Our recommendation

DeepSeek V3 is the best model for pure mathematical reasoning, especially for competition-level and proof-based problems. For math education and tutoring, Claude Sonnet 4.5 offers the clearest step-by-step explanations. The quality gap between models is largest on hard problems - for standard calculus or algebra, most frontier models perform similarly.

Common questions

Which AI is best at solving complex math problems?

DeepSeek V3 leads on competition-level and proof-based math. It consistently outperforms GPT-5.2 and Claude on benchmarks like MATH and GSM8K, while costing significantly less per query.

How do I test which LLM handles my math use case best?

Send the same problem to multiple models and compare their step-by-step solutions. Check for correctness at each step, not just the final answer - models sometimes get the right answer through wrong reasoning. Pay attention to how they handle edge cases and whether they state assumptions clearly.

Can LLMs reliably verify mathematical proofs?

DeepSeek V3 and Claude Sonnet 4.5 can verify many standard proofs and identify logical gaps. However, for research-level mathematics, AI proof verification should be treated as a helpful assistant rather than a definitive oracle.

What is the best LLM for math in 2026?

DeepSeek V3 is the best LLM for pure mathematical reasoning in 2026, consistently outperforming competitors on competition-level problems and formal proofs. For math tutoring and clear step-by-step explanations, Claude Sonnet 4.5 is the top choice. LLMWise gives you access to both through a single API.
