DeepSeek V4 Flash 0423 vs Kimi K2.5
Compare API prices, input formats and response limits. Start with the material your application needs to process and the budget for each request.
Kimi K2.5
- Input / 1M tokens
- $0.50
- Output / 1M tokens
- $2.50
The short answer
- Input and output tokens have separate prices. Check any long-prompt tiers below.
- A context allowance is a capacity limit, not evidence of answer quality or speed.
- Tool, media and reasoning charges can affect the complete API bill.
Estimate your monthly bill
Enter your own usage. We apply each model's current rates, including long-prompt pricing, for a 30-day month.

DeepSeek V4 Flash 0423$8.10per month
Kimi K2.5$67.50per month
A token is roughly three-quarters of an English word. Cached input, reasoning tokens, tools and media are not included.

API pricing
Prices are in USD per million tokens. Input is what you send; output is what the model generates. Chat subscriptions and API usage are billed separately.
Tools, images and additional reasoning can add charges. The examples below cover input and output tokens only.
Compare local modelsWhat those prices mean in practice
Each example uses the same token budget for both models. These are calculations, not measured workloads. Cache discounts, media, tools and extra reasoning are excluded.
| Workload | DeepSeek V4 Flash 0423 | Kimi K2.5 |
|---|---|---|
| 1,000 short requestsPer request: 2,000 input + 500 output tokens | $0.27 | $2.25 |
| 100 document summariesPer request: 20,000 input + 1,000 output tokens | $0.20 | $1.25 |
| 10 long-document requestsPer request: 300,000 input + 2,000 output tokens | $0.27 | Outside known limits |
Estimate = requests × (input tokens × input price + output tokens × output price) ÷ 1,000,000. Long-prompt rates are applied where the pricing data provides them. Real requests can use different amounts of output.
Choosing for your project
Start with the formats you need to send, then compare the context allowance and the cost examples. For an existing application, check tool calls and response formats before changing its model. A higher context limit or a lower token price does not, on its own, tell you which answer will be more useful.
