Full specs, context window and API limits →How much does DeepSeek V4 Flash cost per million tokens?
DeepSeek V4 Flash costs $0.44 per million input tokens and $1.32 per million output tokens ($0.66/M blended at 3:1). A high-efficiency open-weights model designed for rapid classification, document summarization, and large-scale data structuring. Verified 2026-09-08.
How much does DeepSeek V4 Flash cost per 1,000 requests?
Computed from generated token pricing. Each row assumes the listed input and output tokens per request; output is adjusted by this model's measured 2.59× verbosity factor.
| Request shape | Input tokens | Output tokens | Cost / 1,000 requests |
|---|---|---|---|
| Short | 100 | 50 | $0.2149 |
| Medium | 1,000 | 500 | $2.1494 |
| Long | 4,000 | 2,000 | $8.5976 |
Formula: ((input price × input tokens) + (output price × output tokens × verbosity factor)) ÷ 1,000,000 × 1,000. Assumptions: short 100/50, medium 1,000/500, long 4,000/2,000 input/output tokens per request. Verbosity run: 2026-06-16T20:31:30.728Z.
Three model-specific pricing decisions
Flash is non-thinking mode, so the schedule and accepted-answer boundary stay separate from provider-wide scheduling and the broad Flash/Pro comparison.
1. UTC peak/off-peak plus cache-hit monthly schedule
| UTC traffic | Cache status | Formula | Decision |
|---|---|---|---|
| Peak allocation p | Hit/miss separate | p × peak + (1 − p) × off-peak | Measure p in UTC |
| Off-peak allocation 1 − p | Hit/miss separate | 100K calls × applicable input/output rates | Schedule flexible work |
| Dated rate | Model price record | Current Flash rate only | Provider schedule source required for numeric discount |
2. Flash versus Pro cost-per-accepted-answer boundary
| Mode | Token cost / 100K | Accepted-answer rate | Boundary |
|---|---|---|---|
| DeepSeek V4 Flash | $237.60 | Unavailable | Thinking premium cannot be inferred |
| DeepSeek V4 Pro | $712.80 | Unavailable | Record accepted answers before switching |
3. Operational sensitivity
| Variable | Dated value | Keep separate from token price |
|---|---|---|
| Retry rate | Unavailable | Multiply full request cost when measured |
| Latency | Unavailable | Do not convert milliseconds to dollars |
| SLA / availability | Unavailable | No SLA claim in pricing record |
