Compact visual reasoning model for fast image QA and scene captions
moondream/moondream3-previewmixpeek://image_extractor@v1/moondream3_preview_v1Overview
Moondream3 Preview is a compact image-text model from Moondream focused on visual question answering, captioning, and deployable visual reasoning. It continues the Moondream line's emphasis on small-model ergonomics while keeping enough visual reasoning quality for production perception pipelines.
On Mixpeek, Moondream3 is a useful second-stage model after cheap embedding retrieval. Use it to caption candidate images, answer bounded visual questions, or extract concise observations that an agent can cite.
Architecture
Image-text-to-text model exposed through Hugging Face Transformers custom code. It supports caption generation, visual question answering, and streaming output for interactive applications.
Mixpeek SDK Integration
import { Mixpeek } from "mixpeek";
const mx = new Mixpeek({ apiKey: "API_KEY" });
// Managed: create a collection over a bucket; Mixpeek runs this model's extractor
const collection = await mx.collections.create({
namespace_id: "my-namespace",
collection_name: "my-collection",
source: { type: "bucket", bucket_ids: ["bkt_your_bucket"] },
feature_extractor: {
feature_extractor_name: "scene_caption",
version: "v1",
parameters: { model_id: "moondream/moondream3-preview" },
},
});Capabilities
- Image captioning with short and detailed modes
- Visual question answering over retrieved images
- Compact deployment compared with large VLMs
- Streaming generation support
