# Pistachio Pass - Full Documentation
> NFT capacity passes for the Pistachio AI inference client. ERC-721 on Base mainnet by DRM3 Labs.

## Overview
Pistachio Pass is a collection of ERC-721 NFTs on Base mainnet (Ethereum L2) that control AI inference capacity for the Pistachio client. Pistachio connects to the Morpheus decentralized compute network, enabling permissionless access to AI models. NFT passes determine how much MOR capacity a wallet can stake, which directly affects session length and gas efficiency.

## Free Tier
Claim your free Starter pass for 20 MOR of inference capacity (~$0.01 gas on Base). This is enough for approximately 23-minute AI sessions before a restake transaction is needed. No signup, no API keys. Just connect your wallet, claim the Starter pass, and start using AI.

## NFT Tiers

### Bronze Pass
- Capacity: +200 MOR (220 total with free tier)
- Cost: 5 MOR
- Session length: ~3.8 hours between restakes
- Best for: Casual users who want longer uninterrupted sessions

### Silver Pass
- Capacity: +1,000 MOR (1,020 total with free tier)
- Cost: 20 MOR
- Session length: ~1.6 days between restakes
- Best for: Regular users and developers

### Gold Pass
- Capacity: +5,000 MOR (5,020 total with free tier)
- Cost: 80 MOR
- Session length: ~8 days between restakes
- Best for: Power users and small teams

### Diamond Pass
- Capacity: +20,000 MOR (20,020 total with free tier)
- Cost: 250 MOR
- Session length: ~33 days between restakes
- Best for: Organizations and heavy production workloads

## How Capacity Works
Capacity is additive. If a wallet holds multiple NFTs, their capacities stack on top of the 20 MOR free tier. Larger capacity means:
- Longer AI inference sessions without interruption
- Fewer on-chain restake transactions
- Less ETH spent on gas fees over time
- More cost-effective AI usage at scale

The relationship between capacity and session length is approximately linear: 1 MOR of capacity provides roughly 1.15 minutes of continuous inference time.

## What Is Pistachio?
Pistachio is a local-first AI inference client built in Rust by DRM3 Labs. It connects to the Morpheus decentralized compute network, routes requests to available AI providers, and manages wallet-based authentication and MOR staking automatically. Pistachio runs on your machine. No cloud accounts, no API keys, no middlemen.

Install via Homebrew:
```
brew tap drm3labs/drm3
brew install pistachio
pistachio serve
```

## What Is Morpheus?
Morpheus is a decentralized AI compute network where providers stake MOR tokens to offer inference services, and consumers stake MOR to access those services. Pistachio is a consumer client for the Morpheus network.

## What Is DRM3 Labs?
DRM3 Labs is the company building Pistachio and the surrounding infrastructure. DRM3 is focused on decentralized data rights management and AI inference tooling.
