FAQs
What does Legion do?
Legion is a centralized AI platform for securely deploying Generative AI in any organization. Teams that use Legion become more efficient because Legion makes it easy for them to find information, create new content, and automate common workflows.
How does Legion Work?
Legion easily connects with your company’s existing systems and trusted data sources, making AI a seamless part of your workflow. It works with top language models like GPT, Claude, Llama, and Mistral, enhancing them with its powerful retrieval augmented generation (RAG) technology to provide accurate and relevant insights, and deliver answers you can trust, based on your own organizational data. Legion is flexible, and can be deployed in a way that fits your needs—whether in the cloud, on private servers, or at the edge. Plus, it comes with built-in tools for secure, large-scale AI deployment, including role-based access control, in-platform analytics, and a model hub for easy customization.
If I use Legion, will everyone have access to all my information?
No. Legion has built-in role-based access controls, so you can decide who within your organization has access to any given piece of information. Legion also will never train on your data.
How accurate is Legion compared to other Generative AI options?
Legion uses its proprietary Retrieval Augmented Generation (RAG) in conjunction with the latest models available to deliver best-in-class accuracy. Legion has performed significant testing, including the recognized “needle in a hackstack” (NIAH) benchmark and “multi-needle in a haystack,” in which it has outperformed even the most well known models. You can see the research for yourself here.
How is Legion different from ChatGPT?
ChatGPT connects to the internet. It’s great for brainstorming, quickly getting answers, and small tasks like rewriting something you wrote to sound better. Legion is similar to ChatGPT in that you can use AI to get answers and write new content, but it’s much more.
Not only can Legion connect with publicly available data on the internet, but it also connects to all of your organization’s internal data. With Legion, you can do anything from getting a summary of what happened at a meeting you missed, to finding the answer to a problem that someone who left the company solved years ago, or automating the first draft of a report you need to write. Plus, it’s secure enough that even the most skeptical security teams will give it the thumbs up.
I built a chat app using ChatGPT for my company. Why would I need Legion?
GPTs are great for personal projects, but they aren’t built to scale for large or complex use cases. Organizations require enterprise-grade features to successfully deploy Generative AI at scale. That’s where Legion comes in. Legion offers over 100 out of the box integrations with your company’s applications, including the ability to build custom integrations. It allows you to embed assistants into the systems your teams use every day, and it has the tools IT and Data Governance teams need to and security so airtight that even the US Department of Defense trusts it. It’s also efficient, which cuts down on potentially huge compute costs.
Which Large Language Models (LLMs) does Legion use?
Legion is a fully managed platform that integrates multiple open-source and proprietary large language models. It currently hosts models like Mistral 7B, Llama-3, Claude 3.7, and GPT-4.0, and can expand to hundreds more. Proprietary vendor API keys can be easily added.
Legion works with any model and makes it easy to switch models as new ones are released. This flexibility means you won't be locked into one vendor. Legion offers several models out-of-the-box and can connect to any proprietary model you have tokens for, including fine-tuned models.
Which industries use Legion?
Legion is suitable for any enterprise or federal agency. Today Legion proudly serves the following industries:
- Aerospace
- Manufacturing
- Supply Chain Management
- Government (both Defense and Civilian sectors)
How is Legion hosted?
Legion is deployable anywhere including On-Prem, Cloud, Hybrid, VPC, SaaS, Edge, and even Bare Metal environments—maintaining complete data sovereignty while meeting IL-2 through IL-6 compliance for government-grade security.
How does Legion help find information from different sources?
Legion seamlessly integrates with virtually all organizational data sources, using retrieval augmented generation (RAG) to unify information access—allowing users to find critical intelligence across systems without needing to knowing its specific location, a capability essential for federal knowledge management and decision support.
Is Legion a Chatbot?
No, Legion is not just a chatbot. It is a platform of AI-driven tools, including enterprise search, chat, content creation, and workflow automation that extend beyond simple conversational capabilities. With Legion, users can find answers, draft emails, generate reports, and generally improve operational efficiency across the board.
What are the capabilities of Legion?
Legion has many capabilities, a few are:
- Search: Retrieve information from diverse sources.
- Chat: Manage documents, policies, and manuals.
- Write: Draft emails, reports, and proposals.
- Summarize: Summarize meeting notes, emails, and research.

How does Legion keep data secure? Is Legion secure enough for my organization or agency?
Legion uses a multi-layered security approach. Data in transit is encrypted with TLS protocols, and data at rest is protected with AES-256 encryption in secure, access-controlled repositories. It maintains complete data sovereignty through a secure middle-man architecture between your data and LLMs. Your information never leaves its environment, is never used to train AI models, and remains under your control at all times.
Legion is secure enough for federal agencies, as evidenced by its deployment in US Department of Defense and Department of Energy environments. The platform is SOC2 compliant and supports secure deployment options including:
- On-premises
- Hybrid environments
- Private Cloud
- Air-gapped networks
- IL-2 through IL-6 (Classified SECRET) environments
What connectors and integrations does Legion offer?
Legion integrates directly with more than 100 systems of record and enterprise applications. As a general rule of thumb, if a system has an API, Legion can likely integrate with it. This is even true legacy systems and custom systems of record.
I don’t see my application listed as an integration with Legion? What data can you integrate with?
