GPT-4.1 nano vs GPT-4o mini: Which Should You Choose?

Choosing between GPT-4.1 nano and GPT-4o mini depends on your priorities: cost efficiency, context length, or raw capability. GPT-4.1 nano is the more affordable option at $0.10/1M input tokens33% cheaper than GPT-4o mini.

Both models are in the efficient category, making this a direct head-to-head comparison. At scale — say 10,000 requests per day — the cost difference adds up: GPT-4.1 nano would save you roughly $45.00/month compared to GPT-4o mini. For startups and indie developers, that difference can be significant.

Output costs matter too. GPT-4.1 nano charges $0.40/1M output tokens vs $0.60 for GPT-4o mini. For generation-heavy workloads (content creation, code generation, summarization), output pricing often dominates your bill. GPT-4.1 nano has the edge here at $0.40/1M output tokens.

Multimodal capabilities: GPT-4o mini supports vision (image inputs) while GPT-4.1 nano is text-only. If your application needs image understanding, this narrows your choice.

Best Use Cases

Choose GPT-4.1 nano when:

  • • Budget is a primary concern
  • • You're already using OpenAI's API ecosystem
  • • You're running high-volume, latency-sensitive workloads

Choose GPT-4o mini when:

  • • You need more capabilities (vision)
  • • You need longer outputs (up to 16,384 tokens)
  • • You're already using OpenAI's API ecosystem
  • • You're running high-volume, latency-sensitive workloads
