Why DeepSeek-R1 fits this task
Three things about DeepSeek-R1 that map directly onto what this task rewards: Open-weight reasoning model on par with o1; Cheap reasoning per token. Beyond the task-specific fit, DeepSeek-R1 also brings mit license, both of which compound when the workload broadens.
The criteria this task rewards
LLMDex ranks best llm for math on 5 criteria , these are the axes the ranking uses, in priority order:
- MATH-500, AIME, USAMO, Putnam scores
- Step-by-step reasoning quality (not just final answer)
- Symbolic vs. numerical handling
- Tool-use for code-execution / Wolfram integration
- Latency on reasoning models, math thinking is slow
How DeepSeek-R1 scores on each axis
Where DeepSeek-R1 costs you: slow, reasoning is slow by design. For most teams this is acceptable on this workload, the value of the strengths above outweighs the cost. For cost-bound workloads or teams with strict latency budgets, run an eval against the next two ranked models on real data before committing.
Strengths that pay off here
- Open-weight reasoning model on par with o1
- MIT license
- Cheap reasoning per token
Tracked weaknesses
- Slow, reasoning is slow by design
- No vision
When to pick something else
If you can pay slightly more or accept slightly different tradeoffs, Claude Opus 4.7 from Anthropic ranks one position higher and tends to win on the hardest cases. Anthropic's mid-2026 flagship, ahead on SWE-bench, agent reliability, and writing quality.

Frequently asked
Is DeepSeek-R1 good for math?
DeepSeek-R1 is ranked #4 on LLMDex's math list. First open-weight reasoning model to match o1, the release that proved RL-from-scratch reasoning training was reproducible.How much does DeepSeek-R1 cost for math?
DeepSeek-R1 costs $0.55 / 1M tokens for input tokens and $2.19 / 1M tokens for output tokens. For math workloads, output costs typically dominate; budget on the higher number.What's a cheaper alternative to DeepSeek-R1 for math?
The next ranked model on this task is o4. Compare both before committing.When should I NOT use DeepSeek-R1 for math?
Tracked weakness: Slow, reasoning is slow by design. If that constraint is binding for your workload, the next-ranked model on this task is the safer pick.
