Claude Opus 4.7 Takes the Top Spots in Slide Generation

Anthropic's "Claude Opus 4.7" and "Claude Opus 4.7 (Thinking)" have taken the No. 1 and No. 2 spots in the Slides category of "Design Arena," a crowdsourced benchmark that evaluates AI-generated design, pulling ahead of other models by more than 80 Elo, as revealed in an official X post by the operator (June 1, 2026). 1

What Happened

According to a post by the Design Arena official account (@Designarena), in the Slides category Anthropic's two models lead other models by more than 80 points in Elo rating, establishing a de facto standard for slide generation. Following from third place are Z.ai's "GLM 5.1," Google DeepMind's "Gemini 3.5 Flash," and Moonshot's "Kimi K2.6." 1

Design Arena is a platform where users vote on side-by-side generation results from multiple models for the same prompt, updating rankings via an Elo system. The Slides category targets "Agentic Slides" (autonomous slide generation and editing) for evaluation, focusing on PowerPoint-style PPTX output and presentation material generation. 2

Background and Significance

Design Arena bills itself as "the world's first crowdsourced benchmark for AI-generated design," operated by The Intelligence Company / Arcada Labs, and has multiple categories including UI/Website, Image, 3D, Code, and Slides. The Slides Arena was revived around March 2026, and dedicated tools such as Gamma, Alai, and Manus also participate. 3

Anthropic added "Claude Opus 4.7" to Design Arena around April 16, 2026. The following day, on the 17th, it released a new product based on the Opus 4.7 foundation model, "Claude Design" (Anthropic Labs), as a research preview. It is a tool that can conversationally generate and edit prototypes, slides, and one-pagers from text prompts, screenshots, and existing PPTX/DOCX files, and Anthropic positions the model as "best for visual work (design, prototypes, slides)." 4
