If you've been hearing about OpenAI o1-preview's math capabilities and wondering whether it's actually useful for you as a student in India — or just another overhyped AI announcement — this is worth reading. Because the numbers here are real, and they're pretty striking.
Let me put the headline stat out there first: in a qualifying exam for the International Mathematics Olympiad, GPT-4o solved only 13% of problems. The o1-preview model solved 83%. That's not a marginal improvement. That's a completely different tier of performance.
What makes o1-preview different from regular ChatGPT
Most AI models, including earlier versions of ChatGPT, respond fast. They generate text quickly by predicting the next word. o1-preview does something different: it actually "thinks" before answering. OpenAI trained it to spend more time reasoning through problems, trying different approaches, catching its own mistakes, refining its chain of thought, before giving you a response.
Think of it like the difference between a student who immediately writes down the first thing that comes to mind versus one who reads the problem twice, works through a rough draft, and then writes the final answer. o1-preview is the second type.
This approach is called "test-time compute" — giving the model more time to think during inference rather than just during training. And it turns out this makes a massive difference for math and science problems specifically.
The actual benchmark numbers (and what they mean for students)
A peer-reviewed study published in Nature Scientific Reports compared o1-preview's performance against humans across multiple cognitive domains. The results were surprisingly lopsided:
- Critical thinking (EWCTET test): o1-preview scored 24.33 vs undergraduate average of 13.8 and postgraduate average of 18.39
- Logical reasoning (LogiQA): 90% accuracy vs human average of 86%
- Scientific reasoning (TOSLS): 0.99 near-perfect score vs highest human score of 0.85
- Data literacy: 8.60 vs human post-test mean of 4.17
For math specifically, OpenAI's own evaluation on the 2024 AIME exam (which is designed to challenge the best high school math students in the US) showed o1 averaging 74% with a single attempt per problem, jumping to 83% with 64 samples, and hitting 93% with a learned scoring function across 1000 samples. A score of 13.9 problems out of 15 would place it in the top 500 students nationally in the US Mathematical Olympiad qualifying round.
For JEE-level problems and competitive math in India, this level of reasoning ability is genuinely useful. It can work through calculus, coordinate geometry, probability, and number theory problems with the kind of step-by-step reasoning that actually helps you understand the solution, not just get the answer.
"In our tests, the next model update performs similarly to PhD students on challenging benchmark tasks in physics, chemistry, and biology. We also found that it excels in math and coding. In a qualifying exam for the International Mathematics Olympiad, GPT-4o correctly solved only 13% of problems, while the reasoning model scored 83%." — OpenAI, September 2024
How Indian students can access o1-preview in 2026
This is where things get slightly less exciting, but still manageable. Here's the situation as of September 2026:
ChatGPT Plus (paid): The most straightforward way. ChatGPT Plus costs around ₹1,650 per month (approximately $20 USD) and gives you access to o1-preview and o1-mini. You can sign up at chat.openai.com and pay using an Indian debit card or credit card — UPI doesn't work directly, but some users have had success using cards linked to their UPI accounts or through virtual card services like Niyo Global.
o1-mini (free tier): India Today reported in 2024 that o1-mini was made available to free users. The free tier access has changed several times since then, so check the current ChatGPT interface — there's often a model selector dropdown where you can switch between GPT-4o and o1-mini. The mini version is faster and cheaper but still strong for math.
Rate limits: When o1-preview launched, OpenAI set limits at 50 queries per week for o1-preview and 50 queries per day for o1-mini on the Plus plan. These limits may have changed in 2026 — check your account settings for current quotas.
Microsoft Azure (for developers): If you're a student or developer working on a project, Microsoft Azure provides access to o1 models for enterprise and API use. College students with a .edu email can often get free Azure credits through Microsoft Azure for Students, which might be worth exploring if you need programmatic access.
What it's actually good at (and where it struggles)
Honestly, it's not perfect for everything. The Nature study specifically noted that "while o1-preview excelled in structured tasks, it showed limitations in problem-solving and adaptive reasoning." What that means in practice: give it a well-defined math problem with a clear structure, and it's excellent. Ask it to reason about an ambiguous real-world situation, and it can stumble.
For Indian students, here's where it genuinely shines:
- JEE Main and Advanced math problems — algebra, calculus, probability, vectors
- CBSE and ICSE board exam preparation, especially for Class 11 and 12 maths
- Understanding derivations and proofs step by step
- Competitive exam prep for KVPY, RMO (Regional Math Olympiad), and similar
- Engineering college coursework — differential equations, linear algebra, numerical methods
Where it's less useful:
- Problems that require drawing diagrams or interpreting geometric figures (though this is improving)
- Quickly answering simple questions — GPT-4o is faster for that
- Real-time information (it doesn't browse the web unless you use it within ChatGPT with browsing enabled)
(I tried using it for a few integration problems last month, and it was genuinely impressive — it didn't just give the answer, it walked through substitution choices and explained why each step worked. Which is actually more useful for learning than just seeing a solution.)
Comparing your options: o1-preview vs other AI tools for math
| Tool | Math strength | India access | Cost | Best for |
|---|---|---|---|---|
| o1-preview | Excellent | ChatGPT Plus | ~₹1,650/month | Hard problems, JEE, competitive math |
| o1-mini | Good | Free + Plus | Free or ₹1,650/month | Everyday student use, CBSE prep |
| GPT-4o | Moderate | Free + Plus | Free tier available | Quick answers, explanations |
| Gemini 1.5 Pro | Moderate | Good in India | Free tier available | Google Workspace users |

Practical tips for Indian students using o1-preview
A few things that actually help:
Type out the full problem clearly. Don't abbreviate or use shorthand. The model reasons better when the input is unambiguous.
Ask it to explain its reasoning, not just give the answer. Something like "Solve this step by step and explain why each step works" gives you something you can actually learn from, which is the whole point.
For photo-based problems (textbook pages, question papers), use ChatGPT's image upload feature with GPT-4o first to get the text out, then paste into o1-preview. (I know, sounds like extra work — but image recognition in o1 models has historically lagged behind the reasoning side.)
Don't treat it as a calculator. It's better used as a tutor who walks you through method and approach. For pure calculation speed, WolframAlpha is still hard to beat.
And if you're interested in how other AI companies are competing in the math reasoning space, xAI's Grok math solver and its India access situation is worth reading alongside this.
Should you pay ₹1,650 a month for this?
For most students, my honest take: probably not as a standalone subscription. Try o1-mini for free first and see if it covers your needs. If you're doing JEE Advanced prep or competitive math at a serious level, the Plus subscription might be worth it for a month or two during intensive study periods — but don't commit to it long-term just for math help.
If your college gives you access to Microsoft tools, check whether your institution has an Azure or OpenAI education tie-up. Some IITs and NITs have started offering this. Worth asking your college's IT department.

One thing is clear: the gap between "AI that can do math" and "AI that can reason through math" is real, and o1-preview sits firmly in the second category. For students who've been frustrated by AI tools that confidently give wrong answers, this is a meaningful step up. It's not magic. But it's genuinely useful in a way that earlier models weren't.
