How Grok AI and ChatGPT’s Deep Research handle their limit usage and pricing
Here’s where similarities show more. These two platforms couldn’t be more different in how they let you use their research features.
Grok AI’s approach is this: You pay for a subscription and use DeepSearch and other answer models, such as Fast, Expert, Auto, etc., as much as you want. There are no counting tasks, monthly limits, or running out halfway through an important research project.
ChatGPT goes the opposite route: Everything is measured and counted. You get a specific number of research tasks each month, and when they’re gone, you either wait or get reshuffled to a lighter version. It is just like wifi or airtime. There is how much each AI costs:
Grok AI
- Basic (Free Plan):
- Limited access to the Grok 3 model only
- No access to Grok 4’s advanced DeepSearch capabilities
- Basic search functionality with reduced performance
- SuperGrok ($300/year or $30/month):
- Full access to Grok 4 with integrated DeepSearch
- Replaces Grok 3 Think functionality with enhanced reasoning
- 128,000 token context memory for comprehensive research
- Voice with vision capabilities
- Unlimited usage within fair use policies
- SuperGrok Heavy ($3,000/year or $300/month):
- Access to Grok 4 Heavy before everyone else
- Double the context memory (256,000 tokens), which is perfect for handling massive research projects
- First to try new features when they launch
- Faster processing speeds and better performance, total package
ChatGPT Deep Research usage limits
- Free Plan Users:
- 5 Deep Research tasks per month using the lightweight version only
- No access to the standard, more robust model
- Suitable for basic research needs with limited complexity
- Plus, Team, Enterprise, and Edu Plans:
- 10 standard model tasks per month (full capability)
- 15 additional lightweight tasks after the standard quota is exhausted
- Total: 25 research tasks per month
- Automatic switching between models maintains workflow continuity
- Pro Plan Users:
- 125 standard model tasks per month (maximum capability)
- 125 additional lightweight tasks for extended usage
- Total: 250 research tasks per month
- Highest tier access with substantial research capacity
Which subscription gives more for less?
Suppose you’re just getting started or need occasional help. In that case, ChatGPT’s free tier gives you 5 research tasks monthly, which beats Grok’s free version that only offers basic Grok 3 access without the advanced research capabilities you actually want.
If you do research regularly but don’t want to break the bank, this is where you might get caught in a decision-making web. ChatGPT Plus at $20/month gives you 25 research tasks total, while Grok’s SuperGrok at $30/month lets you research unlimited times with better context memory. If you ask me, that extra $10 might be worth it if you tend to research excessively.
If you’re a research-heavy user who can’t afford interruptions, ChatGPT Pro costs $200/month for 250 tasks. Still, Grok’s SuperGrok Heavy at $300/month gives you unlimited access to their most advanced model with double the context memory. Plus, you get first access to new features as they roll out.
So, the subscription that gives more depends on whether you prefer knowing exactly how much you can use each month (ChatGPT deep research) or never having to think about limits (Grok AI).
Before revealing the testing results, sharing the method behind the comparison is essential. This will give you a clear picture of how I tested both tools.
The criteria i used in evaluating Grok AI and ChatGPT Deep Research
To make a balanced comparison between these two AI research tools, I tested both platforms using three different prompts.
1. OPPO vs Samsung (Opinion Piece)
- Write an in-depth opinion article comparing which Android brand —OPPO or Samsung — currently offers the most enjoyable overall user experience. Evaluate design, camera quality, performance, software features, ecosystem, and value for money, using examples from their latest flagship and mid-range models. Present a reasoned conclusion on which brand provides the better experience, supported by factual points but written in a personal, opinion-based tone.
2. EU AI Act 2025 (Research Summary)
- Summarize the 2025 EU AI Act in clear, concise language, focusing on its main provisions, objectives, and impact on AI developers, businesses, and users. Use only up-to-date and credible sources from government websites, reputable news outlets, and expert analysis, and cite each source properly.
3. Trend-focused Research
- Gather and summarize the latest developments in the current season of Big Brother Naija from the last 2 weeks, including trending topics on X (Twitter), Instagram, and entertainment news sites. Highlight the most talked-about housemates, notable events, and public sentiment, with proper citations from each source.
With them, I could see how each one performs in actual research situations, gauging with six criteria rather than just comparing features.
Here’s what I looked for and why each factor matters:
Speed
Time is important when I’m researching, so I timed how long each platform took to give me complete answers. When exploring a topic, I often need to ask follow-up questions quickly. Slower responses can interrupt my thinking flow and make the research process feel sluggish.
