# vision.embedding@1
|
||
|
||
`vision.embedding@1` accepts a bounded batch of image or text items. Each item has exactly one modality. Images are PNG/JPEG, base64 encoded at the gateway boundary and constrained to 4096×4096 pixels in the runtime.
|
||
|
||
The response exposes normalized vectors, their dimension, and an immutable `EmbeddingSpace` identifier. Equal dimensions never imply compatible spaces. Identity binds the exact artifact revision and digest, RuntimeProfile fingerprint, processor, input image size, normalization and pooling/projection semantics.
|
||
|
||
The preferred SigLIP2 SO400M candidate is retained as discovery evidence but is not forced into a shared 16 GiB GPU envelope. The M9 safe baseline is SigLIP2 Base patch16/224, loaded offline by `transformers_siglip2`.
|
||
|
||
Evaluation uses a deterministic, locally generated image/text retrieval set and typed Recall@K, MRR, latency and peak-VRAM evidence. Fixtures never leave the local environment.
