Image Generation

RunAnywhere.images generates an image from a prompt.

const result = await RunAnywhere.images.generate('A lighthouse at dusk, oil painting', {
  negativePrompt: 'blurry, text, watermark',
  width: 512,
  height: 512,
  steps: 20,
  seed: 42,
})

Options

Field	Default	Meaning
`negativePrompt`	none	What to avoid
`width`	model default	Output width
`height`	model default	Output height
`steps`	model default	Denoising steps; more is slower and usually better
`guidanceScale`	model default	How closely to follow the prompt
`seed`	random	Fix it to reproduce an image
`mode`	generate	Generate or inpaint
`reportPartials`	`false`	Emit intermediate images while streaming

Watching it appear

With reportPartials on, the stream emits intermediate images, so you can show the picture resolving rather than a spinner.

for await (const event of RunAnywhere.images.generateStream('A lighthouse at dusk', {
  steps: 20,
  reportPartials: true,
})) {
  if (event.type === 'partial') showPreview(event.image)
  if (event.type === 'completed') showFinal(event.result)
}

Reproducing an image

Fix the seed and every other option, and the same prompt produces the same image. Without a fixed seed, it will not.

Cost

Image generation is the heaviest thing in the SDK. A 512×512 image at 20 steps takes far longer than a text completion and warms the device noticeably. Run one at a time, show progress, allow cancellation, and do not put it on a timer.

Availability

Check before offering it:

const capabilities = await RunAnywhere.capabilities()

A diffusion model has to be registered and a backend has to serve it. The namespace existing does not mean the catalog has an entry.
