| Input | $0.100/M |
| Output | $0.400/M |
| Context | 1M tokens |
| Best For | Simple queries, classification, fast responses |
Cost Comparison by Scenario
Estimated cost per project with 30% cache hit rate. Actual costs may vary based on usage patterns.
| Scenario | GPT-4.1 | GPT-4.1 Nano | Savings |
|---|---|---|---|
| Small Script (1K lines) | $0.31 | $0.02 | GPT-4.1 Nano saves $0.29 (95%) |
| Medium Feature (10K lines) | $2.30 | $0.12 | GPT-4.1 Nano saves $2.18 (95%) |
| Large Project (50K lines) | $11.50 | $0.58 | GPT-4.1 Nano saves $10.93 (95%) |
| Code Review (5K lines) | $0.55 | $0.03 | GPT-4.1 Nano saves $0.52 (95%) |
Verdict
GPT-4.1 Nano wins on both price and performance — $0.100/M input with a benchmark score of N/A/100.
For most developers, this is the clear choice between these two models.
