# Prompt and settings > Write and size the prompt, reuse prompts from Prompt History, and set aspect, duration, audio, Auto-Upscale and frame interpolation. Source: https://flashboards.yaroflasher.com/docs/generation/prompt-and-settings Last verified: 2026-10-13 (checked against FlashBoards app build 042ae39db) The prompt box and its controls sit at the bottom right of the board. You only see the settings the active model has. ## The prompt box Click **Enter prompt...** and type. `Enter` adds a new line. To run, click **Generate** (the sparkle button with the price) or press `⌘ + Enter`. * Drag the top-left corner to resize the box; double-click it to reset. * **Clear prompt** empties the box. * A character counter appears near the model's limit. If a prompt is too long or too short, **Generate** tells you and doesn't start. Some workflows lock the prompt (**Prompt locked for this workflow**) or don't need one (**No prompt required**). Fill the labelled slots and generate. There is no negative prompt field. ![Reference input on the left, the prompt box with aspect, upscale and Generate controls on the right](https://media.yaroflasher.com/docs/media/generate-panel.w2880.256e5521.webp) ## Prompt History Click the clock button (**Prompt History & Library**) under the prompt box, or press `Control + H` (Windows: `Ctrl + H`). The window has a search box and three tabs: * **Library**: ready-made templates by category. * **Recent**: prompts you've generated with, and the model used. * **Saved**: prompts you saved. Click **Use this prompt** to put it in the prompt box, or **Copy to clipboard**. On **Recent**, **Save to library** keeps a prompt. On **Saved**, you can also **Edit prompt**, **Add to favorites** and **Delete prompt**. ![The Prompt History window on the Library tab with prompt templates](https://media.yaroflasher.com/docs/media/prompt-history-library.w1792.60745e8f.webp) ## Model options The row under the prompt shows the active model's options, such as **Aspect**, **Resolution**, **Duration**, **Mode**, **Seed**, **Style**, **Voice** or **Steps**. Open a control and choose a value. * Values are remembered per model. * The price on **Generate** updates as you change options. * Some image models have an **Images** control (1 to 4). Each image is charged. To run one setup over several items, see Shift batching in [Generate](https://flashboards.yaroflasher.com/docs/generation/generate.md#batch-one-setup-over-many-images). * Some image models also have **Quality**, **Background** and **Format**. Higher quality costs more. **Transparent** background needs PNG or WebP, so **JPEG** is hidden while it's on. * Some audio models show simple fields under the prompt instead, such as duration, voice, language or lyrics. ### Less common options A few models have options of their own: * **Creativity**, for example on **Topaz Starlight**: how much generative detail the model adds, **Low**, **Middle** or **High**. * **Prompt Expansion**, for example on **MiniMax H3 Max Turbo**: **Disabled** uses your prompt unchanged. **Balanced** and **Quality** let the model expand your prompt automatically. * **Prompt Influence**, on **ElevenLabs Sound Effects v2**: a slider from 0 to 1 for how closely the sound follows your description. * **Loop**, on **ElevenLabs Sound Effects v2**: makes the sound loop seamlessly. ### Audio on video models Video models that can make sound show an **Audio** toggle with a speaker icon (hover it for "Audio: on" or "Audio: off"). It can change the price. ### Auto-Upscale For image models only. Click **Toggle Auto-Upscale** (the chevrons), then **Select Upscale Model** to pick the upscaler and **2x** or **4x**. The menu shows each upscaler's price. When the image finishes, it's upscaled and gets a green badge with the scale. The upscale is a separate paid run, but its estimate is included in the price on **Generate** while Auto-Upscale is on. Hover the price to see the base run, upscale steps and total. If the upscale fails, you keep the original image. Auto-Upscale turns off when you change model. ![Auto-Upscale turned on with Select Upscale Model open, showing 2x and 4x and each upscaler's price, and the Generate button showing the total](https://media.yaroflasher.com/docs/media/prompt-auto-upscale.w960.f45a6eef.webp) ![The Generate tooltip with Auto-Upscale on, listing the image price, the upscale price and the Total](https://media.yaroflasher.com/docs/media/prompt-upscale-total.w1110.395303a6.webp) ### Frame interpolation On models that support it, click **Enable Frame Interpolation** and pick a rate such as 2x or 4x. It adds frames for smoother motion but doesn't raise resolution. The same control is in the **Form** tab in [Model Details](https://flashboards.yaroflasher.com/docs/generation/model-details.md). ## Related - [Inputs and references](https://flashboards.yaroflasher.com/docs/generation/inputs.md) - [Models and workflows](https://flashboards.yaroflasher.com/docs/generation/models-and-workflows.md) - [Keyboard shortcuts](https://flashboards.yaroflasher.com/docs/reference/keyboard-shortcuts.md)
