GPT-5.2 pro vs GPT-5.4 nano: Which Should You Choose?
Choosing between GPT-5.2 pro 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 — 99% cheaper than GPT-5.2 pro. Meanwhile, GPT-5.2 pro offers a significantly larger context window at 1,000,000 tokens vs 128,000 for GPT-5.4 nano.
These models target different tiers: GPT-5.2 pro is a reasoning model while GPT-5.4 nano is efficient. This means they're optimized for different workloads. GPT-5.2 pro 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-5.2 pro charges $168.00/1M 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-5.2 pro 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-5.2 pro when:
- • You need a larger context window (1,000,000 tokens)
- • You need more capabilities (vision, audio, 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
