DeepSeek: DeepSeek V4 Flash
Analysis Summary
DeepSeek V4 Flash is a DeepSeek model released in April 2026, with a 1,048,576-token context window and support for tool use and function calling. Its coding index is 69.1 and agentic index is 41.0. The data also shows strong instruction following and long-context performance, so it can handle substantial inputs while supporting structured, multi-step tasks.
This profile fits code assistance, repository analysis, document-heavy work, and agent workflows where the model needs to call tools. It is text-only in the supplied modality data, so vision use is not established. Listed pricing is $0.0825 per million input tokens and $0.1649 per million output tokens, substantially below the Pro version in this batch. For teams that need technical capability at volume, Flash is the more practical first deployment; reserve Pro for cases where its additional cost is justified by testing.
