What this reference supports

DeepSeek R1 is a reasoning-focused model built from DeepSeek V3 foundations, published with model artifacts, technical documentation, and hosted API access, positioned for mathematics, coding, and deliberate multi-step reasoning tasks, and available through either DeepSeek's own hosted API or self-managed deployment of the released weights.

Use this page to compare the full R1 model against its smaller distilled variants and other reasoning models, and to check mathematics and coding benchmark evidence — such as AIME 2024 and LiveCodeBench — before choosing it for a reasoning-heavy workload, keeping in mind that distilled variants trade reasoning depth for lower serving cost.

Architecture, license ancestry, and behavior differ meaningfully between the full R1 model and its distills — use the exact artifact your evaluation targets, and budget for the repetition, readability, and language-mixing failure modes documented in DeepSeek's own official repository, plus the longer output length and higher token cost reasoning traces typically require.

Benchmark & Evaluation

ModelRefs currently has partial, narrow benchmark coverage for DeepSeek R1. Treat the available benchmark evidence as one input to the decision, not a guarantee that DeepSeek R1 is the strongest option for your workload, and evaluate it on representative workloads before selecting it.

  • Provider-reported benchmark results should be interpreted with methodology, dataset, prompting, tool, sampling, and recency limitations in mind.
  • The official repository reports evaluation settings and scores; this profile links them without copying new numbers.

Implementation considerations

  • Use the exact R1 or distill artifact and follow its prompt and sampling guidance.
  • Budget for long reasoning output, latency, serving resources, verification, and language-mixing or repetition failure modes.
  • Official artifacts support self-managed use under the documented licenses.
  • DeepSeek's hosted API is a separate service with mutable model mapping and terms.

Risks and limitations

  • The official repository documents possible repetition, readability, and language-mixing failure modes.
  • Model artifacts do not provide a managed production service; operators own serving, security, monitoring, evaluation, and incident response.
  • Quantization, prompt templates, runtime versions, hardware, and fine-tuning can materially change observed behavior.

Source coverage

This reference is Provisional. Model behavior, access, pricing, limits, and lifecycle can change; verify the linked provider documentation and run task-specific evaluations before implementation.

Known coverage gaps:

  • Hosted service data-control and regional evidence is incomplete.
  • Independent reproduction across serving stacks is not attached.