Accuracy
I verified the accuracy of the information by comparing the claims against reliable sources. This was important because both tools can sound very confident even when wrong. I looked at basic facts and tested how well they handled the prompts where answers weren’t black and white.
Citation Quality
When researching, citations are just as important as the topic itself because, without proper sources, you might as well be taking information from word of mouth. I examined whether each platform provided sources and whether those sources were legitimate and current.
Relevance
Sometimes, AI provides a lot of information that doesn’t actually answer your question. I looked for how each platform understood what I was asking and stayed focused on my research needs instead of providing related but unhelpful information.
Depth
Basic information is available everywhere. What makes these tools valuable is their ability to thoroughly analyze complex topics. I tested whether each platform could move beyond surface-level answers and consider different angles on issues.
Interface Usability
When a tool feels frustrating to use, I might leave it behind at some point, even if it works well. I evaluated how easy each platform was to navigate, whether responses were clearly presented, and how well they handled my follow-up questions. Minor issues can add up during longer research sessions.
These six areas gave me a complete understanding of what it is like to use these platforms for research.

10 Frequently Asked Questions about Grok AI vs ChatGPT Deep Research
1. What’s the actual difference between Grok AI and ChatGPT Deep Research?
- Both features let AI explore in-depth topics and provide comprehensive research, but they work differently. Grok AI is built into the Grok 4 model and works more like an enhanced thinking process. It can access real-time information and reason through complex topics with massive context memory. ChatGPT’s Deep Research, on the other hand, is a separate feature that creates detailed research reports by breaking down your query into smaller questions and systematically investigating each part.
2. Can I use these features for free?
- With ChatGPT, yes, you get 5 Deep Research tasks monthly on the free plan, though you’ll only have access to the lightweight version. With Grok AI, the free tier only gives you basic Grok 3 access, so you won’t get the advanced DeepSearch capabilities that come with Grok 4. You’ll need to upgrade if you want to try Grok’s research features.
3. What happens when I hit my ChatGPT research limit?
- Once you use up your standard model tasks, ChatGPT automatically switches to the lightweight version if you have those remaining. If you’ve used everything up, you’ll have to wait until next month or upgrade your plan. The system won’t just cut you off mid-research – it’ll let you know when you’re running low.
4. Does Grok AI really have unlimited research usage?
- On paid plans, yes. Once you subscribe to SuperGrok or SuperGrok Heavy, there’s no monthly task counter ticking down. You can research as much as you want within their fair use policies. This makes it great if you’re the type who goes down research rabbit holes or needs to do extensive investigation work.
5. Which one gives more accurate and up-to-date information?
- Both can access current information, but they handle it differently. Grok AI integrates real-time data directly into its responses, while ChatGPT’s Deep Research systematically searches and verifies information from multiple sources before compiling it into a report. Both should perform well for breaking news or recent events, but ChatGPT’s methodical approach might catch more nuanced details.
6. Can I use these features for academic research?
- Absolutely, but remember that both are AI tools and should supplement, not replace, proper academic research. ChatGPT’s Deep Research is particularly good for academic work because it provides structured reports with clear methodology. Grok’s DeepSearch is better for exploratory research and brainstorming. Always verify important claims with primary sources.
7. What’s the context memory difference, and why does it matter?
- Grok’s SuperGrok handles 128,000 tokens, while SuperGrok Heavy manages 256,000 tokens. ChatGPT’s context varies by model but is generally smaller. More context memory means the AI can remember and work with much larger amounts of information in a single session – think of it like having a bigger desk to spread out all your research materials.
8. Is the lightweight version of ChatGPT’s Deep Research worth using?
- The lightweight version is still quite capable – it’s not like getting a watered-down product. It just uses a slightly less powerful model, so responses might be slightly less detailed or take shortcuts in reasoning. You probably won’t notice much difference for many research tasks, especially if you’re just getting background information on a topic.
9. Which platform is better for business research?
- It depends on your needs. Grok’s unlimited approach makes more sense if you do frequent, ongoing research and can’t afford to be limited by monthly quotas. ChatGPT’s Deep Research might be better if you do periodic deep dives and want structured, methodical reports. ChatGPT offers dedicated business plans for enterprises, while Grok currently has more of a consumer focus.
10. Can I get refunds if I don’t like the research quality?
- Both platforms have different refund policies, so check their terms of service. Generally, it’s worth trying the free tiers first to get a feel for the research quality. ChatGPT’s free plan gives you actual Deep Research tasks to test, while Grok’s free tier won’t let you experience DeepSearch, so you’ll need to rely on trial periods if available or their money-back guarantees.
