ChatGPT
Overview
ChatGPT is OpenAI's conversational AI app and the most widely used general-purpose AI assistant as of 2026. Available on Web, iOS, Android, macOS and Windows, it bundles voice mode, Deep Research, image generation (DALL·E 3), video generation (Sora), and Custom GPTs into a single experience. Since late 2025, ChatGPT has run on the GPT-5 family, and in March 2026 GPT-5.4 rolled out to all plans.
Latest / Key Features
Migration to GPT-5.4
On March 5, 2026, GPT-5.4 rolled out across Free, Go, Plus, and Pro plans. Free uses GPT-5.3, Go uses GPT-5.2 Instant by default, and Plus and above unlock GPT-5.4 Thinking for deeper reasoning.
Ads on Free and Go plans (US)
Starting in February 2026, OpenAI began testing in-conversation ads for US users on the Free and Go plans. Paid Plus and above remain ad-free.
Deep Research
Generates long-form reports by crawling dozens to hundreds of web sources. Limited quota on Plus, effectively unlimited on Pro. Outputs include citations, making it popular for research and reporting workflows.
Custom GPTs / GPT Store
Users can create and share their own GPTs. The GPT Store hosts millions of Custom GPTs and is available to Plus and above.
Sora Video Generation
Sora 2-based video generation is now integrated directly in ChatGPT. Plus users get limited access; Pro unlocks higher resolution and longer clips.
Advanced Voice Mode
Low-latency, emotionally expressive voice chat with support for interruptions and multiple languages.
