DeepSeek V4 Is Earning Agentic Token Share

DeepSeek's release of its new V4 model in April 2026 has significantly increased its share in the competitive landscape of large language models (LLMs), particularly in agentic workloads, where it has become a favored choice due to its cost-effectiveness. Initially holding under 10% of token flow across OpenRouter, DeepSeek's share fell to 5% as proprietary and other open-source models gained traction earlier in the year; however, by June, it had captured nearly 20% of the market. The V4 model, offering affordability with a price of $0.09 for input and $0.18 for output per million tokens compared to GPT-5.5's $5 and $30 respectively, has been instrumental in this growth. This shift reflects broader trends in the market, where Chinese models, including DeepSeek, have gained prominence, surpassing American models in token share by June 2026. The increase in agentic workload token usage, which is significantly higher than human AI usage, is a 2026 phenomenon, and DeepSeek's V4 has positioned the company as a leader in this segment. The data, sourced from OpenRouter's request logs, highlights a dynamic shift in preferences as organizations seek to balance cost and performance by integrating diverse AI models.
