Private LLM Inference
for Regulated Industries

How RO2 Labs delivers Llama 3 70B inference with zero third-party data routing on single-tenant hardware.

The Problem

Large language models are transforming how organizations process documents, generate analysis, and accelerate decision-making. But most LLM APIs are built for speed and scale, not for data control.

When you send a prompt to a typical cloud LLM provider, your data travels through shared GPU clusters, crosses multiple network boundaries, and may be logged, cached, or retained by third-party sub-processors. For organizations in defense, healthcare, finance, or legal, this creates data handling risk that no terms-of-service agreement can fully address.

The core issue is architectural. Shared infrastructure means shared risk.

Our Approach

RO2 Labs runs Llama 3 70B on dedicated Apple Silicon hardware in Austin, TX. The inference environment is single-tenant. No other customer workloads, no shared GPU pools, no multi-hop data routing.

Your Application

TLS via Cloudflare Tunnel

Auth Proxy (API key validation, rate limiting)

Ollama / Llama 3 70B on M3 Ultra
96 GB unified memory · 60-core GPU · Austin, TX

The API is fully OpenAI-compatible. Organizations already using the OpenAI SDK can switch by changing a single base URL. No code rewrite, no new client library, no retraining required.

Data Flow

Every request follows the same path:

  1. Client sends HTTPS request to llm.ro2-labs.ai
  2. Cloudflare Tunnel terminates TLS and forwards to the local auth proxy
  3. Auth proxy validates the API key and checks rate limits
  4. Request is forwarded to Ollama running Llama 3 70B on local hardware
  5. Response is returned to the client with data residency headers

At no point does the prompt or response content leave the physical hardware in Austin, TX. There are no third-party inference providers, no GPU rental pools, and no telemetry exports.

Verifiable Residency

Every API response includes machine-readable headers confirming where inference was performed and whether any third-party routing occurred:

{
  "model": "llama3:70b",
  "choices": [{ "message": { "role": "assistant", "content": "..." } }],
  "x-ro2-data-residency": "on-prem-austin-tx",
  "x-ro2-third-party-routing": "none"
}

These headers provide an auditable record for compliance teams reviewing data handling practices.

How Our Infrastructure Supports Regulated Workloads

The table below describes common data handling concerns in regulated industries and the architectural properties of our infrastructure that address them. RO2 Labs provides infrastructure controls. Compliance is a shared responsibility between provider and customer.

Industry Common Concern Infrastructure Property
Defense Technical data accessible to foreign persons via shared cloud infrastructure Single-tenant hardware under U.S. jurisdiction. No offshore sub-processors. No foreign-national data access.
Healthcare Sensitive data routed through third-party processors without adequate safeguards Data never leaves the inference environment. No third-party data processors in the request path.
Finance Customer financial information processed on shared infrastructure Dedicated hardware. No shared GPU pools. No third-party sub-processors handling customer data.
Insurance Sensitive data exposure through multi-tenant processing environments Inference runs on isolated, single-tenant hardware. No data leaves the controlled environment.
Legal Privileged documents handled by third-party infrastructure Documents processed on hardware with no external data routing or third-party access.

API Compatibility

The API implements the OpenAI Chat Completions specification. Any application built against GPT-4o or GPT-3.5-turbo can switch to RO2 Labs by changing the base URL:

from openai import OpenAI

client = OpenAI(
    base_url="https://llm.ro2-labs.ai/v1",
    api_key="ro2_...",
)

response = client.chat.completions.create(
    model="llama3:70b",
    messages=[{"role": "user", "content": "Summarize ITAR 22 CFR 120."}],
)

Supported parameters include messages, temperature, top_p, max_tokens, and stream. Streaming responses use Server-Sent Events, matching the OpenAI SSE format.
