GPT-5.4 Nano vs GPT-4.1 Nano
Last updated: July 2026 | Pricing verified: July 2026
GPT-5.4 Nano is newer, but GPT-4.1 Nano is cheaper on input. In July 2026, OpenAI lists GPT-5.4 Nano at $0.20/M input and $1.25/M output, while GPT-4.1 Nano is $0.10/M input and $0.40/M output.
For Indian developers, that price gap is large enough to matter. GPT-5.4 Nano is not the automatic budget pick.
Search Intent Notes
| Question | Practical answer |
|---|---|
| Main intent | Pick the cheaper OpenAI model |
| Strongest reason not to choose GPT-5.4 Nano | Output is 3.125x more expensive than GPT-4.1 Nano |
| Sensible tier for India | GPT-4.1 Nano for simple tasks, GPT-5.4 Nano for harder low-cost tasks |
| Hidden limitation | "Nano" does not mean same price across generations |
| Verdict | Start with GPT-4.1 Nano, upgrade only failing prompts |
Pricing in INR
At $1 = ā¹95.21:

When to Use GPT-4.1 Nano
Use it for:
- classification
- short JSON extraction
- basic rewriting
- routing
- keyword generation
- low-risk internal tools
It is the better default if your prompts are simple and you care about cost.
When to Use GPT-5.4 Nano
Use it when:
- GPT-4.1 Nano fails too often
- prompts need more reasoning
- output quality affects user trust
- you still want to stay inside OpenAI's low-cost tier
GPT-5.4 Nano is a quality upgrade, not a pure savings move.
India Payment Notes
Both models use OpenAI API billing in USD. Indian users should assume international card requirements. UPI is not the normal path for OpenAI API billing.
Final Verdict
For Indian developers, GPT-4.1 Nano is the better budget default. Use GPT-5.4 Nano only for prompts where the older nano model fails quality checks.
The practical setup: run both on a small set of your real prompts, not generic benchmarks. If GPT-4.1 Nano passes, keep the money.
