GPT-5.2 vs o1: Which Should You Choose?

Choosing between GPT-5.2 and o1 depends on your priorities: cost efficiency, context length, or raw capability. GPT-5.2 is the more affordable option at $1.75/1M input tokens — 88% cheaper than o1. Meanwhile, GPT-5.2 offers a significantly larger context window at 1,000,000 tokens vs 200,000 for o1.

These models target different tiers: GPT-5.2 is a flagship model while o1 is reasoning. This means they're optimized for different workloads. GPT-5.2 is built for complex tasks that require deeper reasoning, while o1 offers better value for routine operations.

Output costs matter too. GPT-5.2 charges $14.00/1M output tokens vs $60.00 for o1. For generation-heavy workloads (content creation, code generation, summarization), output pricing often dominates your bill. GPT-5.2 has the edge here at $14.00/1M output tokens.

Multimodal capabilities: GPT-5.2 supports vision (image inputs) while o1 is text-only. If your application needs image understanding, this narrows your choice.

Best Use Cases

Choose GPT-5.2 when:

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