Free AI options for students
Most major AI models offer a free tier. ChatGPT Free (GPT-4o mini), Claude.ai Free (limited messages), and Gemini Free are the best starting points. For heavy daily use, Claude Pro or ChatGPT Plus at $20/month is worth it if you can afford it.
AI for math and STEM
OpenAI's o1 model scores 96.4% on MATH benchmarks — by far the best for advanced maths, physics, and engineering problems. For everyday homework, GPT-4o and Claude Sonnet both handle calculus, statistics, and chemistry well.
Using AI without academic dishonesty
Use AI to understand concepts, check your reasoning, and get feedback on drafts — not to generate submissions wholesale. Claude is particularly good at explaining WHY an answer is correct rather than just giving you the answer.
