When DeepSeek Pricing Makes Sense

Choose DeepSeek V4 Flash when:

• Cost is a primary constraint
• Task is coding, math, instruction following, or analysis
• You need up to 1M context and do not need vision

Choose DeepSeek V4 Pro when:

• You need stronger reasoning
• You want thinking-mode output in reasoning_content
• Higher output cost is acceptable

Choose Claude or GPT when:

• You need vision/multimodal inputs
• Task requires nuanced creative writing
• You need guaranteed enterprise SLAs

DeepSeek Context Window and Pricing

DeepSeek V4 Flash and V4 Pro support a 1M-token context window. Long-context calls are priced at the standard per-token rate.

Tip: Use prompt caching for repeated system prompts where supported. Check marketplace pricing and billing logs for the current cached-input rate.

# Cache the system prompt by placing it first consistently
response = client.chat.completions.create(
    model="deepseek-v4-flash",
    messages=[
        {"role": "system", "content": YOUR_LONG_SYSTEM_PROMPT},  # cached
        {"role": "user", "content": user_message},
    ],
)
