GPT-5.2 pro vs o4-mini Deep Research: Which Should You Choose?
Choosing between GPT-5.2 pro and o4-mini Deep Research depends on your priorities: cost efficiency, context length, or raw capability. o4-mini Deep Research is the more affordable option at $2.00/1M input tokens — 90% cheaper than GPT-5.2 pro. Meanwhile, GPT-5.2 pro offers a significantly larger context window at 1,000,000 tokens vs 200,000 for o4-mini Deep Research.
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: o4-mini Deep Research would save you roughly $29,700.00/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 $8.00 for o4-mini Deep Research. For generation-heavy workloads (content creation, code generation, summarization), output pricing often dominates your bill. o4-mini Deep Research has the edge here at $8.00/1M output tokens.
Multimodal capabilities: GPT-5.2 pro supports vision (image inputs) while o4-mini Deep Research 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)
- • You need longer outputs (up to 131,072 tokens)
- • You're already using OpenAI's API ecosystem
Choose o4-mini Deep Research when:
- • Budget is a primary concern
- • You're already using OpenAI's API ecosystem
