| Price basis | — | Cohere's list price for Command A, read 2026-08-22 on the first-party model card at docs.cohere.com/docs/command-a: Input $2.5 / 1M tokens, Output $10 / 1M tokens, printed beside the 256,000-token context window and the model ID command-a-03-2025 that this row carries. We cite that page rather than cohere.com/pricing because Cohere's public rate card no longer prices Command A at all: with all four of its tabs opened, the "Generative models" tab prices only Command A+ ($0 / Free under Apache 2.0 — a different, open-weights SKU), Command R ($0.15 / $0.60) and Command R7B ($0.0375 / $0.15). The rate card's legacy "For existing customers" block does print $2.50/$10, but for Command R+ 08-2024 — the same two figures as this row, which is a coincidence and not a source for it. Command A itself is current, not withdrawn: docs.cohere.com/docs/models lists command-a-03-2025 with status Live. |
