GPT-5.2 pro vs o1-mini: Which Should You Choose?
Choosing between GPT-5.2 pro and o1-mini depends on your priorities: cost efficiency, context length, or raw capability. o1-mini is the more affordable option at $1.10/1M input tokens — 95% 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 o1-mini.
Both models are in the reasoning category, making this a direct head-to-head comparison. At scale — say 10,000 requests per day — the cost difference adds up: o1-mini would save you roughly $30,510.00/month compared to GPT-5.2 pro. For startups and indie developers, that difference can be significant.
Output costs matter too. GPT-5.2 pro charges $168.00/1M output tokens vs $4.40 for o1-mini. For generation-heavy workloads (content creation, code generation, summarization), output pricing often dominates your bill. o1-mini has the edge here at $4.40/1M output tokens.
Multimodal capabilities: GPT-5.2 pro supports vision (image inputs) while o1-mini 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)
- • You need longer outputs (up to 131,072 tokens)
- • You're already using OpenAI's API ecosystem
Choose o1-mini when:
- • Budget is a primary concern
- • You're already using OpenAI's API ecosystem
