# AitherOS ADK (Agent Development Kit)

> Build AI agent fleets with any LLM backend. Local-first with vLLM/Ollama, cloud via Elysium. One `pip install`, one line to connect.

## Install

```
pip install aither-adk
```

## Quick Start — Local Agent

```python
import asyncio
from adk import AitherAgent

async def main():
    agent = AitherAgent("my-agent")  # Auto-detects vLLM/Ollama
    response = await agent.chat("Hello!")
    print(response.content)

asyncio.run(main())
```

## Quick Start — Cloud Inference via Elysium

```python
import asyncio
from adk import AitherAgent
from adk.elysium import Elysium

async def main():
    ely = await Elysium.connect(api_key="aither_sk_live_...")
    agent = AitherAgent("my-agent", llm=ely.router)
    response = await agent.chat("Hello from cloud!")
    print(response.content)

asyncio.run(main())
```

## Serve as API

```bash
aither-serve --identity aither --port 8080
```

Exposes OpenAI-compatible endpoints:
- `POST /v1/chat/completions`
- `GET /v1/models`
- `GET /health`

## Features

## Elysium Cloud Inference

Register at https://demo.aitherium.com or via API:

```python
ely = Elysium()
await ely.register(email="you@example.com", password="...")
await ely.login(email="you@example.com", password="...")
```

Models available by tier:
- **Free**: aither-small (llama3.2:3b)
- **Pro** ($9/mo): + aither-orchestrator (nemotron-8b)
- **Enterprise**: + aither-reasoning, aither-vision, aither-coding

## Agent Registration

Register your custom agent with the Aitherium network:

```python
ely = await Elysium.connect(api_key="aither_sk_live_...")
await ely.register_agent("my-agent", capabilities=["code", "search"])
agents = await ely.discover_agents(capability="code")
```
