Meshy 7.1 Ultra 4K: when a 3D model is overkill

Meshy 7.1 arrived Sep 10, 2026 with Ultra 4K, geometry resolution of 2048^3 to 4096^3 and raw meshes of up to 80 million triangles, from a single image. Sume has no image-to-3D model and does not output GLB files; if the goal is showing a product from all sides, a short turntable-style video is the Sume answer.

What Meshy 7.1 added

The dates and specs below come from a Neural4D comparison page, a third party, so check Meshy's own notes for current details.

Do you need a mesh?

A mesh is the right output when someone will rotate, light, rig or print the object. For an ad, a product page or social post, viewers watch a clip, and a mesh of tens of millions of triangles is far more than that needs.

Sume's catalog is images, video, audio and avatar tools. Its image catalog has no 3D model, and the video docs do not list a mesh output, so there is nothing to export as GLB.

A spin video from one still

Sume's /v1/videos accepts frame_images with frame_type: first_frame for image-to-video. Give it a clean product photo on a plain background and describe the motion in the prompt. Check supported_frame_images for the model you pick in GET /v1/videos/models, and review the result for shape drift; a generated turn is an interpretation of the object, not its geometry.

For exact dimensions or back-side details, shoot or model the product properly. A generated spin cannot show what the photo never contained.
