The assistant model at the centre of the lab’s work. Its face ships today; its mind is not in any build yet.
In development
Sub-bit models
Large models in consumer GPU memory. Quality is not yet measured, so no claim is made.
In development
More open source
The app shell, Lattice, Sinai’s face and the simulator, as public mirrors, piece by piece.
The simulator today, on the app’s Compute page. It is planned to grow into the world Sinai learns in.Real app screen · demo content · development build, 9 Oct 2026
Builds
Official or open source.
Official build Installer
With Alelyon’s closed plug-ins: receipt replay on the lab’s engine, voice, and later Sinai’s own mind.
Open build Source
Only what is public. It checks a receipt’s signature, data and records, and never marks one verified without the replay engine.
Requirements
System requirements
Windows
Windows 11, 64-bitWindows 10 is not tested yet.
Graphics
AnyWithout a GPU the sign-in scene is a still picture; the rest is the same.
Local models
OptionalA GPU with enough memory for the model, or a patient CPU.
Agent browser
Edge or ChromeOnly if you turn it on. Edge ships with Windows.
Internet
Only what you chooseSign-in, friends, hosted models and research searches.
Account
Optional“Use offline” skips it.
Good to know
The fine print
Lattice
Commands, tools and file writes ask first unless you allowed them. A model off your computer sees what you send it.
Models
A hosted model runs under its provider’s terms and prices; Alelyon does not resell or proxy it.
Research
OpenAlex needs a free key for real use. The archive stays on your computer.
Sinai
Sinai’s own model is in development and not in any build; until then it uses the model you pick and says which.
Friends
Friends needs an Alelyon account and the live service. Messages are stored on Alelyon’s server in plain text: they are not end-to-end encrypted.
Provider names
Names are the providers’ own; Alelyon is not affiliated with them.
An AI lab, and the Windows app it builds for working with AI: Lattice (an AI code editor with an agent), local and cloud models, a research assistant, the assistant Sinai, and friends.
Is Alelyon free?
Nothing on this site asks for payment: the app and an Alelyon account cost nothing today, and no price has been set for later releases. This page will say so before one applies.
Models you bring can cost money through their providers, or through your Claude or ChatGPT plan when you use Claude Code or Codex.
Does it work offline? Do I need an account?
No account is needed. Choose “Use offline” at sign-in and everything on your computer works: your models, files, the IDE and saved research. An account adds friends and Alelyon’s hosted preview; sign in with GitHub, Google, Hugging Face or LinkedIn.
Is my code private? What leaves my computer?
Only what you send to a service you chose: a prompt to a hosted model, a search to OpenAlex or arXiv, a message to a friend, a sign-in to Alelyon. On its own, the app only asks Alelyon’s sign-in service whether it is up, with no account details. There is no analytics or telemetry, and with a local model through llama.cpp your prompts never leave your computer.
