Claude Opus 4.7 Dominates Design Arena's Slides Category

It has come to light that Anthropic's latest flagship "Claude Opus 4.7" and its extended-thinking version "Opus 4.7 (Thinking)" lead the Slides (slide generation) category of the AI design evaluation platform Design Arena by a wide margin, holding a lead of more than 80 Elo points over the second-place and lower models.1

What Happened

On Design Arena's Slides leaderboard, Claude Opus 4.7 and Claude Opus 4.7 (Thinking) (@AnthropicAI) occupy the top spots, holding a lead of more than 80 Elo points over trailing models such as GLM 5.1, Gemini 3.5 Flash, and Kimi K2.6.1

Design Arena is a crowdsourced benchmark that compares each model's outputs to the same prompt via user voting and computes ratings using the Elo method. In the Slides category, the quality of slide generation is the subject of evaluation.7

The underlying Claude Opus 4.7 is the flagship model for which Anthropic began general availability (GA) on April 16, 2026, with the API model ID claude-opus-4-7. Pricing is $5 input / $25 output per 1 million tokens, and the context window is said to be 1M tokens.2

Background and Significance

Anthropic positions Opus 4.7 as able to generate "higher-quality interfaces, slides, and documents." What is driving up slide generation quality in particular is high-resolution vision: the long edge of image inputs reaches up to 2,576 pixels (about 3.75 megapixels, more than triple the previous figure), improving the accuracy of recognizing fine details in text and diagrams.2
