What makes GPT-4.1 truly impressive is how it breaks the conventional wisdom of “high performance = high cost.” Let’s see how it actually differs from previous models in the table below!
📊 API Pricing Comparison (As of April 2025)
| Model | Input Price (per 1K tokens) | Output Price (per 1K tokens) | Features |
|---|---|---|---|
| GPT-4.1 | Approx. $0.005-$0.01 | Approx. $0.015-$0.03 | High performance + Cost-optimized model |
| GPT-4o (Open) | Approx. $0.01 | Approx. $0.03 | High accuracy + Multimodal support |
| GPT-4.5 (Legacy) | Approx. $0.03-$0.06 | Approx. $0.06-$0.12 | High accuracy but costly, scheduled for discontinuation |
📝 Note: 1K tokens ≈ 750 words in English, 500 characters in Japanese
🧮 Monthly Cost Simulation
For example, when using the API for 10,000 tokens per day for 30 days:
| Model | Monthly Estimate (Approximate) |
|---|---|
| GPT-4.5 | Approx. $180-$360 |
| GPT-4o | Approx. $120 |
| GPT-4.1 | Approx. $30-$60 |
👉 Just by switching to GPT-4.1, you can save up to $300 per month!
