DeepSeek, a Chinese AI startup, has emerged as the most popular AI tool among US businesses, according to BeInCrypto. The company topped Ramp's June trending vendor index, which tracks payments from over 50,000 US businesses. DeepSeek's competitive pricing, including a 75% cut on its V4 Pro model, has attracted cost-conscious firms away from US rivals like Anthropic and OpenAI. Despite concerns over data being sent to China, DeepSeek's appeal grows as US companies seek affordable alternatives amid tightening AI budgets.
