TL;DR

⚠️ Peak/Off-Peak Pricing (since Aug 16, 2026): DeepSeek now uses time-based pricing. Off-peak (most hours): $0.66/$1.98 per million tokens. Peak (01:00–04:00 and 06:00–10:00 UTC): $1.32/$3.96 — double the off-peak rate. Since Aug 23: weekends (Sat/Sun Beijing time) are all-day off-peak. Prices below show off-peak rates. Cached input tokens are $0.003625/M regardless of time.

DeepSeek V4 Pro Pricing Breakdown

Off-peak pricing at different monthly volumes (peak rates are 2× higher):

Monthly Volume Off-Peak Input Off-Peak Output Off-Peak Total (50/50)
1M tokens$0.66$1.98$1.32
10M tokens$6.60$19.80$13.20
100M tokens$66.00$198.00$132.00
1B tokens$660.00$1,980.00$1,320.00

At 100M tokens/month off-peak with a 50/50 input/output split, DeepSeek V4 Pro costs $132. Peak hours double these rates. Schedule heavy workloads during off-peak hours to minimize costs.

DeepSeek V4 Family: Pro vs Flash

Model Input $/M Output $/M Context Best For
DeepSeek V4 Flash $0.22 $0.66 1M Input-heavy tasks (classification, summarization)
DeepSeek V4 Pro $0.66 $1.98 1M Output-heavy tasks (generation, coding)

Decision guide: If your workload is input-heavy (classify, summarize, extract), choose V4 Flash at $0.22/$0.66. If it's output-heavy (generate, write, code), choose V4 Pro at $0.66/$1.98 — the output savings (3x cheaper) often outweigh the input premium.

GPT-5.6 Luna $0.20 $1.20 1.05M OpenAI
Claude Sonnet 5 $2.00 $10.00 1M Anthropic

DeepSeek V4 Pro has the lowest output price ($1.98) among all 1M-context models. Qwen 3.7 Flash is cheaper overall but has lower quality; GPT-5.6 Luna is comparable in quality but 38% more expensive on output.

When to Use DeepSeek V4 Pro

✍️ Content Generation

Generate articles, reports, or documentation at the lowest output cost. At $1.98/M output, it's the cheapest way to produce long-form text with 1M context.

💻 Code Generation

Generate code with full codebase context. 1M tokens fits entire repositories; low output pricing makes it ideal for code-heavy workloads.

💬 Chatbots

Build conversational AI where responses are longer than queries. The low output price means cheaper conversations at scale.

📝 Translation

Translate long documents where output length roughly matches input. The balanced input/output pricing makes it cost-effective for translation.

🔄 Data Transformation

Convert data between formats (JSON to CSV, code to documentation, structured to natural language). Output-heavy workloads benefit from the low output price.

📚 Summarization + Elaboration

Summarize long documents then elaborate on key points. 1M context handles the input; low output pricing makes the elaboration affordable.

Real-World Cost: Generating 50,000 Articles/Month

Suppose you're building a content generation service that produces 50,000 articles per month, averaging 1,000 input tokens (prompts) and 2,000 output tokens (articles) per request:

ModelInput CostOutput CostMonthly Total
DeepSeek V4 Pro$21.75$87.00$108.75
DeepSeek V4 Flash$7.00$28.00$35.00
Gemini 2.5 Flash$15.00$250.00$265.00
GPT-5.6 Luna$10.00$120.00$130.00
Claude Sonnet 5$100.00$1,000.00$1,100.00

DeepSeek V4 Pro at $108.75/month is cheaper than GPT-5.6 Luna ($130) and far cheaper than Gemini 2.5 Flash ($265) or Sonnet 5 ($1,100) for this output-heavy workload. V4 Flash is even cheaper if quality is sufficient.
