ChatGPT
OpenAI's flagship AI assistant with o3/o4-mini reasoning, GPT-4o, Advanced Voice, Sora video gen, Operator agent, and Deep Research — the most feature-packed chatbot available.
Pricing verified 2026-05-02
Overview
ChatGPT remains the most widely-used AI assistant in the world, now serving over 400 million users. OpenAI has aggressively expanded its capabilities throughout 2025-2026, turning what started as a chatbot into a full-stack AI platform combining reasoning (o3, o4-mini), conversation (GPT-4o), image generation, video creation via Sora, Advanced Voice Mode, and agentic computer use through Operator.
The o3 and o4-mini reasoning models handle complex math, science, and logic problems with genuine chain-of-thought reasoning, while GPT-4o remains the fast, versatile default for everyday tasks. Deep Research mode lets ChatGPT autonomously browse dozens of sources and compile structured reports — a genuine time-saver for anyone doing serious research. Operator, the agentic browsing feature, can navigate websites and complete tasks like booking reservations or filling out forms.
The competitive landscape has tightened considerably since 2024. Claude now matches or exceeds ChatGPT in writing quality and coding, Gemini offers deeper Google ecosystem integration, and Perplexity is stronger for pure research. But no single competitor matches ChatGPT's sheer breadth of capabilities in one product. If you want one AI subscription that covers everything, this is still the default choice — just not the runaway leader it once was.
Key features
Reasoning Models
o3 and o4-mini reasoning models for step-by-step thinking on math, science, coding, and complex analysis. o3 is the heavyweight; o4-mini is faster and more efficient for everyday reasoning tasks.
Agentic Capabilities
Operator agent browses the web and completes multi-step tasks autonomously. Deep Research mode investigates topics across dozens of sources and produces structured reports with citations.
Multimodal I/O
Advanced Voice Mode for natural spoken conversations, GPT-4o vision for image understanding, native image generation, Sora for video creation, code execution, file analysis, and web browsing.
Canvas & Memory
Canvas provides a side-by-side editor for writing and code with inline AI suggestions. Persistent memory remembers your preferences and context across conversations.

Pros & cons
Pros
- ✓Widest feature set of any AI assistant — voice, vision, image gen, video, code, browsing, and agents in one app
- ✓o3 and o4-mini reasoning models are top-tier for complex problem-solving
- ✓Operator agent and Deep Research add genuinely useful autonomous capabilities
- ✓Free tier now includes limited GPT-4o access, not just the mini model
Cons
- ×Pro plan at $200/mo is hard to justify unless you need heavy o3 or Operator usage
- ×Writing quality has fallen behind Claude for nuanced, long-form content
- ×Custom GPT ecosystem is broad but quality varies wildly — lots of low-effort entries
- ×Privacy concerns remain: conversations used for training unless you opt out
