GPT-5.5

GPT-5.5 is OpenAI's newest frontier model for complex professional work — a fully retrained base model in the GPT-5 family. It excels at agentic coding, computer use, knowledge work, and scientific research, and is designed to plan, use tools, and carry multi-step tasks to completion autonomously. It achieves state-of-the-art scores on several benchmarks, including 82.7% on Terminal-Bench 2.0 (agentic coding workflows), 84.9% on GDPval (knowledge work across 44 occupations), and 78.7% on OSWorld-Verified (desktop computer use). It outperforms Claude Opus 4.7 and Gemini 3.1 Pro on most agentic and math benchmarks, though Opus 4.7 still leads on SWE-Bench Pro. Available with a 128,000 max output tokens. Supports image input, structured outputs, function calling, streaming, prompt caching, Batch, distillation, and a full Responses API tool suite including web search, computer use, MCP, hosted shell, and tool search. Defaults to medium reasoning effort (supports none through xhigh).

GPT-5.5 Pro

GPT-5.5 Pro is a version of GPT-5.5 that uses more compute to produce smarter, more precise responses on the hardest problems. It scores 39.6% on FrontierMath Tier 4 (expert-level mathematics) and 43.1% on Humanity's Last Exam (multidisciplinary zero-shot reasoning). Supports function calling, structured outputs, web search, file search, image generation, code interpreter, hosted shell, and MCP. Does not support computer use, apply patch, skills, tool search, or distillation. Shares the same 1,050,000-token context window and 128,000 max output tokens as GPT-5.5. Best suited for legal review, financial modeling, scientific research, and scenarios where first-pass accuracy outweighs cost and latency.

GPT Image 2

GPT Image 2 is OpenAI's state-of-the-art image generation and editing model, released in April 2026 as the successor to GPT Image 1. It accepts both text and image inputs, enabling generation from prompts as well as editing of existing images. The model is particularly strong at rendering text within images — signs, UI elements, labels, and multi-word strings — which was a persistent weakness in prior OpenAI image models. It also supports non-Latin scripts including Japanese, Korean, Chinese, Hindi, and Bengali. GPT Image 2 outputs up to 2K resolution, supports flexible image sizes, and can generate multiple images from a single prompt. It features a December 2025 knowledge cutoff and built-in reasoning capabilities. Ideal for developers building visual content pipelines, localized marketing assets, infographics, or UI mockups at scale.
