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-agentsInstall · Models & pricing · Commands · Security · Platform · 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.
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 machineaether 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.

install.shorinstall.ps1, inspect it, then run it locally. SetAETHER_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.
One fleet, transparent per-token pricing — Claude, GPT, DeepSeek, Kimi, Gemma and Gemini for text & code, a 32-model image / video / 3D fleet, plus the Neo · Kronus · Aether-Vision orchestrators. aether models prints what your plan can actually reach, live from the server — the tables below are the current shape of it.
| Model | --model key |
Context window |
|---|---|---|
| Claude Opus 5 | opus5 |
1,000,000 |
| GPT-5.6 Sol | gpt56_sol |
1,050,000 |
| GPT-5.6 Terra | gpt56_terra |
1,050,000 |
| GPT-5.6 Luna | gpt56_luna |
1,050,000 |
| Kimi K3 | kimi_k3 |
1,048,576 |
| Gemini 3.6 Flash | gemini36_flash |
1,048,576 |
Six frontier models, every one with a million-token window. In the GPT-5.6 family, Sol takes the hardest reasoning and coding work, Terra is the balanced everyday pick, Luna is the fast, cost-sensitive one — and all three are priced through their true 1,050,000-token window, with the long-context band billed exactly rather than estimated. Opus 5 is an addition, not a replacement: --model opus still resolves to Claude Opus 4.8 and nothing you have configured changes.
| Plan | What you can select |
|---|---|
| Free | Claude Haiku 4.5 · DeepSeek V4 Flash · one image model as a teaser |
| Solo | + Claude Sonnet 5 · GPT-5.4 mini · the Neo 5.1T orchestrator · the full image fleet |
| Pro / Team | + Claude Opus 4.8 · GPT-5.5 · DeepSeek V4 Pro · Kimi K2.6 · Gemma 4 31B · the six frontier models above · video & 3D generation · the Kronus v2.4 and Aether-Vision orchestrators |
Media is 15 image models (Nano Banana Pro & 2, FLUX.2 Klein / Pro / Flex / Max, Recraft V3 & V4, Seedream 4.5, Riverflow V2, GPT-5 Image), 16 video models (Seedance 2.0 & 1.5 Pro, Veo 3.1 / Fast / Lite, Kling 3.0 Standard & Pro, Kling Video O1, Sora 2 Pro, Wan 2.6 & 2.7, Hailuo 2.3, HunyuanVideo 1.5, Grok Imagine), and Hunyuan3D 2.1 for text-to-3D — all drivable from the prompt line with /photogen, /videogen and /storyboard.
On --local, none of the above applies: you run any Ollama model you have pulled, with no account, no fleet, and no metering.
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
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 sessionFlags 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 by key (--model opus5, --model gpt56_terra, 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). |

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

Aether Agent is the terminal surface of Aether. Every surface below shares one login, one UVT balance, one model fleet, and one memory — start a task here, pick it up on the web, finish it in the IDE.
| Surface | Where | What it is |
|---|---|---|
| Aether AI on the web | app.aethersystems.net/chat | The Workbench — chat, agents you can launch, a work tray for everything they produce, image & video generation, your vault. |
| Aether Code | app.aethersystems.net/code | The browser IDE — the agent console docked beside your files, worktree teams and per-session transcripts, Nano compile & IR export. |
| Aether Design | app.aethersystems.net/design | Design Studio — canvas, creator and presets, with the agent editing the design directly. |
| AetherCloud desktop | github.com/DBarr3/aethercloud | The agentic desktop app — projects, workflows, the memory Vault, and local Actions runs that can open a pull request. |
| Aether Terminal | aethersystems.net/terminal | What this CLI looks like, before you install anything. |
