You have one object in mind and two generators that both promise a textured 3D model from a prompt or a photo. Tripo vs Meshy is the choice most people hit once they get past their first AI mesh, and the marketing pages on both sides don't help much, because each one shows its best outputs.
This post compares the two versions that run in the studio here: Tripo H3.1 and Meshy 7.1. It is not a benchmark. It lays out what each model takes in, which settings you get, what comes back, and what a run costs, using the settings exposed in the studio and the vendors' own documentation. Credit figures are the ones at the time of writing; the Generate button always shows the current cost before you press it.
Tripo vs Meshy at a glance
| Tripo H3.1 | Meshy 7.1 | |
|---|---|---|
| Starts from | Text, or one photo | Text, one photo, or up to four photos (Multi Image) |
| Mesh controls | Geometry quality, face limit, quad switch, auto size | Mesh type, geometry detail, triangle or quad, target polycount, symmetry, remesh |
| Textures | On by default, PBR on by default, standard or detailed quality | On by default, PBR maps optional, texture prompt |
| Rigging and animation | Not available here | Auto-rig plus a preset animation |
| Credits per run | 65 | 172 untextured, 258 textured, more with a rig |
The short answer: Tripo H3.1 is the cheaper default for props and objects. Meshy 7.1 is the one to pay for when you need a rigged character, a mesh at a polycount you choose, or a model built from several photos.
Inputs: what each one can start from
Both run in Text to 3D and Image to 3D. In Text to 3D, Tripo takes a negative prompt as well, which helps when it keeps adding something you don't want, like a base under a statue. Meshy has an Expand prompt switch that rewrites a short prompt into a longer one, and a separate texture prompt for the surface.
For photos, the gap is wider. Meshy 7.1 comes in two image versions here: the normal one takes a single photo, and Meshy 7.1 Multi Image takes up to four, with slots for front, back, left and right. Tripo's developer docs say H3.1 also supports multiview input, but that mode is not wired into the studio, so here Tripo works from one photo. If the back of your object looks nothing like the front, a backpack or a shop sign, that matters more than any setting below.
Mesh and topology controls
Tripo H3.1
Tripo keeps it short. Geometry quality is standard or detailed. The face limit is optional and goes from 500 to 2,000,000; leave it empty and the model decides. A Quad mesh switch asks for four-sided faces instead of triangles, which is what you want for sculpting or rigging later. Tripo's docs cap quad output at 150,000 faces. Auto size scales the model to real-world dimensions, and for photos an Orientation option rotates the model to match the pose in the picture.
Meshy 7.1
- Mesh type: standard, lowpoly, or smart topology.
- Geometry detail: standard, 2K or 4K (Multi Image stops at 2K).
- Topology: triangle or quad.
- Target polycount from 100 to 300,000, default 30,000. With smart topology the studio caps it at 15,000, and leaving it at the default lets Meshy pick its own lower number.
- Symmetry: auto, on or off. Remesh is on by default.
- Pose: none, A-pose or T-pose, for characters you plan to rig.
Meshy gives you far more say over the mesh you get back. The cost is more ways to waste a run: symmetry on for an object that isn't symmetrical, or a 2,000 polycount on something with fingers. Tripo lets the model choose, which is the safer default when you don't know yet what the mesh is for.
Textures and materials
Tripo textures by default with PBR on, so you get colour plus roughness and metal maps without touching anything. Texture quality is standard or detailed. For photos, Texture alignment chooses whether the texture follows the original image or the generated geometry; the first keeps the look of the photo, the second can sit better on the shape where the model guessed.
Meshy also textures by default, but PBR maps are off until you switch them on. Its texture prompt lets you restyle the surface without changing the shape, say "weathered bronze" on a statue. You can also turn texturing off entirely, and here that changes the price: an untextured Meshy run costs 172 credits instead of 258. On Tripo, switching texture off doesn't lower the cost.
Rigging and animation: Meshy only
This is the clearest difference. Meshy 7.1 can add a skeleton to the model (Auto-rig) and then apply a preset motion from its animation library (Animate). You set the character's height for the rig, between 0.5 and 3 metres with 1.7 as the default, and pick the motion by its number in Meshy's library, from 0 to 696. The rig adds 42 credits to a textured run, the animation another 26, so a textured, rigged and animated character comes to 326 credits.
Read the limits before paying for it. Meshy's documentation says its auto-rig is built for humanoid characters with two arms and two legs, works best in a T-pose or A-pose with a clear gap between the limbs and the body, and that its API rigging isn't suited to untextured meshes or non-humanoid models. A dog, a robot with wheels or a lamp is not what this is for. Set Pose to A-pose or T-pose when you generate a character you plan to rig.
Tripo has no rig option in the studio. If you need a moving Tripo character, export the GLB, turn on the quad mesh when you generate, and rig it in Blender or another tool. That route costs you time instead of credits.
Credits per run
| Run | Credits |
|---|---|
| Tripo H3.1, any settings | 65 |
| Meshy 7.1, untextured (or text preview mode) | 172 |
| Meshy 7.1, textured | 258 |
| Meshy 7.1, textured and rigged | 300 |
| Meshy 7.1, textured, rigged and animated | 326 |
| For reference: Hyper3D Rodin | 86 |
| For reference: Hunyuan 3D Pro | 81 |
A textured Meshy model costs about four Tripo runs. That ratio is the whole decision for most props: if Tripo's first or second try is usable, Meshy can't pay for itself. Where Meshy wins on cost is when it saves you work afterwards, a rig you'd otherwise build by hand, or a mesh already at the polycount your game engine needs.
Looking for a Meshy AI alternative?
If you're searching for a Meshy AI alternative, the reason is usually cost or a result that keeps coming back wrong. Tripo H3.1 is the cheaper swap for objects and props. For a character or a product with a distinctive back, Hunyuan 3D Pro takes extra back, left and right photos for 81 credits plus an add-on. If you want a file you can print without converting, Hyper3D Rodin can write STL directly; our Hyper3D Rodin examples show what it makes from real photos.
One honest downside of using Meshy here instead of on Meshy's own site: you get the model and its settings, not Meshy's web app. Its docs describe tools around the model, such as a remesh step and an animation browser, which aren't part of the studio. What you get instead is all six 3D generators side by side on one credit balance, so you can try the same photo on Tripo and Meshy and keep the better one.
Which one to pick
- A prop, a product, a piece of furniture: Tripo H3.1.
- Several attempts to find a shape that works: Tripo, at a quarter of the price per try.
- A humanoid character that has to walk, wave or dance: Meshy 7.1 with Auto-rig and A-pose.
- A game asset with a fixed budget, say under 5,000 faces: Meshy with lowpoly or smart topology and a target polycount.
- Front, back and side photos of the same thing: Meshy 7.1 Multi Image, or Hunyuan 3D Pro.
- A single-colour 3D print: either, but with Meshy switch texturing off.
Our recommendation: start every object on Tripo H3.1 at 65 credits. Move to Meshy 7.1 only for one of the jobs Tripo can't do here, a rig, multiple photos or a set polycount, and budget 258 to 326 credits per attempt when you do. Whichever you use, the free 3D model converter turns the GLB into STL, OBJ or PLY in your browser.
The short version
Tripo H3.1: one photo or a prompt, few settings, textures and PBR on by default, 65 credits. Meshy 7.1: up to four photos, full control over mesh type and polycount, auto-rig and animation for humanoids, 172 to 326 credits depending on what you switch on. Default to Tripo, pay for Meshy when you need what only it does.
Both are on the 3D generation page, with the other four 3D models next to them.
