DeepSeek Releases V4.1-Flash-1017 with 77.0 DeepSWE Score and Opens Search API

DeepSeek has shipped V4.1-Flash-1017, a new flash-tier model iteration scoring 77.0 on the DeepSWE benchmark, a coding and software-engineering evaluation that directly measures real-world developer utility. Alongside the model, DeepSeek is opening its Search API, giving developers programmatic access to web-grounded retrieval integrated with model inference. The DeepSWE score of 77.0 places it competitively among frontier coding models and signals DeepSeek's continued aggressive iteration cadence. For developers building coding assistants, agentic pipelines, or retrieval-augmented applications, the newly available Search API is an immediately actionable integration point. This release continues the pattern of DeepSeek shipping high-capability, cost-efficient models that challenge Western lab offerings on performance-per-cost metrics.
