OEL 1.0.0

Language and toolchain

A typed, compiled language for agents, with one command-line tool to create, check, format, build, run and debug projects.

Tooling

Functions in other languages

Your application can hold private functions written in other languages, with typed OEL signatures, built and run with your own toolchains, pinned by version.

Language

Agents and workflows

Prompts as business policy, tools, typed inputs and outputs, multi-agent patterns and subagents, shared budgets, retries, human approvals and runs that resume from a storage point you declare.

More about agents

Two-way typed edges

Every edge is a typed, two-way channel: OEL generates the communication between nodes, agents and subagents from your edge declarations, with no client or server code for you to write.

Subagents and two-way edges

Models and knowledge

OpenAI-compatible model clients for local and cloud models, MCP tools, agent-to-agent delegation over A2A, multimodal input and retrieval over your own knowledge (RAG).

Model and knowledge features

Skills

A skill is a versioned, reusable bundle of instructions, typed tools and functions that an agent or subagent loads through the skills it declares; its tools run only where the agent's permissions allow, and it adds nothing the agent did not declare.

Models, tools and testing

Connect to your services

You turn an agent into an HTTP or gRPC service, react to events and schedules, and call your existing programs as tools.

Services and connections

Packages

The official registry at pack.openeng.ai, with signed versions published only by OpenEng, and private packages you build and host yourself.

About packages

Platforms

Linux, macOS, Windows, containers and microcontroller boards. Programs run on servers, containers and devices, with nothing to compile or download at startup.

Platforms and deployment

Your platform's build

The OEL 1.0.0 build for Linux, macOS or Windows comes with target management and a health check, and desktop and server programs written in OEL alone need nothing else installed.

Do I need to install anything else?

Distributions

OEL 1.0.0 is the full distribution; smaller distributions of the same version leave out components, such as support for other languages or for agents, and refuse a feature they leave out by naming it.

Platforms and deployment

Operations

Time and token usage reports, structured logs, per-agent limits, staged deployments and rollback.

Platforms and deployment

Optional packages

Robotics, scientific computing and quantum computing, including ROS 2 support and quantum circuits that export to OpenQASM and QIR.
