Enterprise, Hybrid LLM Solutions
In a rapidly evolving AI landscape, enterprises face a tough choice: Use public cloud-based LLMs for performance and scale — but sacrifice privacy
OR
Use private, on-prem LLMs for control and compliance — but sacrifice depth and speed
At LLM.co, we believe you shouldn’t have to choose.
Our Hybrid AI architecture gives you the security of private LLMs and the versatility of secure cloud models, all in one cohesive system.

Hybridize Your LLM with Leading Open & Closed-Source Large Language Models & AI Tools






No Longer Choose Between Privacy & Power
Enterprises today are caught in a tug-of-war between the security of private LLMs and the scale of public, cloud-based models. On one side, private deployments offer complete control over data, infrastructure, and compliance.
On the other, public models deliver state-of-the-art performance, broader context windows, and rapid iteration. At LLM.co, we believe you shouldn’t have to choose.
That’s why we architect Hybrid LLM solutions—systems that combine private and public AI in a way that is seamless, secure, and scalable.Hybrid AI enables enterprises to run private models on-premise or in a virtual private cloud (VPC), while selectively routing more complex or compute-intensive tasks to powerful public models like OpenAI, Anthropic, or Cohere.
This orchestrated approach allows organizations to maintain data sovereignty and compliance while still taking advantage of the latest advancements in language model performance.

Rule-Based Routing
(e.g., “never send contracts to the cloud”)

Confidence-based Fallback
(“if private LLM confidence < X, escalate to cloud”)

Custom Workflows
(e.g., prioritize local model but allow user override)

Hybrid AI's Solution to Privacy & Control
Built for compliance use-cases in mind:
Contract Review & Drafting-Private model handles internal templates and terms; cloud model compares against industry benchmarks.
Enterprise Search-Use a lightweight internal search agent, escalate to multi-document summarization in the cloud when needed.
Customer Support Agents-On-prem bots answer 80% of queries; public AI helps with long-form responses and sentiment adaptation.
Multi-Agent Workflows-Deploy teams of AI agents—some on-prem, some in the cloud—working in coordination on high-value business processes.
Features of Hybrid LLMs
Email/Call/Meeting Summarization
LLM.co enables secure, AI-powered summarization and semantic search across emails, calls, and meeting transcripts—delivering actionable insights without exposing sensitive communications to public AI tools. Deployed on-prem or in your VPC, our platform helps teams extract key takeaways, action items, and context across conversations, all with full traceability and compliance.
Security-first AI Agents
LLM.co delivers private, secure AI agents designed to operate entirely within your infrastructure—on-premise or in a VPC—without exposing sensitive data to public APIs. Each agent is domain-tuned, role-restricted, and fully auditable, enabling safe automation of high-trust tasks in finance, healthcare, law, government, and enterprise IT.
Internal Search
LLM.co delivers private, AI-powered internal search across your documents, emails, knowledge bases, and databases—fully deployed on-premise or in your virtual private cloud. With natural language queries, semantic search, and retrieval-augmented answers grounded in your own data, your team can instantly access critical knowledge without compromising security, compliance, or access control.
Multi-document Q&A
LLM.co enables private, AI-powered question answering across thousands of internal documents—delivering grounded, cited responses from your own data sources. Whether you're working with contracts, research, policies, or technical docs, our system gives you accurate, secure answers in seconds, with zero exposure to third-party AI services.
Custom Chatbots
LLM.co enables fully private, domain-specific AI chatbots trained on your internal documents, support data, and brand voice—deployed securely on-premise or in your VPC. Whether for internal teams or customer-facing portals, our chatbots deliver accurate, on-brand responses using retrieval-augmented generation, role-based access, and full control over tone, behavior, and data exposure.
Offline AI Agents
LLM.co’s Offline AI Agents bring the power of secure, domain-tuned language models to fully air-gapped environments—no internet, no cloud, and no data leakage. Designed for defense, healthcare, finance, and other highly regulated sectors, these agents run autonomously on local hardware, enabling intelligent document analysis and task automation entirely within your infrastructure.
Knowledge Base Assistants
LLM.co’s Knowledge Base Assistants turn your internal documentation—wikis, SOPs, PDFs, and more—into secure, AI-powered tools your team can query in real time. Deployed privately and trained on your own data, these assistants provide accurate, contextual answers with full source traceability, helping teams work faster without sacrificing compliance or control.
Contract Review
LLM.co delivers private, AI-powered contract review tools that help legal, procurement, and deal teams analyze, summarize, and compare contracts at scale—entirely within your infrastructure. With clause-level extraction, risk flagging, and retrieval-augmented summaries, our platform accelerates legal workflows without compromising data security, compliance, or precision.





Why Hybrid LLMs Make Sense for Enterprise AI Deployments
A hybrid approach unlocks significant advantages for enterprise teams. First and foremost, it maintains data privacy where it matters most. Client contracts, legal documents, proprietary code, and sensitive communications can be parsed and processed exclusively on private infrastructure. Meanwhile, non-sensitive queries, or those requiring higher-order reasoning, can benefit from the power of more advanced public models.
