Pricing and access
Historical DeepSeek V4 Flash 0731 checkpoint: DeepSeek has retired the model formerly served by deepseek-v4-flash. This legacy API alias now serves DeepSeek V4.1 Flash and uses that newer model's pricing. Current direct-API pricing for this historical checkpoint is unavailable; prior $0.14 input/$0.28 output rates are historical, not a current offer. Historical benchmark observations are retained for the named checkpoint.
