Verdict by category
  • PriceGPT-5 nano

    GPT-5 nano is roughly 3.8× cheaper on output tokens ($0.40 vs $1.50 per 1M).

  • Context windowGPT-5 nano

    GPT-5 nano accepts 400K tokens vs 128K, 3.1× the room for long documents and codebases.

  • BenchmarksTie

    No directly comparable public benchmarks are available for both models, check the spec sheets for individual scores.

  • ModalitiesGPT-5 nano

    GPT-5 nano supports 2 modalities (text, vision) vs 1 for Command R.

  • OpennessCommand R

    Command R ships open weights (CC-BY-NC 4.0); GPT-5 nano is API-only.

On balance GPT-5 nano edges ahead, winning 3 of 5 categories against Command R's 1. GPT-5 nano is roughly 3.8× cheaper on output tokens ($0.40 vs $1.50 per 1M). GPT-5 nano accepts 400K tokens vs 128K, 3.1× the room for long documents and codebases.

No directly comparable public benchmarks are available for both models, check the spec sheets for individual scores. They differ in modality coverage, Command R handles text while GPT-5 nano handles text, vision, which can be the deciding factor before you even look at benchmarks. Command R ships open weights (CC-BY-NC 4.0); GPT-5 nano is API-only.

GPT-5 nano is the newer of the two, released 17 months after Command R, which usually means a more recent knowledge cutoff and updated safety post-training. Command R is usually picked for rag and customer support workloads, while GPT-5 nano sees more deployments in cheapest llm and fastest llm. If pricing matters more than every last benchmark point, run the numbers in the calculator below before committing.
