GPT-5.2 pro vs GPT-5.5 Pro: Which Should You Choose?
Choosing between GPT-5.2 pro and GPT-5.5 Pro depends on your priorities: cost efficiency, context length, or raw capability. GPT-5.2 pro is the more affordable option at $21.00/1M input tokens — 30% cheaper than GPT-5.5 Pro. Meanwhile, GPT-5.5 Pro offers a significantly larger context window at 1,050,000 tokens vs 1,000,000 for GPT-5.2 pro.
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: GPT-5.2 pro would save you roughly $4,500.00/month compared to GPT-5.5 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 $180.00 for GPT-5.5 Pro. For generation-heavy workloads (content creation, code generation, summarization), output pricing often dominates your bill. GPT-5.2 pro has the edge here at $168.00/1M output tokens.
Multimodal capabilities: Both models support vision (image understanding), so you can send images alongside text prompts with either option.
