OpenAI GPT-5.5 Pro

GPT-5.5 Pro is the highest-accuracy variant of OpenAI's GPT-5.5 frontier model, released April 23, 2026. It applies parallel test-time compute on top of the same GPT-5.5 base model to maximize correctness on hard tasks — targeting professional research, complex multi-step analysis, and production-grade agentic workflows where getting the answer right matters more than speed or cost. Available to Pro, Business, and Enterprise users in ChatGPT, and via the Responses API for developers.

Why It Looks Great

Highest-accuracy mode in the GPT-5.5 family, built for correctness-critical workloads
1M token context window (922K input, 128K output) for large-scale document reasoning
Parallel test-time compute delivers stronger results on hard coding, research, and analysis tasks
Same 60% hallucination reduction and multimodal capabilities as GPT-5.5 standard
Responses API support for structured agentic tool-use workflows

Key Features

Context Window: 1050000 tokens
Max Input: 922000 tokens
Max Output: 128000 tokens
Vision: Supported
Function Calling: Supported
Thinking Mode: Supported (extended parallel reasoning)
API: Responses API only

Benchmarks

GPT-5.5 Pro is 6× the standard GPT-5.5 price. Use it for tasks where correctness justifies the cost — complex research synthesis, high-stakes code generation, and production decision support. For routine workloads, GPT-5.5 standard at $5/$30 is the better fit.

How to Use

Write your prompt — describe the task, provide context, and specify desired output format.
Submit — the model applies extended parallel reasoning and returns the response.
