- Output Tokens: Words or content generated by the model
DeepSeek differentiates cache hits (repeated queries) from cache misses (new queries), with cache hits priced more affordably.
Standard Pricing (UTC 00:30–16:30)
DeepSeek-V3
- Input (Cache Hit): $0.07 / 1M tokens
- Input (Cache Miss): $0.27 / 1M tokens
- Output Tokens: $1.10 / 1M tokens
DeepSeek-R1
- Input (Cache Hit): $0.14 / 1M tokens
- Input (Cache Miss): $0.55 / 1M tokens
- Output Tokens: $2.19 / 1M tokens
Off-Peak Discounts (UTC 16:30–00:30)
DeepSeek rewards users who operate during non-peak hours:
DeepSeek-V3
- Input (Cache Hit): $0.035 / 1M tokens
- Input (Cache Miss): $0.135 / 1M tokens
- Output Tokens: $0.55 / 1M tokens
DeepSeek-R1
- Input (Cache Hit): $0.035 / 1M tokens
- Input (Cache Miss): $0.135 / 1M tokens
- Output Tokens: $0.55 / 1M tokens
These off-peak savings represent discounts of up to 75%, offering massive cost advantages for scheduled jobs or batch processing.
Try NowUsage Examples: Real-World Token Costs
Here’s what you get for 1 million tokens (roughly ~750,000 English words):
DeepSeek-V3 (Chat) Output
- Standard Rate: $1.10
- Off-Peak Rate: $0.55
DeepSeek-R1 (Reasoner) Output
