# Images and speech Two commands that produce a file rather than a paragraph. Both are charged per generation rather than by length, and a failed generation costs nothing. ## Generating images `?image a lighthouse at dusk, long exposure` returns a picture. It arrives in the conversation like any other message, encrypted the same way, and you can save it from there. On the standard tier this uses the built-in generator. With a [Pro model](https://nymbot.ai/docs/models/#pro) selected you get the frontier generators instead. ## Choosing a generator `?image models` lists what is available with prices, and costs nothing. With a Pro model selected, `?image --model ` picks one: Nano Banana Pro, Nano Banana 2, Imagen 4, FLUX 2 Max, FLUX 2 Pro, Seedream 5 Pro, GPT Image 2, Grok Imagine and Recraft v4 Pro. They differ in what they are good at rather than in quality — text rendered inside the image, photographic realism, illustration, and how literally each takes a long prompt. If one misreads a description, another usually will not. ## Speech `?speak ` returns a spoken clip of up to 800 characters. Longer text is refused rather than truncated, so you never pay for half a sentence. ## What they cost | Command | Standard | With a Pro model selected | | --- | --- | --- | | `?image` | 5 standard credits | 2–3 Pro credits, depending on the generator | | `?speak` | 3 standard credits | 1 Pro credit | | `?image models` | Free | | Because these are flat per-generation charges, the length of your description does not change the price. See [credits and pricing](https://nymbot.ai/docs/credits/) for how the two balances work.
