Clear hardware plan before buying

Private model setup
Private AI models on hardware you control.
We design and configure private open-weight model infrastructure for companies that want local assistants, local speech models, private knowledge workflows, and tighter control over sensitive files.

Hardware guide
What private models can realistically run on.
Model size, quantization, context length, and response speed all change the hardware requirement. We scope the goal first, then choose a realistic private setup instead of overselling one machine for every use case.
Starter private node
Theoretical fitHardware
Mac mini M4/M4 Pro or small Linux mini PC with 24-64 GB unified/RAM memory.
Model class
Small open-weight LLMs around 0.5B-8B, compact embedding models, local STT, and lightweight TTS models in quantized form.
Best for
Private notes, simple assistant workflows, internal Q&A, summaries, small automations, voice transcription, and basic speech output.
Planning note
Good for privacy and utility, not for heavy reasoning or high-volume multi-user work.
Founder / team workstation
Theoretical fitHardware
Mac Studio 64-128 GB unified memory or NVIDIA workstation with 24-32 GB VRAM.
Model class
Mid-size open-weight LLMs around 14B-32B, coding models, major open-weight model families, and stronger speech pipelines depending on quantization.
Best for
Better coding help, richer private knowledge assistants, document analysis, local STT/TTS workflows, and higher quality internal automations.
Planning note
Can run strong local models, but speed and context size still depend on quantization and runtime tuning.
Production GPU server
Theoretical fitHardware
Single or multi-GPU server with RTX 4090/5090, RTX 6000 Ada, A6000, L40S, A100, or H100 class GPUs.
Model class
Larger 32B-72B class dense models, MoE models where active parameters fit memory, larger coding/reasoning models, and GPU-backed media inference.
Best for
Team access, private API endpoints, agent workflows, larger context windows, stronger latency targets, and heavier voice/media processing.
Planning note
Requires real deployment discipline: cooling, drivers, monitoring, backups, access control, and model evaluation.
Large-model lab
Theoretical fitHardware
Multi-GPU server or rented private cloud GPU capacity with 80 GB+ VRAM cards and fast storage.
Model class
Large open-weight MoE / flagship model families when memory, sharding, and serving stack are planned correctly.
Best for
Research, custom evaluation, private model comparison, heavier enterprise workflows, and specialized multimodal experiments.
Planning note
Usually not the first purchase. We validate business value with smaller models before recommending this tier.

Service FAQ
Questions before scoping Private AI Models.
What are private AI models?
Private AI models are model runtimes and workflows operated around company-controlled data, access rules, and infrastructure instead of only relying on public chat tools.
Does private AI always require a GPU server?
No. Some assistant, transcription, and knowledge workflows can start on a Mac mini or workstation. Heavier inference, image, and team workloads may need GPU hardware or cloud GPU capacity.
What does Nythral configure?
Nythral scopes hardware, model runtime, storage, access policy, backups, monitoring, workflows, and the handoff path for daily use.
Examples
Real surfaces and sample outputs.
Video, audio, infrastructure, and product surfaces are arranged as proof of the workflow, not decorative filler.

Private does not mean isolated from quality
A private model stack can use open-weight model families for sensitive work while still keeping a practical path to hosted frontier models when a task needs stronger reasoning.
We size the machine around the workflow
The right answer for a private assistant is different from the right answer for code agents, document search, voice transcription, or an internal API used by a team.
What Nythral configures
We prepare the runtime, model downloads, serving API, access rules, backups, update process, local speech services, and the assistant workflows that make the hardware useful.
Example private AI architecture
A practical setup usually has a model runtime, vector or file index, private storage, access rules, logging, backups, and optional cloud fallback for tasks that need frontier-model reasoning.
Local speech and consent-based media
For voice workflows, we can set up local speech-to-text and text-to-speech models so audio can be processed inside the private environment. For face replacement or synthetic media, we only scope consent-based, legally allowed workflows with clear rights to source material and obvious approval boundaries.
When private models make sense
Private models are strongest when the company has sensitive documents, repeatable internal work, or a founder who wants AI infrastructure they can control and improve over time.
