WorldofAI · youtube · 2026-09-23
Anthropic has shipped Claude Opus 5.5, a faster and more per-task-efficient upgrade over Opus 5. YouTuber WorldofAI ran it through his own benchmark tool (woaibench.ai) across agentic coding, complex frontend work, visual design, and game generation.
Highlights:
- One-shot game development, complex 3D scenes, and SVG design tasks
- Head-to-head comparisons with Claude Fable 5.1 and GPT-6 Astra
- Verdict: richer environments, stronger attention to detail, better visual composition, and more polished outputs
Whether it's the greatest model yet is left for viewers to judge; the full testing walkthrough is in the video.
