GPT-5.4 vs Command R+Which is better in 2026?

Comparing GPT-5.4 and Command R+ across benchmarks, pricing, and capabilities.

Verdict: GPT-5.4 vs Command R+ — which is better?

GPT-5.4 (by OpenAI) and Command R+ (by Cohere) are two of the AI models people compare most. Here is how they stack up on benchmarks, price and capabilities, and which one to pick in 2026.

On price, Command R+ is roughly 12.9x cheaper per token on a blended 3:1 input/output basis, which adds up quickly at production volume.

GPT-5.4 also accepts a larger context window (1,000,000 input tokens), making it the stronger choice for long documents and large codebases.

Choose GPT-5.4 if…

  • you process long inputs — it offers a 1,000,000 token context window
  • you want the most recent training data — it shipped Mar 2026

Choose Command R+ if…

  • cost matters — it's about 12.9x cheaper per token
  • you need open weights you can self-host or fine-tune
