Aya Expanse 32B — Hardware Requirements & GPU Compatibility

Chat

Aya Expanse 32B is Cohere Labs' 32.3-billion-parameter multilingual chat model, built on the Command-R model family and refined through data arbitrage, multilingual preference training, safety tuning, and model merging aimed at closing the performance gap between English and lower-resource languages. It is optimized to perform well across 23 languages including Arabic, Chinese, French, Hindi, Japanese, and Russian, and Cohere reported it outperforming much larger models such as Llama 3.1 405B and Mistral Large 2 on multilingual evaluation. At 32.3 billion parameters, it needs a high-end consumer GPU or multi-GPU setup once quantized. It is released under the CC BY-NC 4.0 license, restricting use to non-commercial purposes only, and was published in October 2024, as the 32B counterpart to the smaller Aya Expanse 8B model.

Can I run Aya Expanse 32B on a Mac?

Aya Expanse 32B requires at least 15.1 GB at Q2_K, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.

Can I run Aya Expanse 32B locally?

Yes — Aya Expanse 32B can run locally on consumer hardware. At Q4_K_M quantization it needs 21.3 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Aya Expanse 32B?

At Q4_K_M, Aya Expanse 32B can reach ~225 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~31 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = (bandwidth GB/s ÷ model GB) × efficiency

Example: NVIDIA B200 → 8000 ÷ 21.3 × 0.65 = ~244 tok/s
