DeepSeek V4 Flash: Artificial Analysis breaks down its speed and price

DeepSeek V4 Flash hits the sweet spot between fast reasoning and cheap API bills.

Artificial Analysis published a performance breakdown of DeepSeek V4 Flash using its updated Intelligence Index v4.1. The testing firm ran the model across nine benchmark evaluations — covering coding, math, agentic operations, and hallucination rates — to measure its intelligence against its actual cost per task.

Why it matters: High-performing models often come with steep token prices or slow responses. Artificial Analysis places DeepSeek V4 Flash right on the Pareto line, delivering strong intelligence metrics without forcing developers to choose between speed and cost.

Know this: The evaluation factors in full pricing mechanics — input, output, reasoning tokens, and cache hits — alongside total active parameters and context limits.

Your API budget just got some breathing room.
