GPT-5.4 vs GPT-5.4 nano: Which Should You Choose?

Choosing between GPT-5.4 and GPT-5.4 nano depends on your priorities: cost efficiency, context length, or raw capability. GPT-5.4 nano is the more affordable option at $0.20/1M input tokens — 92% cheaper than GPT-5.4. Meanwhile, GPT-5.4 offers a significantly larger context window at 1,050,000 tokens vs 128,000 for GPT-5.4 nano.

These models target different tiers: GPT-5.4 is a flagship model while GPT-5.4 nano is efficient. This means they're optimized for different workloads. GPT-5.4 is built for complex tasks that require deeper reasoning, while GPT-5.4 nano offers better value for routine operations.

Output costs matter too. GPT-5.4 charges $15.00/1M output tokens vs $1.25 for GPT-5.4 nano. For generation-heavy workloads (content creation, code generation, summarization), output pricing often dominates your bill. GPT-5.4 nano has the edge here at $1.25/1M output tokens.

Multimodal capabilities: GPT-5.4 supports vision (image inputs) while GPT-5.4 nano is text-only. If your application needs image understanding, this narrows your choice.

Best Use Cases

Choose GPT-5.4 when:

• You need a larger context window (1,050,000 tokens)
• You need more capabilities (vision, code, reasoning)
• You need longer outputs (up to 131,072 tokens)
• You're already using OpenAI's API ecosystem

Choose GPT-5.4 nano when:

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