Editorial excerpt
GPT-5.5
AI-assisted, editorially reviewed
This model is still under editorial review. We will publish a verdict as soon as we have completed our review of the AI model.
OpenAI’s GPT-5.5 is the best all-round AI subscription for buyers who want one powerful assistant that can do far more than answer questions. It combines polished writing, sharp research, coding help, data analysis, document creation, tool use, and superb built-in image generation inside one familiar workspace. Its biggest upgrade over GPT-5.4 is follow-through: it is better at taking messy, multi-step requests and turning them into finished work with less hand-holding. For non-technical users who want the most complete, capable, and easy-to-live-with AI experience, GPT-5.5 is the safest premium choice.
GPT-5.5 sits inside the best complete AI workspace: writing, research, coding help, data analysis, documents, spreadsheets, tool use, and now very strong built-in image generation. OpenAI’s own release notes describe GPT-5.5 as built to understand complex goals, use tools, check its work, and carry multi-step tasks through to completion. ChatGPT Images 2.0 also adds stronger image generation, better text rendering, multilingual support, flexible visual styles, and more advanced creative control.
