What the RTX A4000 is good for
Moderate Language Model Inference
Run quantized or medium-sized language models using Ollama or vLLM within the 16 GB VRAM capacity.
Image Generation Workflows
Deploy ComfyUI templates for diffusion-based image generation and experimentation backed by about 372 GB/s of memory bandwidth.
Deep Learning Prototyping
Develop and test PyTorch/CUDA training scripts on an Ampere workstation architecture with compute capability 8.6.
Workstation Rendering Tasks
Execute rendering and simulation workloads that benefit from about 20.6 TFLOPS of single-precision performance.
Is it the right GPU for you?
The RTX A4000 suits developers and creators who need a reliable 16 GB Ampere workstation GPU for inference, image generation, and code prototyping. Choose a smaller GPU for basic testing with lower memory needs, or step up to a larger datacenter or workstation card if your models exceed 16 GB of VRAM or require higher memory bandwidth.

Frequently asked questions
Is the RTX A4000 suitable for LLM inference and fine-tuning?
With 16 GB of VRAM and about 372 GB/s of memory bandwidth, it handles inference for smaller or quantized language models via Ollama or vLLM, as well as lightweight fine-tuning. For full-parameter fine-tuning or running larger unquantized models, a GPU with more VRAM is recommended.
How does this GPU compare to larger or smaller options?
As a 16 GB workstation card offering about 20.6 TFLOPS of single-precision compute, the RTX A4000 sits between entry-level consumer cards and heavier workstation or datacenter GPUs. Stepping down reduces available memory for batch sizes, while stepping up provides greater VRAM capacity and memory bandwidth for heavier workloads.
What software environments are available for the RTX A4000 on ONIE?
You can deploy ready templates including PyTorch/CUDA, vLLM, Ollama, and ComfyUI, all compatible with the card's compute capability 8.6. Full SSH access is also provided so you can customize your environment.
How does billing work when renting the RTX A4000?
Rentals on ONIE use per-hour billing, allowing you to pay only for the time your instance is active.
