Choose the Cortex AI for local inference and everyday assistant use, the AI Pro X — this build — for RAG pipelines, diffusion work and light fine-tuning, the AI Ultra for single-GPU 30B-class fine-tuning, and the AI Ultimate when you need multi-GPU training or 70B+ model serving. Not sure? Call us on 0207 096 5008 and we'll match a build to your framework and model size.

As a rough guide, the RTX 5080’s 16GB comfortably runs quantised 7B–13B models at full context length, and handles SDXL and Flux generation plus LoRA fine-tuning without dropping into low-VRAM mode. Context length and quantisation both change the maths, so tell us your target and we'll size it precisely.

Yes. Every Cortex AI ships with NVIDIA's data-science driver stack, with CUDA and cuDNN version-matched to PyTorch and validated against a live test job before dispatch, so you're training on arrival rather than untangling version mismatches.

Yes. We supply Cortex AI workstations with Windows 11, Ubuntu LTS, or a dual-boot configuration, with the CUDA stack installed and validated on whichever you choose.

Yes. The X870E board and North XL chassis leave room to expand, though a second flagship card will usually want a larger power supply than the 1000W fitted as standard. Tell us if multi-GPU is on your roadmap and we'll specify the PSU for it up front.

Yes — every Cortex AI workstation is fully customisable. We can adjust GPU, memory, storage and cooling to suit your exact model size and budget before we build.
