모델 소개

OpenAI GPT-5.5

GPT-5.5 is OpenAI's frontier model released on April 23, 2026, designed for complex professional workloads including agentic coding, computer use, and deep research. Building on GPT-5.4, it delivers stronger reasoning, higher reliability with 60% fewer hallucinations, and improved token efficiency — matching GPT-5.4 per-token latency while performing at a significantly higher level of intelligence. It features a 1M+ token context window (922K input, 128K output) with support for text and image inputs.

Why It Looks Great

Frontier-class reasoning with 88.7% SWE-bench Verified and 92.4% MMLU scores
1M token context window for large-scale reasoning, coding, and multimodal workflows
60% fewer hallucinations compared to GPT-5.4 with improved token efficiency
Three variants: standard, Thinking (extended reasoning), and Pro (highest accuracy)
Same per-token latency as GPT-5.4 despite the intelligence leap

Key Features

Context Window: 1050000 tokens
Max Input: 922000 tokens
Max Output: 128000 tokens
Vision: Supported
Function Calling: Supported
Thinking Mode: Supported (low / medium / high / xhigh effort levels)
Variants: GPT-5.5, GPT-5.5 Thinking, GPT-5.5 Pro

Note: GPT-5.5 is 2× GPT-5.4 at the token level, but uses significantly fewer tokens to complete the same tasks. Independent testing puts the net cost increase at roughly 20% once token efficiency is factored in.

How to Use

Write your prompt — describe the task, provide context, and specify desired output format.
Submit — the model processes your request and returns the response.
