Overview

DeepSeek: DeepSeek V4 Flash 0423 is a large language model API from DeepSeek, part of its DeepSeek V4 model family. At $0.049 per million input tokens and $0.098 per million output tokens, it sits in the budget tier — among the cheaper options for high-throughput or cost-sensitive workloads. Output tokens cost about 2× as much as input, so prompt-heavy workloads run noticeably cheaper than generation-heavy ones. An exceptionally large 1.05M-token context window (≈1,573 pages of text) means entire repositories or document collections can be processed without chunking. On Artificial Analysis's Intelligence Index it scores 25 (D grade), a useful proxy for its general reasoning strength relative to the other models tracked here. All prices on this page reflect OpenRouter's routed rates and are re-synced automatically every day; confirm against the provider's official pricing before committing to production.
