Anthropic on Wednesday said its artificial intelligence chatbot Claude will remain ad-free, a decision that comes just weeks after the startup's rival OpenAI announced plans to begin testing advertisements within ChatGPT.
In a blog post, Anthropic said that Claude users will not see ads or sponsored links near their conversations, and the chatbot's answers will not be influenced by third-party product placements.
The personal nature of users' conversations with Claude would make ads feel "incongruous" and "in many cases, inappropriate," the company said.
Anthropic was founded in 2021 by former OpenAI researchers, including its CEO, Dario Amodei. The company is best known for developing a family of AI models called Claude, and its AI coding tool Claude Code has exploded in popularity in recent months.
"Our business model is straightforward: we generate revenue through enterprise contracts and paid subscriptions, and we reinvest that revenue into improving Claude for our users," Anthropic said in the blog post. "This is a choice with tradeoffs, and we respect that other AI companies might reasonably reach different conclusions."
