Chinese AI Models Surge Past 30% U.S. Market Share as Cost Savings Drive Businesses Away from OpenAI and Anthropic

Chinese AI models like DeepSeek are surging past 30% U.S. market share as businesses abandon OpenAI and Anthropic for alternatives that are up to 90% cheaper and rapidly closing the performance gap with American frontier models.

• Chinese AI models from companies like DeepSeek and Z.ai are rapidly gaining adoption among U.S. businesses, with their share of tokens used via OpenRouter surging above 30% weekly since February, up from an average of just 11% over the prior 12 months.
• Cost is a major driver of the shift, as Chinese open-source models are 60% to 90% cheaper than leading U.S. models from OpenAI and Anthropic, prompting companies like AI startup Lindy to fully switch to DeepSeek, saving millions of dollars.
• Chinese models are closing the performance gap with top U.S. systems, estimated to be only six to nine months behind frontier American models, raising concerns that businesses may be forced to choose between expensive U.S. proprietary models or Chinese alternatives to control costs.
