ChatGPT vs Midjourney

ChatGPT

OpenAI's conversational AI assistant

ChatGPT is an AI assistant from OpenAI. People use it to ask questions, write and edit text, brainstorm, analyse documents and data, write and debug code, generate images, learn new subjects and carry out tasks, through a conversational interface on the web, desktop and mobile apps. Its launch in November 2022 marked a turning point for artificial intelligence. ChatGPT reached a huge user base faster than almost any consumer product before it, introduced the general public to large language models and started the wave of generative AI products and investment that followed. It remains the most widely used AI assistant. The product has expanded far beyond text chat. It can search the web and cite sources, analyse uploaded files such as PDFs and spreadsheets, run code to analyse data and create charts, generate and edit images, and hold real-time voice conversations. Custom GPTs let users and companies build specialised assistants for particular tasks, projects organise chats and files around a goal, memory allows it to remember preferences across conversations, and deep research produces long, sourced reports on complex questions. Agent capabilities let it carry out multi-step tasks on the web on the user's behalf. ChatGPT has a free tier and paid subscriptions that offer more capable models, higher usage limits and advanced features, plus Team and Enterprise plans with administration, privacy commitments and data controls for organisations. Developers access the underlying models separately through OpenAI's API. The limitations are those of current language models. It can state incorrect information confidently, its knowledge has cut-off dates unless it searches, and outputs need checking for important decisions. Privacy and data-handling policies matter for sensitive information, and organisations often prefer business plans that exclude their data from training. Alternatives include Claude from Anthropic, known for writing quality and long documents; Google Gemini, integrated with Google's services; Microsoft Copilot for Microsoft 365 users; Perplexity for answer-engine search with citations; Meta AI inside Meta's apps; and Mistral's Le Chat. Choose ChatGPT when you want the most widely used general-purpose AI assistant with a broad feature set.

Midjourney

Generate original images from text prompts

Midjourney is a text-to-image generator with a house style, and that is both the product and the criticism. It has consistently produced the most immediately attractive default output of any image model — lighting, composition and material rendering that look considered rather than assembled — and the trade is that images from it are often recognisable as coming from it. It began as a Discord bot and still runs there, but there is now a full web application at midjourney.com where you generate, browse your history, edit and organise, so the "you have to learn Discord first" objection has largely gone. The controls that matter are parameters rather than prompts: aspect ratio, stylize (how much of the house aesthetic to apply), chaos (variation across the initial grid), and weird. Image prompts and style references let you carry a look across a set, which is what makes it usable for a brand rather than for one-off pictures. There is also a video generation mode, which is where the heaviest compute goes. Pricing is paid only — there is no free tier. Basic is $10 a month, Standard $30, Pro $60 and Mega $120, each about 20% cheaper billed annually ($8, $24, $48 and $96). The unit you are buying is fast GPU time, not a number of images: 3.3 hours on Basic, 15 on Standard, 30 on Pro and 60 on Mega. A still image costs roughly a GPU minute, while video costs an order of magnitude more, so Basic is a few hundred stills and Standard adds unlimited generations in the slower relax queue, which is the single biggest jump in practical value. Stealth mode, which keeps your generations out of the public gallery, only starts at Pro — everything on the cheaper plans is visible to other users. The real limitations are control and text. It is deliberately opinionated, so precise layout instructions are harder to land than in tools built around editing, and rendering long strings of legible text remains its weakest area. Against DALL·E inside ChatGPT, Midjourney is better looking and worse at following literal instructions. Ideogram is the one to reach for when the image has to contain readable text. Stable Diffusion and Flux, run locally or through a host, trade convenience for total control, custom models and no per-image cost. Adobe Firefly is the choice when the licensing provenance of the training data has to satisfy a legal team. Choose Midjourney when the picture has to be beautiful. Choose something else when it has to be exact.
