new·The score now tells you which way it movedA brain's exam only ever grows: its own material writes questions, and so does every question a real caller asked and did not get answered. The score is a percentage over that growing set, so a brain that learned more could post a smaller number — and this week three did. One of them answered two MORE questions than the week before and showed eighteen points less. Printed as a single percentage, that reads as decline to a reader and as punishment to anyone who contributes material.all news →

10 notes, read out of this brain and free to use. Each one was extracted from a source and is re-checked against its exam.

Luma supported aspect ratios

Luma image models support the following aspect ratios: 1:1, 3:4, 4:3, 9:16, 16:9 (default), 9:21, and 21:9.

Luma model capabilities

Luma models provide ultra-high quality image generation, 10x higher cost efficiency compared to similar models, superior prompt understanding and adherence, unique character consistency capabilities from single reference images, and multi-image reference support for precise style matching.

Luma modify image mode

Luma supports modifying an image by passing image URLs in the prompt with referenceType 'modify_image'. Images must be passed as URLs and weight can be configured for each image in the providerOptions.luma.images array.

Luma image reference mode

Luma supports using up to 4 reference images to guide image generation with referenceType 'image'. The weight parameter (0-1) can be adjusted for each image to control the influence of reference images.

Luma style reference mode

Luma supports applying specific visual styles to generations using reference images with referenceType 'style'. The weight parameter controls the style influence.

Luma character reference mode

Luma supports creating consistent and personalized characters using up to 4 reference images of the same subject with referenceType 'character'. Each image reference includes an id field (e.g., 'identity0'). More reference images improve character representation.

Luma modify image example

Example of modifying an image with Luma: `await generateImage({ model: luma.image('photon-flash-1'), prompt: { text: 'transform the bike to a boat', images: ['https://hebbkx1anhila5yf.public.blob.vercel-storage.com/future-me-8hcBWcZOkbE53q3gshhEm16S87qDpF.jpeg'] }, providerOptions: { luma: { referenceType: 'modify_image', images: [{ weight: 1.0 }] } } });`

Luma image reference example

Example of using image reference with Luma: `await generateImage({ model: luma.image('photon-flash-1'), prompt: { text: 'A salamander at dusk in a forest pond, in the style of ukiyo-e', images: ['https://hebbkx1anhila5yf.public.blob.vercel-storage.com/future-me-8hcBWcZOkbE53q3gshhEm16S87qDpF.jpeg'] }, aspectRatio: '1:1', providerOptions: { luma: { referenceType: 'image', images: [{ weight: 0.8 }] } } });`

Luma style reference example

Example of using style reference with Luma: `await generateImage({ model: luma.image('photon-flash-1'), prompt: { text: 'A blue cream Persian cat launching its website on Vercel', images: ['https://hebbkx1anhila5yf.public.blob.vercel-storage.com/future-me-8hcBWcZOkbE53q3gshhEm16S87qDpF.jpeg'] }, aspectRatio: '1:1', providerOptions: { luma: { referenceType: 'style', images: [{ weight: 0.8 }] } } });`

Luma character reference example

Example of using character reference with Luma: `await generateImage({ model: luma.image('photon-flash-1'), prompt: { text: 'A woman with a cat riding a broomstick in a forest', images: ['https://hebbkx1anhila5yf.public.blob.vercel-storage.com/future-me-8hcBWcZOkbE53q3gshhEm16S87qDpF.jpeg'] }, aspectRatio: '1:1', providerOptions: { luma: { referenceType: 'character', images: [{ id: 'identity0' }] } } });`
