New research from Profound revealed significant differences in web search behavior and response characteristics between the Claude and Claude Code artificial intelligence models, despite their shared underlying technology.

The study indicated these distinct patterns could necessitate separate measurement and optimization strategies for brands aiming to engage with users through various AI models.

Claude utilized web search in 93 percent of its responses, while Claude Code accessed web search in only 13 percent of its responses, according to the Profound analysis.

Brand mentions for identical prompts overlapped by approximately 20 percent between the two models, suggesting varying approaches to information retrieval and presentation.

Profound reported that Claude Code’s responses were notably shorter, averaging 322 words compared to Claude’s 459 words.

More than half of Claude Code’s responses included a table, indicating a more structured and concise output format.

Claude Code’s agent primarily visited documentation, informational, and pricing pages, which accounted for nearly 75 percent of its page visits.

In contrast, Claude’s agent focused on robots.txt files, sitemaps, and homepages, comprising 60 percent of its web activity.

For coding-specific prompts, Claude tended to reference code editors, while Claude Code showed a preference for code-quality and workflow tools.

The findings highlight that even AI models built on similar foundations can develop unique operational tendencies, impacting how they interact with web content and present information to users, according to Profound.

Organizations like Cast Of Thousands/Shutterstock, which provided imagery for the report, underscore the broader ecosystem surrounding AI development and analysis.

The research suggests that brands and developers should consider these behavioral discrepancies when designing content strategies and optimizing for visibility across different AI platforms.
