Aether Agent

A coding agent for your terminal — runs on hosted frontier models or fully offline on your own machine.

Aether Agent is in beta. Updates are shipping quickly.

npm i -g aether-agents --ignore-scripts     # or run once: npx --ignore-scripts aether-agents

Install · Models & pricing · Commands · Security · Release notes

It scans, plans, edits, and runs your tests — in your repo, on your terms. Verification is ground truth: the agent re-runs your test command and reads the exit code itself, so "done" is never the model's word. And with QOPC memory it learns from what you accept, revise, or discard — measurably better the more you use it, no config, no fine-tuning.

Install in three moves

npm i -g aether-agents --ignore-scripts     # 01 — drop it in (Node ≥ 24)

aether auth login          # 02 — sign in once
aether agent               #      …terminal opens. Just start chatting.

ollama pull qwen2.5-coder:7b   # 03 — or go offline: no account, no network
aether agent --local           #      …same terminal, nothing leaves the machine

aether agent opens the REPL — chat with the model, slash-commands at hand, the agent edits files and runs your tests in the same session. Both brains run through the same host loop, render, tools, and commands — switching just swaps the transport. On the hosted path your code stays local and only the prompt + context you send leaves; on --local, nothing leaves at all. The local brain runs on Unlimited Context — Aether's open-source (Apache-2.0) memory engine that gives any Ollama model a billion-token working memory.

Prefer the installer UI? Download install.sh or install.ps1, inspect it, then run it locally. Set AETHER_VERSION=0.1.0 (shell) or -Version 0.1.0 (PowerShell) to pin an exact release. The canonical npm command above verifies registry integrity and disables lifecycle scripts; there are no native or runtime dependencies and no daemon.

Models & pricing

One fleet, transparent per-token pricing — Claude, GPT, DeepSeek, Kimi, and Gemma for text & code, image and video generation, plus the Neo · Kronus · Aether-Vision orchestrators. On --local, any Ollama model you've pulled. Run aether models to list everything from the terminal.

Usage is metered in UVT — one universal credit, one balance, shared across this agent, the AetherCloud desktop, and Aether AI on the web. Free tier to try (no card), subscription for premium models, UVT top-ups for pay-as-you-go. Current tiers and prices: aethersystems.net

Commands

Inside the REPL, / commands control the whole session — type /help to see them in-session, or click the card above for the full reference. That includes generating images and video from the prompt line (/photogen, /videogen, /storyboard …) and connecting MCP servers with /mcp. From the shell:

aether agent                      # the main thing — open the REPL and chat
aether agent --local              # same REPL on a local Ollama brain (offline)
aether models                     # list models + orchestrators
aether resume                     # replay / continue the last session

Flags you can set when launching the REPL (or pass with an inline task aether agent "<task>" for one-shot autonomous mode):

Flag	What it does
--local	Local Ollama brain instead of the hosted API.
--model <id>	Force a model (--model opus, or an Ollama tag with --local).
--effort <tier>	Budget ceiling: LOW · MED · MAX · ULTRA · CODEPRO.
--test-cmd <cmd>	Command the verification gate runs (default pytest -q).
--worktree	Fresh git worktree on an auto-named branch (isolated).
--repo <owner/name>	Clone a GitHub repo via your own gh/git auth, work it in a worktree.
-y, --yes	Auto-confirm prompts (non-interactive).

Development

The application and executable test suite are fully on TypeScript 7.0.2, with Node.js 24 or newer as the supported runtime. Strict ESM compilation emits the distributable JavaScript to dist/; the published package contains dist/src and excludes compiled tests.

Run the release gates from a clean checkout:

npm ci
npm run typecheck
npm test
npm run smoke
npm pack --dry-run

The verified TypeScript 7 release baseline is tagged v0.1.0. Migration details and measurements are in the TypeScript 7 upgrade design.

Security

• Your code stays local. Edits apply on your machine, path-guarded — the client refuses to write outside your working directory.
• Verification is ground truth. The host runs your test command and reads the exit code itself; "done" is never the model's word.
• Tokens are credentials. Stored chmod 600, never committed; aether auth logout clears them.
• The server is the authority. On the API path, usage limits, model access, and signed chain-of-custody receipts are enforced server-side — the client only displays what the server reports.

Part of the Aether platform

Aether Agent is the terminal sibling of AetherCloud, the agentic desktop app — same login, same UVT balance, same model fleet. Drive your repo from the command line; drive projects, workflows, and the memory Vault from the desktop. Get the desktop at aethersystems.net/download — installs in about a minute, no card needed.
