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 — Moonshot AI
Kimi K3.1 Pro is the first model of Moonshot AI's K3.1 series, launched on October 23, 2026 with a 1M-token context window and a faster Highspeed variant. Moonshot says its full weights will be released by November 4, 2026; until then it is offered only through Kimi's apps and API.

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.
