Task-specific scoring for math workloads across 5 dimensions.
| Dimension | Claude Sonnet 4.5 | DeepSeek V3 | Edge |
|---|---|---|---|
| Step-by-step Reasoning | Clear, well-explained reasoning chains with each step justified. Rarely makes logical leaps. | Concise, accurate step-by-step solutions with strong logical rigor. Adept at breaking down complex multi-step problems. | |
| Symbolic Math | Handles algebraic manipulation and calculus competently. Can struggle with deeply nested symbolic expressions. | Excels at symbolic manipulation including integration, differentiation, and algebraic simplification with high accuracy. | |
| Word Problems | Strong at extracting mathematical structure from natural language. Careful to identify all constraints and edge cases. | Translates word problems to mathematical formulations efficiently. Particularly strong with optimization and rate-based problems. | |
| Statistical Analysis | Thorough statistical reasoning with appropriate caveats about assumptions and limitations. | Computes statistical measures accurately and efficiently. Slightly less thorough on assumption violations. | tie |
| Proof Construction | Constructs well-organized proofs with explicit justification at each step. Strong at proof by contradiction and induction. | Produces rigorous proofs with efficient notation. Handles number theory and combinatorial proofs with particular strength. | tie |
