Grok vs ChatGPT (2026): Prices, Limits and Which One to Pick

Short answer (November 2026): Both are free to start, and both have an $8 a month plan. Pick ChatGPT for study, long documents and everyday work. Its main paid plan costs $20 a month. Pick Grok if you want answers that draw on posts from X, or if you make a lot of images and short videos. Grok's matching plan costs $30 a month.
We checked plans on xAI's and OpenAI's own documentation and pricing pages in November 2026. Plans change often, so check Grok pricing and ChatGPT pricing before you pay.

Limits
Neither company gives one simple message count for its chat plans.
Grok: Paid plans share one weekly usage pool across Grok products. It resets on a schedule shown in Settings, under Usage. Free users get separate limits for Chat and Voice, and xAI does not publish the numbers. On paid plans, compared with Plus, Premium gives 4 times the usage, Super gives 15 times and Ultra gives 50 times. You can buy extra credits from $5.
ChatGPT: Free has limited messages with uploads, image creation, voice and deep research. Go has more. Plus has expanded limits, and OpenAI does not list a fixed number for them. Pro comes in three usage tiers.
ChatGPT also tells you how much text each plan can hold in one conversation. Plus can take about 40 pages in everyday chat, and about 320 pages with a reasoning model. Free can take about 12 pages in everyday chat.
Because neither side publishes full numbers, you can't compare the allowances directly. The best test is one week of your normal use on the free plan.
Models
Grok: xAI's developer docs name Grok 4.7 as its flagship model. They also list separate models for images and video. xAI's docs don't list which model each consumer plan gets.
ChatGPT: Free and Go chat with GPT-6 Luna. Plus adds GPT-6.1 Sol, GPT-6 Sol and GPT-6 Astra, along with older models. Pro has the highest limits on those models.
We don't rank them with benchmark scores. Results change with each new model, and published tests often disagree.
What Each One Does Best
Grok is strong at:
- Questions about what people are posting on X now
- Making images and short videos with Grok Imagine
- Spending one weekly pool across chat, voice, images and video
- Handing longer jobs to Grok Bot, on Premium and higher plans
Images and videos made in Grok carry a watermark that you can't turn off.
ChatGPT is strong at:
- Working through long files, with clear page limits per plan
- Deep research reports
- Memory that carries across chats
- Coding and office tasks through Codex and ChatGPT Work, which start on the free plan with limited access
Which One to Pick
Students
Start with ChatGPT Free. It handles everyday questions, and its paid plan is the cheaper of the two main plans at $20. Ask it to explain ideas step by step and check its facts against your course notes.
Try Grok Free as a second tool when a topic is changing fast and you want to see what people are saying. Posts are opinions, so confirm any fact in a better source before you use it in your work.
OpenAI's most recent student offer closed on October 31, 2026, and it covered only some schools. We did not find a student offer on the xAI pages we could read.
Research on current events
Use Grok to see the conversation on X. Use ChatGPT deep research when you want a longer report. Open the sources in both cases.
Writing and long documents
Use ChatGPT. Its stated page limits make it easier to know whether your file will fit.
Images and short videos
Try Grok Imagine first if you want to make many quick drafts and the watermark is fine for your use. ChatGPT also makes images.
Coding
Both can help. ChatGPT includes Codex. Grok's Premium plan and higher include Cursor Pro benefits. See Codex vs Claude Code to compare coding agents.
Should You Pay for Both?
Most people should not. Use both free plans for a week. Then pay for the one you kept opening, and only if you hit its limits.
Paying for both main plans costs $50 a month. If you need one paid plan for study or general work, start with ChatGPT Plus at $20. Pay for Grok Premium at $30 if X search, Imagine or Grok Bot are the reason you are paying.
