Aya Expanse 32B needs ~17.7 GB VRAM. RTX A4000 16GB has 16.0 GB. With Q2_K quantization, expect ~14 tok/s.
Operating mode
Interactive favors responsiveness, while light API and scale-out lean harder on serving readiness. The fit stays the same, but the recommendation lens changes.
Current mode
Balanced
Balanced for general local use. Keeps the ranking neutral across personal and serving workflows.

Offload
40%
It fits through host-memory offload, and offload is the main reason performance drops.
CPU or host-memory offload is active
About 10% of the working set spills out of accelerator memory, which usually hurts latency and sustained decode throughput.
Very little memory headroom
You can run the model, but there is not much room left for longer context, bigger batches, extra apps, or future model updates.
Remove offload with more accelerator memory
Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.
Increase host RAM if you keep offloading
This setup may need roughly 1.2 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Yes, RTX A4000 16GB can run Aya Expanse 32B at Q2_K quantization (Very compromised (needs ~1.2 GB host RAM)). The recommended Q4_K_M requires 24.8 GB which exceeds available memory, but at Q2_K it needs only 17.7 GB. Expected decode speed: 14.0 tok/s.
Aya Expanse 32B (32B parameters) requires approximately 24.8 GB at Q4_K_M quantization. On RTX A4000 16GB, it fits at Q2_K using 17.7 GB.
The recommended quantization is Q4_K_M, but on RTX A4000 16GB the best fitting quantization is Q2_K, which uses 17.7 GB.
On RTX A4000 16GB, Aya Expanse 32B achieves approximately 14.0 tokens per second decode speed with a time-to-first-token of 13780ms using Q2_K quantization.
For coding workloads, Aya Expanse 32B on RTX A4000 16GB receives a F grade with 5.2 tok/s and 4K context.
On RTX A4000 16GB, Aya Expanse 32B can safely use up to 5K tokens of context at Q2_K quantization. The model's official context limit is 8K, but available memory constrains the safe maximum.
