DOC:002 // THE CASE FOR LOCAL INFERENCE

Why Local
Changes Everything

Cloud AI is convenient until it isn't. Privacy, cost, speed, control — every serious AI deployment eventually hits the limits of outsourced inference. Here's the full picture.

PER-TOKEN FEES
$0
After the hardware is paid for, every extra token costs only electricity
TIME TO FIRST TOKEN
84ms
Typical TTFT for a model that fits in VRAM on an RTX 4090. No network hop.
DATA EGRESS
0bytes
Zero data leaves your infrastructure. Prompts, context, outputs — all local
UPTIME CONTROL
100%
No provider outages, no rate limits, no API deprecation notices at 3am
THE CASE

Six Reasons
That Actually Matter

These aren't theoretical advantages. Each one maps to a real failure mode of cloud AI that organisations hit as their usage scales — or the moment they process their first sensitive document.

PRIVACY

Zero Data Egress

Your prompts, documents, and outputs never leave your network. No third-party eyes. No training on your data. No accidental logging of confidential queries.

  • Prompts never touch external servers
  • GDPR-compliant by architecture, not policy
  • No vendor data retention clauses to worry about
  • Audit logs stay in your own infrastructure

01
COST

No Per-Token Tax

API bills compound brutally at scale. A few dollars per million tokens sounds cheap until you're running millions of queries a day. Local inference trades variable cost for fixed infrastructure.

  • Heavy users can pay off the hardware in months
  • Unlimited internal usage after hardware cost
  • No surprise invoices from burst traffic
  • Run batches overnight at zero marginal cost

02
CONTROL

No Rate Limits

Burst to thousands of requests per second. Run inference 24/7 with no throttling, no quota exhaustion, no provider-side degradation affecting your production systems.

  • Concurrent requests limited only by your GPU
  • No TPM/RPM caps to architect around
  • Guaranteed availability — you own the stack
  • Scale horizontally on your own schedule

03
LATENCY

Sub-100ms TTFT

First token in milliseconds, not seconds. Local inference eliminates the network round-trip to US datacenters. Streaming feels instant on properly configured hardware.

  • Sub-100ms TTFT on an RTX 4090 for models that fit in VRAM
  • No geographic latency to US/EU API endpoints
  • Consistent performance under load
  • LAN-only path: application → inference server

CUSTOMISATION

Full Model Access

Closed APIs hand you a black box. Local deployment means you own every weight, every parameter. Fine-tune, merge, quantize, and audit exactly what your model does.

  • LoRA / QLoRA fine-tuning on your own data
  • Choose your quantisation level (Q4 → Q8 → FP16)
  • Merge specialist adapters at inference time
  • No model versioning surprises from your vendor

COMPLIANCE

Regulatory Ready

Industries with data residency requirements can finally use LLMs at scale. Healthcare, legal, finance — local deployment makes compliance the default, not an afterthought.

  • HIPAA: patient data never leaves your network
  • Attorney-client: privileged queries stay private
  • SOC2 / ISO27001: simpler evidence collection
  • EU AI Act: full model transparency and control

Local vs Cloud

A direct comparison across the dimensions that matter for production deployments.

Who Needs This Most

01
HEALTHCARE
Clinical AI Without Compromise

Patient records, clinical notes, imaging reports — none of it can touch an external API. Local LLMs enable document summarisation, ICD coding assistance, and clinical decision support with full data residency.

HIPAA NHS DSP TOOLKIT HL7 FHIR ISO 27799
02
LEGAL
Privileged Work Stays Privileged

Contract review, discovery, due diligence — attorney-client privilege doesn't survive sending documents to an OpenAI endpoint. Local RAG pipelines over case files, with zero external exposure.

ATTORNEY-CLIENT SRA COMPLIANCE GDPR ART.9
03
FINANCE
High-Volume Analysis On-Prem

Earnings call summarisation, risk report generation, customer communication at scale. Fixed infrastructure cost transforms the economics — 10M tokens a day costs the same as 100K.

SOC 2 TYPE II FCA COMPLIANCE PCI DSS

ENGINEERING
Code That Stays In-House

Proprietary codebases, internal tooling, IP-sensitive architectures. Local code completion and review with Qwen3-Coder or Devstral — your source code never leaves the building.

Common Questions

A single RTX 4090 or 3090 (24GB VRAM) runs today's best mid-size models, such as Qwen3 27B or Gemma 4 26B, at Q4, typically at 70–150 tokens/sec. A 16GB card runs gpt-oss-20b. 70B-class models need two 24GB GPUs or a Mac with 64GB+ unified memory. We assess your use case and recommend the minimum hardware that meets your throughput requirements. Existing servers with NVIDIA GPUs are often already sufficient.
For most production use cases — document processing, summarisation, RAG, code generation, customer support — modern open models match or exceed GPT-4 performance after proper fine-tuning on your domain. The gap has closed dramatically: as of June 2026, Gemma 4 31B ranks #3 among open models on the LMArena text leaderboard, and runs on a single high-end GPU. Where frontier models still lead is on novel reasoning tasks. We'll benchmark your specific workload before recommending a model.
That's exactly what Jonestech handles. We deploy an OpenAI-compatible API endpoint on your hardware — your existing applications swap one URL and one API key, and keep working. No model management, no GPU driver archaeology, no quantisation decisions. We handle the stack; you get the endpoint.
We offer managed deployment packages that include model updates, monitoring, and on-call support. Alternatively, we do a clean handover with full documentation for teams who want to self-manage. The stack (Ollama / vLLM + a gateway) is operationally simple once deployed — model swaps are typically a 10-minute operation.
Yes — and it's one of the strongest arguments for local deployment. Models ship as single files (GGUF format) that can be transferred via physical media or internal network. Once loaded, the inference server requires zero internet connectivity. We've deployed in environments with no external network access at all.
