Open-source AI infrastructure

An open foundation for evolving AI systems.

AISpec is an open specification and open-source tooling for describing, versioning and understanding how AI systems evolve.

We are building the foundation in the open, starting with the specification, AISpec Core and the CLI.

Why AISpec

AI systems evolve. Your history should too.

AI systems constantly change. Prompts change. Models change. Providers change. Configurations change. Results change.

AISpec keeps those changes connected so teams can understand what happened, reproduce successful states, compare experiments and return to versions that worked.

Version

Track meaningful changes across AI systems.

Experiment

Test different prompts, models and providers safely.

Compare

Understand quality, performance and cost across versions.

Rollback

Return to a known-good state when an experiment goes wrong.

Open Source

The foundation is open.

AISpec is being built in the open. The specification, core tooling and CLI form the foundation that anyone can inspect, use, extend and contribute to.

OPEN STANDARD

Specification

The open specification that defines how AI systems, components, versions and changes can be described.

OPEN SOURCE

AISpec Core

The core implementation for working with AISpec projects, versions, states and history.

DEVELOPER TOOL

AISpec CLI

A command-line interface for creating, inspecting, versioning and evolving AISpec projects locally.

Built for developers

Use AISpec wherever you build.

Install, run and integrate the open tooling into your own workflow.

Human-First

AI is a tool. Humans remain the authors of the work.

AISpec keeps attribution, provenance and traceability visible across the workflow. It shows what AI generated and who shaped the result before it became final.

Relationship

Human
AI Tool
Result

AISpec doesn't just tell you what AI generated. It tells you who shaped the work.

Human contribution

Who contributed, their role and what they directed, edited, reviewed or approved.

AI contribution

Which model, prompt and step generated or transformed the output.

Provenance

Where the asset came from, how it changed and which version led to the result.

Approvals

Who reviewed or approved the result and when the decision was made.

Creative Director

Human contributor

Directed the generation and selected the final result.

Image Model

AI contribution

Generated the initial visual variations.

Editor

Human contributor

Retouched and approved the final version.

Human direction remains visible even when AI contributes to the outcome.

How AISpec works

A system has structure. Its changes have history.

AISpec connects the components of an AI system with the states, changes and experiments that shape how it evolves over time.

  1. 01

    System

    A structured description of the AI system and the components that belong to it.

    project
  2. 02

    Component

    An agent, prompt, tool, memory or other part of the system that can evolve independently.

    versionable
  3. 03

    State

    A recorded state of a component at a specific point in time.

    snapshot
  4. 04

    Change

    A documented transition that connects one state to the next.

    history
  5. 05

    Experiment

    An isolated path for exploring changes without losing the connection to the original system.

    branch
  6. 06

    Resolve

    Keep a successful change or return to a previous recorded state when needed.

    merge / restore
Future layer

AISpec Cloud

Collaboration built on the open foundation.

AISpec Cloud is a future hosted layer for teams that want to collaborate, share project history and work with AISpec without managing the infrastructure themselves.

The open-source core remains the foundation.

    AISpec Language

    A vision for how AI systems will be described.

    Vision

AISpec Language

A language designed specifically for building and evolving AI systems. This is a long-term direction we're exploring — not an available feature today.

Be there when AISpec goes live.

We're building the infrastructure we wish existed for AI development. Join the waitlist and follow the evolution.
