ChatGPT vs Grok in 2026: ChatGPT Plus is $20 and SuperGrok $30, with Lite at $10 and Heavy at $300. ChatGPT covers more work; Grok leads on X and video.
ChatGPT and Grok are two of the most-used AI assistants, and in 2026 they have converged on similar price ladders: a budget tier, a main plan, a $100 plan and a premium tier above it. They differ in what each ladder buys. ChatGPT is a broad work tool with coding, research and productivity features built in. Grok, made by SpaceXAI, the AI division SpaceX formed after absorbing Elon Musk's xAI in 2026, is tied to X, strong on real-time trends, and the only one of the two that still makes video.
How we compared: ChatGPT's and Grok's plan pages checked on September 29, 2026, with Grok's prices read from grok.com in US dollars and ChatGPT's from OpenAI's pricing pages. This is a researched comparison, not a side-by-side test.
Work, study and coding: ChatGPT. Plus includes GPT-6 reasoning, Codex, deep research, projects, scheduled tasks and custom GPTs for $20.
Following news and conversation on X: Grok. It draws on posts from X in real time, and the top plan even includes X Premium+.
Making video: Grok. SuperGrok makes 720p clips up to 30 seconds, Plus adds 1080p, and ChatGPT stopped offering video when Sora closed.
Spending as little as possible: ChatGPT. Its free plan allows unlimited text chats, and Go costs $8 against $10 for SuperGrok Lite.
| ChatGPT | Grok | |
|---|---|---|
| Free | Unlimited text chats with GPT-5.6 Luna, limited images, voice, deep research and Codex; ads in the US | Basic access with tighter limits |
| Budget | Go: $8 a month, more messages, uploads and images; may include ads | SuperGrok Lite: $10, Expert mode, 2x longer conversations, app building, a taste of image and video |
| Main plan | Plus: $20, GPT-6 reasoning, Codex, projects, scheduled tasks, custom GPTs | SuperGrok: $30, Grok Bot, 5x longer conversations, 720p video up to 30 seconds, longer voice chats |
| $100 tier | Pro 100: $100, GPT-6 Astra, longer Codex and Work sessions, unlimited images | SuperGrok Plus: $100, 1080p video, much higher usage, priority at peak times |
| Premium tier | Pro 200 at $200 (10x Plus for Work and Codex) or Pro 500 at $500 (25x, Ultrafast) | SuperGrok Heavy: $300, multi-agent Grok Heavy, X Premium+ included |
Grok also offers annual billing at a discount, and both companies sell business plans.
Rung by rung, ChatGPT is cheaper at the bottom and in the middle: $8 against $10, and $20 against $30 for the main plan. The $100 tiers match on price. At the top, Grok's $300 Heavy plan bundles a multi-agent mode and an X subscription, while ChatGPT's higher Pro tier sells more of the same usage.
Grok's distinguishing feature is its connection to X. It can search and summarize posts as they happen, which makes it useful for tracking breaking news, public reaction and trends that have not yet reached news sites. It also lives inside the X app, so people who already spend time there have it one tap away.
Media is its second edge. Grok Imagine creates images and videos: SuperGrok makes HD 720p clips up to 30 seconds long, and SuperGrok Plus adds 1080p. ChatGPT still generates and edits images but no longer makes video, since OpenAI closed the Sora app in April 2026 and its API in September. Grok's voice mode gets longer conversations on SuperGrok, and the plans also include a Build feature for creating apps from a single prompt with one-tap deployment to the web.
Grok's tone is the third difference. Its makers positioned it as less filtered than rivals, and many users choose it for blunter, less hedged answers. That reputation cuts both ways: Grok's image features were tightened during 2026, and our Grok review found image generation had been removed from the free tier in March.
ChatGPT's $20 Plus plan is a wider product. GPT-6 reasoning handles analysis and writing, deep research produces cited reports, projects and memory organize long-running work, scheduled tasks run on their own, and custom GPTs and apps connect to other services. ChatGPT Work extends the assistant across desktop, web and mobile for work tasks, and study mode, a built-in browser and interactive apps round it out.
Coding is where the gap is widest. Every ChatGPT plan includes Codex, OpenAI's agent for the terminal, IDEs and the cloud, and OpenAI publishes estimated message counts per model and plan, such as 15 to 150 GPT-6 Sol messages per five hours on Plus. Grok lists "more powerful coding tools" on SuperGrok and is available as a model in editors such as Cursor, but it has no equivalent of Codex bundled into its consumer plans. Its owner does have a coding product: SpaceX bought Cursor's maker in 2026.
ChatGPT's free plan is the more generous: text chats with GPT-5.6 Luna are unlimited within abuse guardrails, and images, voice, deep research, uploads and Codex are included in limited amounts. The trade-off is advertising, which began on the Free and Go plans in the US in February 2026; Plus and above are ad-free.
Grok's free access is more limited, with the plans page positioning Lite at $10 as the step up for people who want to keep chatting with basic access, and image and video creation reserved mainly for paid plans. For someone who does not want to pay, ChatGPT is the better free assistant.
ChatGPT takes the verdict because it gives more for less at the tiers most people buy: a stronger free plan, a cheaper main plan at $20 against $30, and a much broader set of work, research and coding tools, including Codex. For writing, analysis, study and software, it is the better assistant.
Grok is the better choice for three groups: people who live on X and want real-time posts and trends summarized, creators who want video generation in their chatbot subscription, and users who prefer its blunter style.

For most work, no. ChatGPT's $20 Plus plan includes GPT-6 reasoning, Codex, deep research, projects, scheduled tasks and custom GPTs, and its free plan offers unlimited text chats. Grok is better for real-time posts and trends from X, for AI video, which ChatGPT no longer offers since Sora closed, and for people who prefer its looser tone. Most people get more from ChatGPT; X-heavy users and video makers may prefer Grok.
SuperGrok costs $30 a month and ChatGPT Plus $20. Both companies sell a cheaper tier, SuperGrok Lite at $10 and ChatGPT Go at $8, and a $100 tier, SuperGrok Plus and ChatGPT Pro 100. At the top, SuperGrok Heavy costs $300 a month, while ChatGPT now sells Pro 200 at $200 and, since September 29, 2026, Pro 500 at $500. Grok offers a discount for annual billing.
Everything in SuperGrok Plus, the highest usage limits at the fastest speed, Grok Heavy, which runs a larger team of agents that collaborate on hard problems, dedicated support, early access to features and an X Premium+ subscription at no extra cost once you connect your X account. It costs $300 a month and is aimed at people who push the hardest reasoning problems through Grok daily.
Grok can. SuperGrok makes 720p videos up to 30 seconds long through Grok Imagine, and SuperGrok Plus adds 1080p. ChatGPT creates and edits images on every plan but no longer makes video: OpenAI closed the Sora app in April 2026 and the Sora API on September 24, 2026. For video, Grok or a dedicated generator is the choice.
ChatGPT, for most developers. Every ChatGPT plan includes Codex, OpenAI's coding agent for the terminal, IDE and cloud, with published usage estimates per plan. Grok's plans list app building from a single prompt with one-tap deployment from Lite and more powerful coding tools from SuperGrok, and editors such as Cursor offer Grok models too.
ChatGPT's Free and Go plans can include ads, which began in the US in February 2026, while Plus and higher plans are ad-free. Grok's plans page does not mention ads. If ads are a dealbreaker, ChatGPT Plus at $20 is the cheapest ad-free ChatGPT option.
