Real Cost Scenarios
Scenario 1: Chatbot for 1,000 Daily Users
Average conversation: 2,000 input + 500 output tokens per message × 10 messages/day × 1,000 users × 30 days = 600M input + 150M output tokens/month
| Model | Monthly Cost | |-------|-------------| | Qwen3-8B ($0.01/$0.01) | $7.50 | | DeepSeek V4 Flash ($0.18/$0.25) | $146 | | GLM-5 ($0.73/$1.92) | $726 | | Kimi K2.5 ($0.59/$3.00) | $803 |
Starting with DeepSeek V4 Flash ($146/month) then optimizing to Qwen3-8B ($7.50/month) for simple queries saves 95%.
Scenario 2: AI-Powered Code Assistant (Solo Developer)
~50 requests/day, 3,000 input + 2,000 output tokens each = 150K input + 100K output/day ≈ 4.5M input + 3M output/month
| Model | Monthly Cost | |-------|-------------| | DeepSeek V4 Flash | $1.47 | | DeepSeek Coder | $1.47 | | Qwen3-Coder-30B | $1.85 | | DeepSeek V4 Pro | $4.91 |
For a solo developer, DeepSeek V4 Flash costs less than a coffee per month.
Scenario 3: Enterprise SaaS (10M API Calls/Month)
Average: 500 input + 800 output tokens per call × 10M = 5B input + 8B output tokens/month
| Model | Monthly Cost | |-------|-------------| | DeepSeek V4 Flash | $2,940 | | Qwen3-32B | $3,140 | | DeepSeek V4 Pro | $9,110 | | Kimi K2.5 | $26,950 |
