    Command R+ (08-2024) ships open weights (CC-BY-NC 4.0); GPT-5.5 is API-only.

It's a genuine coin-flip between Command R+ (08-2024) and GPT-5.5: 2 category wins each, with the rest tied. Command R+ (08-2024) publishes pricing ($10.00 / 1M output tokens) while GPT-5.5 does not. GPT-5.5 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+ (08-2024) handles text while GPT-5.5 handles text, vision, audio, which can be the deciding factor before you even look at benchmarks. Command R+ (08-2024) ships open weights (CC-BY-NC 4.0); GPT-5.5 is API-only.

GPT-5.5 is the newer of the two, released 18 months after Command R+ (08-2024), which usually means a more recent knowledge cutoff and updated safety post-training. Command R+ (08-2024) is usually picked for rag and data extraction workloads, while GPT-5.5 sees more deployments in agents and tool use. If pricing matters more than every last benchmark point, run the numbers in the calculator below before committing.

Pricing at scale

What you'd actually pay at typical workloads. Numbers come from each model's published per-million-token rates.

  • Light usage, 100k in / 50k out per day$22.50 vs ,
  • Heavy usage, 1M in / 500k out per day$225 vs ,
  • RAG workload, 5M in / 200k out per day$435 vs ,

Light usage, 100k in / 50k out per day: pricing not directly comparable (one or both models are missing public per-token rates). Heavy usage, 1M in / 500k out per day: pricing not directly comparable (one or both models are missing public per-token rates). RAG workload, 5M in / 200k out per day: pricing not directly comparable (one or both models are missing public per-token rates).
