Chinese AI Models Gain Ground with U.S. Companies as Cost Gap Widens

Jul 7, 2026

U.S. companies are increasingly adopting Chinese AI models from firms like DeepSeek and Z.ai, driven by costs 60-90% lower than U.S. rivals OpenAI and Anthropic. The performance gap has narrowed to just 6-9 months, prompting startups like Lindy to switch entirely and save millions. This trend, facilitated by open-source models, has led the U.S. government to consider new regulations on powerful AI and foreign alternatives.

Chinese AI model adoption

▪On the platform OpenRouter, Chinese AI models have accounted for over 30% of traffic each week since February 8.
▪In its first week on the Vercel platform, Z.ai's GLM 5.2 model saw its daily token volume grow about 27x and its customer base grow about 80x.
▪AI startup Lindy moved 100% of its traffic from Anthropic's Claude models to a model from the Chinese company DeepSeek.
▪The average share of traffic for Chinese models on OpenRouter was 11% across the previous 12 months.

Cost advantages over U.S. models

▪Lindy CEO Flo Crivello said the company's switch to DeepSeek will save it millions of dollars within months.
▪According to OpenRouter employee Justin Summerville, Chinese open-source models can be 60% to 90% cheaper than leading models from OpenAI and Anthropic.
▪Rising token prices for advanced models from U.S. AI labs are causing American companies to become more cost-conscious.

Performance gap narrowing

▪Z.ai's GLM 5.2 model performed within one percentage point of Anthropic's Opus 4.8 on an agentic benchmark, at roughly one-fifth of the cost.
▪The Brookings Institution's Kyle Chan estimates Chinese AI models are six to nine months behind top U.S. rivals in performance.
▪A May report from the Center for AI Standards and Innovation (CAISI) found Chinese AI models trail leading U.S. models by about eight months.

U.S. regulatory response

▪The U.S. administration is considering regulations for its most powerful AI models and ways to halt the adoption of overseas alternatives.
▪In late June, OpenAI stated it would limit the rollout of a new set of models at the U.S. government's request.

Open-source model strategy

▪Open-source and open-weight models, many of which are from Chinese companies, make parts of an AI model available for developers to use and modify.
▪Open models contrast with closed, proprietary systems from companies like OpenAI, Anthropic, and Google.
