C4ai Command R 08 2024 — Hardware Requirements & GPU Compatibility

ChatFunctions

C4AI Command R 08-2024 is Cohere Labs' (formerly Cohere For AI's) 32.3-billion-parameter chat model, an August 2024 refresh of the original Command R built for retrieval-augmented generation with citations, single-step tool use, and multi-step agentic tool use. It is an auto-regressive transformer using grouped-query attention for faster inference, trained and evaluated across a wide multilingual set including English, French, Spanish, German, Japanese, Korean, Arabic, and Simplified Chinese, among others. Cohere positions this release around stronger grounded RAG capability and broader multilingual coverage rather than a change in scale. At 32.3 billion parameters, it needs a high-end consumer GPU or a multi-GPU setup once quantized. Context length is 128,000 tokens. It is released under a Creative Commons Attribution-NonCommercial (CC BY-NC 4.0) license plus Cohere's Acceptable Use Policy, restricting the model to non-commercial use. It was published in August 2024.

Frequently Asked Questions

How much VRAM does C4ai Command R 08 2024 need?

C4ai Command R 08 2024 requires 21.3 GB of VRAM at Q4_K_M, or 71.0 GB at BF16.

VRAM = Weights + KV Cache + Overhead

Weights = 32.3B × 4.8 bits ÷ 8 = 19.4 GB

KV Cache + Overhead ≈ 1.9 GB (at 2K context + ~0.3 GB framework)

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.
