AI Model Comparison
Side-by-side comparison of pricing, context window, benchmarks, capabilities, and license. Every figure comes from the developer's own pages, last checked on ; each model's page lists its sources. A figure we could not source shows as a dash.
Model A — Cohere
Command R+ is a 104B-parameter language model from Cohere, announced on April 4, 2024 for enterprise retrieval-augmented generation (RAG) workloads. Its weights are published for non-commercial use.
Model B — OpenAI
GPT-4o is a multimodal model from OpenAI, first released on May 13, 2024 (snapshot gpt-4o-2024-05-13, which OpenAI shuts down in the API on October 23, 2026). In the API it takes text and image input and returns text.

Bold green values indicate the winner on that dimension where comparison is meaningful (lower price wins; bigger context wins; more open license wins; newer date wins). Prices are the ones each developer lists today; a model it no longer prices has none.
