DeepSeek推出的4.1 Flash模型在性能与成本方面展现出显著优势，但这一进展似乎未获得业界应有的关注。1根据使用者的一个月体验，该模型的性能可与Anthropic和OpenAI的顶级模型相当，但价格远低于后者。1
在技术优化上，DeepSeek 4.1 Flash相比V1版本大幅提升了资源效率。1其KV缓存相比V1版本缩小了437倍，这一优化使得模型能够以更低的计算成本运行。1用户通过OpenCode Go订阅（月费10美元）可基本实现DeepSeek的无限使用，单个编程会话的成本通常不超过1美元，与Claude等竞品的高成本相比优势明显。1根据该模型使用者的观点，这种成本差异应该改变行业的工作方式和开发习惯，但目前这一潜力尚未被充分认识。1
DeepSeek's latest model, version 4.1 Flash, delivers performance comparable to leading alternatives from Anthropic and OpenAI while operating at a fraction of the cost, according to a developer who has used the system for over a month 1. The model achieves significant efficiency gains through optimized KV cache architecture, which is 437 times smaller than the previous version 1, enabling substantially faster and less resource-intensive operations.
The cost advantages are particularly striking for practical applications. Through an OpenCode Go subscription priced at $10 monthly, users gain essentially unlimited access to DeepSeek 1, with individual programming sessions typically costing less than $1 1—dramatically lower than comparable usage on competing platforms. The performance differential between DeepSeek 4.1 Flash and premium alternatives like Claude Opus is nearly imperceptible in practical use 1. Despite these capabilities and economics, the developer argues that the broader industry has failed to recognize how these improvements could reshape development workflows and practices 1.
