GPT-5.4 vs o1: Which Should You Choose?

Choosing between GPT-5.4 and o1 depends on your priorities: cost efficiency, context length, or raw capability. GPT-5.4 is the more affordable option at $2.50/1M input tokens — 83% cheaper than o1. Meanwhile, GPT-5.4 offers a significantly larger context window at 1,050,000 tokens vs 200,000 for o1.

These models target different tiers: GPT-5.4 is a flagship model while o1 is reasoning. This means they're optimized for different workloads. GPT-5.4 is built for complex tasks that require deeper reasoning, while o1 offers better value for routine operations.

Output costs matter too. GPT-5.4 charges $15.00/1M output tokens vs $60.00 for o1. For generation-heavy workloads (content creation, code generation, summarization), output pricing often dominates your bill. GPT-5.4 has the edge here at $15.00/1M output tokens.

Multimodal capabilities: GPT-5.4 supports vision (image inputs) while o1 is text-only. If your application needs image understanding, this narrows your choice.

Best Use Cases

Choose GPT-5.4 when:

• Budget is a primary concern
