Anthropic's Claude AI assistant and coding tools, Claude, has become the most popular iPhone app in Apple’s iPhone App Store after a flurry of events in February, including a public feud with the Pentagon over its safety guardrails. The company's Claude app dethroned OpenAI’�s ChatGPT to take the top spot in Apple's iPhone App store over the weekend. The increased visibility comes as Anthropic has been locked in a high-stakes public feud over the Pentagon's safety guardrail. Despite this, Anthropic still has a long way to go to catch up to ChatGTT in public popularity. The rise in popularity could signal an inflection point for the company, as OpenAI CEO Sam Altman acknowledged some potential violations of their contract with the military regarding Anthropic's AI system.
