Enterprises prefer Anthropic’s AI models over anyone else’s, including OpenAI’s
Anthropic's AI models have surged to become the top choice among enterprises, capturing 32% of the large language model market by usage, overtaking OpenAI, which has fallen to 25%. This shift reflects a significant change from two years ago when OpenAI led with a 50% share. Anthropic's recent model releases, particularly Claude 3.5 and 3.7 Sonnet, fueled this growth, while enterprises increasingly prefer closed models over open source.
