Introducing Lumi0

Today, we're excited to introduce Lumi0—AI infrastructure for modern AI applications.

As AI applications become more capable, developers spend less time building AI and more time building the infrastructure around it: memory, context management, retrieval, and workflows.

Lumi0 provides these building blocks out of the box, starting with branch-based memory and expanding toward a complete AI runtime for production applications.

Why We Built Lumi0#

Large language models are powerful, but they're inherently stateless.

Every request requires developers to reconstruct context, manage conversation history, and decide what information should be sent back to the model.

As products scale, this becomes increasingly difficult.

Developers end up rebuilding the same infrastructure repeatedly.

These are infrastructure problems, not application problems.

Our goal is simple:

Developers should focus on building AI products—not rebuilding AI infrastructure.

Introducing Lumi0#

Lumi0 is building the infrastructure layer for AI applications.

Instead of combining multiple services for memory, retrieval, and orchestration, developers can integrate a single platform designed specifically for AI workloads.

Current capabilities include:

Branch-Based Memory#

Traditional AI memory stores information in a single timeline.

Real applications don't work that way.

Users switch projects.

Agents explore different solutions.

Applications need isolated contexts without losing shared knowledge.

Lumi0 introduces branch-based memory, allowing applications to maintain multiple independent contexts while sharing relevant information when needed.

This makes it easy to build AI systems that can:

• Manage multiple projects
• Experiment safely
• Separate user contexts
• Preserve historical state
• Merge knowledge across branches

Getting Started#

Install the SDK.

npm install @lumi0/sdk

# pnpm
pnpm add @lumi0/sdk

# bun
bun add @lumi0/sdk

Initialize the client.

import { Lumi0 } from "@lumi0/sdk";

const client = new Lumi0({
  apiKey: process.env.LUMI0_API_KEY!,
});

Store a memory.

await client.memory.create({
  userId: "user_123",
  branch: "main",
  content: "The user prefers TypeScript and Bun.",
});

Retrieve memories.

const memories = await client.memory.search({
  userId: "user_123",
  query: "What programming language does the user prefer?",
  limit: 5,
});

console.log(memories);

Built for Production#

Lumi0 is designed for production AI applications from day one.

Whether you're building AI agents, coding assistants, customer support platforms, or autonomous workflows, Lumi0 provides the infrastructure needed to manage memory and context reliably.

Roadmap#

Memory is only the beginning.

We're building a complete infrastructure platform for AI applications.

Upcoming capabilities include:

Open Source & Developer First#

Lumi0 is built with developers in mind.

We believe AI infrastructure should be simple to integrate, easy to scale, and flexible enough for any application.

Our APIs are designed to feel familiar, our SDKs minimize boilerplate, and our documentation focuses on getting developers into production quickly.

Start Building#

Ready to build AI applications that remember?

We're just getting started.

The future of AI applications won't just depend on better models—it will depend on better infrastructure.
