How to Save Even More

1. Use DeepSeek V4 Flash

For less complex tasks, Flash is half the price with minimal quality loss:

• V4: $0.27/$1.10 per M
• V4 Flash: $0.14/$0.55 per M

2. Implement Caching

Cache identical prompts. Many applications have 20-40% repeated queries.

3. Optimize Prompts

Shorter prompts = fewer input tokens = lower costs:

• Remove unnecessary context
• Use concise system prompts
• Limit user input length

4. Set max_tokens

Control output length to prevent runaway costs:

response = client.chat.completions.create(
    model="deepseek",
    messages=[{"role": "user", "content": "Summarize this"}],
    max_tokens=500  # Prevents excessively long responses
)

5. Use Subscription Plans

For predictable workloads, TokenEase subscriptions offer better value:

Plan	Monthly	Included Tokens	Effective Rate
Starter	$9.9	500K	$19.80/M
Pro	$29.9	3M	$9.97/M
Enterprise	$99.9	15M	$6.66/M

Subscriptions make sense if you use >300K tokens/month.
