Overview
What Lux is
Lux is designed for workflows that cannot be completed through a clean API alone. It receives a natural-language goal, analyzes the current screen, chooses an interface action, observes the resulting screenshot, and repeats the cycle until the task finishes or reaches a limit.
OpenAGI provides three execution styles: Tasker for tightly specified, repeatable instructions; Actor for fast immediate tasks; and Thinker for vague or long-running goals. The official Python SDK can capture screenshots, execute mouse and keyboard actions, run from a command line, support multiple screens, and expose a real-time server for custom clients.
OpenAGI reports an 83.6 score on Online-Mind2Web and compares Lux favorably with competing computer-use models. Those figures are vendor-reported. Teams should independently test success rate, recovery, latency, cost, and safety on the exact sites and applications they intend to automate.
Use cases
Who Lux is best for
The strongest fit depends on the job you need the product to complete, not the size of its feature list.
Software quality assurance
Teams testing real user flows by navigating interfaces, entering data, and checking expected results.
Operations and data entry
Organizations moving structured information between dashboards, forms, and internal tools with human approval.
Computer-use research
Builders comparing agent modes, screen grounding, action selection, recovery, and long-horizon task performance.
Capabilities
Core Lux features
Vision-action loop
Lux repeatedly analyzes screenshots and emits interface actions, allowing it to operate software through the same visible controls a person uses.
Three execution modes
Tasker emphasizes controlled procedures, Actor emphasizes speed, and Thinker handles less-defined goals and longer runs.
Python SDK and CLI
The OAGI SDK supports automated task execution, manual step control, model and step limits, command-line runs, and execution-history exports.
Desktop action handlers
Official helpers can capture screens and operate mouse and keyboard inputs through PyAutoGUI, with separate Wayland support using ydotool and Flameshot.
Multi-screen targeting
Developers can enumerate displays and direct screenshots and actions to a chosen screen.
Custom client support
An optional FastAPI and Socket.IO server can relay screenshots and action events for browser extensions or other custom interfaces.
Process
How the Lux workflow works
Step 1
Select a bounded task
Start with a reversible, clearly measurable workflow and document the exact completion condition, allowed applications, and prohibited actions.
Step 2
Choose the execution mode
Use Tasker for known procedures, Actor for short responsive jobs, or Thinker for goals that require more planning and steps.
Step 3
Configure the environment
Install the SDK, create an API key, grant only necessary screen and accessibility permissions, and isolate the test account and machine where practical.
Step 4
Set action limits
Cap steps and runtime, restrict domains and apps, protect credentials, and require approval before purchases, messages, deletion, or external submission.
Step 5
Run and observe
Record screenshots, chosen actions, completion state, latency, errors, and human interventions so failures can be reproduced.
Step 6
Evaluate before scaling
Measure task success, false completion, recovery, cost, and side effects across interface changes and edge cases before production use.
Cost
Lux pricing and free plan
OpenAGI publishes the Lux Python SDK under the MIT license. A complete public API price table is not currently presented on the product or developer pages. OpenAGI's enterprise comparison shows Lux 1.0 at $0.10 in its benchmark cost graphic, but it does not define that figure as a universal billing unit. Check the developer dashboard for current API rates and request a custom quote for enterprise deployment.

Assessment
Lux strengths and limitations
Where it stands out
- Purpose-built for operating visual interfaces rather than only calling APIs
- Tasker, Actor, and Thinker modes cover different control and planning needs
- MIT-licensed Python SDK includes practical desktop, CLI, multi-screen, and server tooling
- Supports automation across otherwise disconnected applications
- Execution-history export and step controls help teams evaluate behavior
What to consider
- Public API pricing is not documented in a complete, generally applicable rate table
- Vendor-reported benchmark results may not predict reliability on a team's own software
- Computer-use errors can compound across long workflows and may produce false completion
- Screen captures and actions can expose credentials, personal data, customer records, and other sensitive information
- Interface changes, popups, permissions, latency, and anti-automation controls can break a previously successful flow
- The SDK is open source, but the Lux model is accessed as a hosted service rather than published open weights

Lux FAQs
What is Lux by OpenAGI?
Lux is a computer-use model that interprets screenshots and chooses mouse, keyboard, scrolling, and waiting actions to complete tasks in human-facing software.
What are Lux Tasker, Actor, and Thinker?
Tasker follows tightly defined procedures, Actor targets fast immediate actions, and Thinker handles vague or longer-running goals that require more planning.
Is Lux open source?
The official OAGI Python SDK is open source under the MIT license. The Lux model itself is accessed through OpenAGI's hosted API rather than distributed as open weights.
How much does Lux cost?
The SDK is free, but OpenAGI does not show a complete public API rate table on the product or developer pages. Check the developer dashboard for current usage pricing and contact OpenAGI for enterprise terms.
What can Lux automate?
Official examples include web data collection, software QA, financial data extraction, data entry, and multi-step workflows across websites and internal applications.
Can Lux control a desktop?
Yes. The official SDK includes screen capture and action handlers for desktop automation, including PyAutoGUI support and a documented path for Wayland environments.
Is Lux safe for unattended automation?
No computer-use agent should receive broad unattended authority by default. Use isolated accounts, least-privilege access, step and spend limits, audit logs, domain restrictions, and human approval for consequential actions.
Bottom line
Our Lux verdict
Lux is a capable developer-oriented option for automating visual software workflows, especially when APIs are unavailable. Its practical SDK and execution modes are attractive, but teams should treat benchmark and cost claims as starting points and demand strong real-task evaluation, transparent account pricing, and tight safety controls before production deployment.
