An explanation of "Ultra Mode"
The creator concludes that OpenAI's new model lineup is highly competitive across multiple dimensions, raising questions: could Sol replace Claude, is Terra the ultimate value-for-money model, and is Luna the best lightweight model?
