# Presets

A preset bundles the model settings and prompts that shape how a chat writes: how creative it is, how it's prompted, and how it behaves. Save a preset once and apply it to any chat.

## Create a preset

1. Go to **Create → Create Preset** (or `/presets/new`).
2. Set the sampling parameters and prompts.
3. Save. Presets default to **private** until you publish them.

## Every field explained

### Sampling

These control the model's randomness and word choice:

- **Temperature** — how creative/unpredictable output is. Higher = wilder.
- **Top P** — nucleus sampling; consider only the most-likely tokens summing to P.
- **Top K** — consider only the K most-likely tokens.
- **Top A** — an alternative cutoff based on the top token's probability.
- **Min P** — drop tokens whose probability is below a fraction of the top token's.
- **Repetition penalty** — discourage the model from repeating itself.
- **Frequency penalty** — penalize tokens by how often they appear.
- **Presence penalty** — penalize tokens that have appeared at all.
- **Max output tokens** — cap on reply length.

### Prompts

- **System prompt** — the master instruction for the model.
- **Main prompt** — additional conversation-level instructions.
- **Jailbreak prompt** — extra directives that loosen default constraints.
- **Assistant prefill** — text the model starts its reply with.
- **Impersonation prompt** — instructions for playing the character's voice.

### Sharing

- **Set as default** — apply this preset to new chats automatically.
- **Visibility** — `public`, `unlisted`, or `private`.
- **Description** — a note about when to use this preset.

## Using presets in chat

In a chat, pick a preset from the settings panel (or rely on your default). Different characters or moods can each have their own preset — a "literary" preset for long-form scenes, a "snappy" one for quick banter.

> **Tip**

> Temperature is the fastest lever. If replies feel flat, raise it; if they spiral, lower it and raise repetition penalty a notch.
