GPT-5.2 pro vs GPT-5.5: Which Should You Choose?

Choosing between GPT-5.2 pro and GPT-5.5 depends on your priorities: cost efficiency, context length, or raw capability. GPT-5.5 is the more affordable option at $5.00/1M input tokens76% cheaper than GPT-5.2 pro. Meanwhile, GPT-5.5 offers a significantly larger context window at 1,050,000 tokens vs 1,000,000 for GPT-5.2 pro.

These models target different tiers: GPT-5.2 pro is a reasoning model while GPT-5.5 is flagship. This means they're optimized for different workloads. GPT-5.2 pro is built for complex tasks that require deeper reasoning, while GPT-5.5 offers better value for routine operations.

Output costs matter too. GPT-5.2 pro charges $168.00/1M output tokens vs $30.00 for GPT-5.5. For generation-heavy workloads (content creation, code generation, summarization), output pricing often dominates your bill. GPT-5.5 has the edge here at $30.00/1M output tokens.

Multimodal capabilities: Both models support vision (image understanding), so you can send images alongside text prompts with either option.
