BEIJING: A version of Chinese startup DeepSeek’s flagship artificial intelligence (AI) model is by far the least expensive to run on benchmark tests among well-known models globally and more than 100 times cheaper to run than Anthropic’s Claude Fable 5, according to a research firm.
DeepSeek, which sources have said is preparing for a potential initial public offering, officially released its V4-Flash model last Friday, its latest attempt to regain momentum by doing what it is best known for – offering ultra-low-cost AI alternatives.
The startup’s R1 model became a global sensation in early 2025, triggering a sell-off in global technology stocks and raising questions about the large amounts US companies were spending on AI.
DeepSeek’s V4-Flash charges 14 US cents per million input tokens and 28 US cents per million output tokens, according to research firm Artificial Analysis. A token is a unit of data used to measure AI usage.
San Francisco-based Artificial Analysis estimated V4-Flash’s average cost at three US cents per test, compared with 86 cents for Kimi K3 from Chinese rival Moonshot AI, US$1.86 for OpenAI’s GPT-5.6 Sol and US$3.15 for Claude Fable 5.
The comparison provides a more realistic measure of value than pricing alone because it accounts for the amount of data a model must process and generate to complete a task.
A model with low headline price can still prove expensive if it requires significantly more steps to produce an answer.
DeepSeek once commanded most of the headlines about Chinese AI development, but was quickly besieged by many domestic rivals, including other startups such as Moonshot, MiniMax and Z.AI as well as tech giants like ByteDance and Alibaba.
All are vying with US tech firms for global adoption, targeting businesses seeking cheaper ways to deploy AI at scale.
Artificial Analysis said DeepSeek’s V4-Flash model scored 50 out of 100 on its Intelligence Index, which combines results from nine benchmarks spanning coding, reasoning and workplace-style assignments.
That’s the same score as Google’s Gemini 3.6 Flash, and one point behind Meta’s Muse Spark 1.1 and GLM-5.2 from Z.AI, which is also known as Zhipu.
Moonshot’s Kimi K3, however, scored a 57, while Anthropic’s Claude Opus 5, Fable 5, and OpenAI GPT-5.6 scored nine or more points higher.
DeepSeek is also preparing a more powerful version of its model, called the V4-Pro. It has not given a date for that version’s official release.
Separately yesterday, Alibaba unveiled its largest and most capable AI model to date, the Qwen3.8-Max, which is not far behind in size when compared with an offering from domestic rival Moonshot AI launched last month. — Reuters
