CORRECTED 2026-10-03 23:12 UTC — Correction — The original workload example overstated both dollar amounts by 1,000×. Using the rates quoted in this item, 500K prompt tokens cost $0.0077 before and $0.0094 after per request, excluding other charges. This verifies internal arithmetic only; historical source rate applicability and effective dates remain unverified.

WHAT CHANGEDOpenRouter raised the prompt token price for deepseek/deepseek-v4-flash-latest from $0.0154/M to $0.0188/M tokens, a 22.1% increase. Completion pricing remains $1.28/M tokens.
WHY IT MATTERSAny application using this model through OpenRouter will see prompt costs rise by roughly one-fifth. For workloads processing large context windows (this model supports 1M tokens), the increase compounds quickly—a 500K token prompt that cost $7.70 now costs $9.40.
WHAT TO DOReforecast your OpenRouter spend if you call this model. If prompt volume is high relative to completions, compare the new blended rate against other providers or DeepSeek's direct API to confirm OpenRouter remains cost-effective.
