Overview

GPT-5 is OpenAI’s most intelligent model yet, and it brings major gains across reasoning, reliability, and specialized use cases.

Dynamic reasoning (“think hard about this”) enables expert-level responses on complex tasks

Much better at complex front-end generation

Best model yet for health-related questions

Significant reductions in hallucinations (~80% less with thinking mode vs. o3)

It supports a 400,000 token context window and up to 128,000 output tokens

Earlier iterations of this model were available as Horizon Alpha and Horizon Beta

SWE-Bench Verified (500 turns)

Model Accuracy

Open AI GPT-5 74.9%

Claude Sonnet-4 70.4%

Qwen3-Coder 69.6%

OpenAI o3 69.1%
