bunpav vs Sloyd
bunpav vs Sloyd: unlimited parametric generation vs. AI mesh gen
Sloyd's pitch is unlimited generations on a free plan, built on parametric/procedural generators you can visually tweak — a genuinely different paradigm from most AI mesh tools. bunpav trades that for a wider raw export range and photo-to-mesh generation, but is still in private beta. Here's an honest, dimension-by-dimension look at both.
quick answers
The short version
What makes Sloyd different from most AI 3D generators?
Sloyd is built on parametric, procedural generators rather than a pure diffusion mesh pipeline — you can visually adjust the parameters behind a generated model instead of only prompting again. Sloyd also self-describes as "the only AI 3D Model Generator with unlimited generations," a claim worth noting is Sloyd's own marketing rather than an independently verified benchmark.
Does Sloyd really have no credit limit?
Its free Starter plan is built around unlimited generations rather than a metered credit pool, which is the closest philosophical cousin to bunpav's free Primitive Lab studio. bunpav's paid tiers use prepaid credit packs instead, shared across text-to-3D and image-to-3D.
Which tool exports more formats?
bunpav — GLB, FBX, OBJ, USDZ, and STL. Sloyd exports GLB, OBJ, and STL only, with no FBX or USDZ, which matters if your pipeline depends on FBX for engine import or USDZ for Apple AR Quick Look.
Which one can I actually use today?
Sloyd — it's publicly self-serve with a free plan today. bunpav is still in private beta behind a waitlist, so if you need a working tool this week, Sloyd is the practical option in the meantime.

Full comparison
| Dimension | bunpav | Sloyd |
|---|---|---|
| Availability | Private beta, waitlist-gated | Publicly self-serve today, free Starter plan |
| Generation paradigm | AI mesh generation from text prompt or reference photo | Parametric/procedural generators with visual parameter editing, plus image-to-3D |
| Generation limits | Prepaid credit packs, shared across text-to-3D and image-to-3D | Self-reported unlimited generations on the free Starter plan |
| Rigging & animation | Auto-rig humanoid/creature skeleton in the same generation pass | Auto-rigging and animation offered (self-reported by Sloyd) |
| Export formats | GLB, FBX, OBJ, USDZ, STL | GLB, OBJ, STL only — no FBX, no USDZ |
| Paid pricing | Prepaid packs: $9/100, $39/550, $89/1,500 credits, no subscription | Plus $11-15/mo, Pro $50/mo, Studio & Enterprise custom pricing |
| API / SDK access | Not currently offered | API/SDK and runtime generation available for larger teams |
A real capture of bunpav's own parametric studio, Primitive Lab — the closest thing bunpav has to Sloyd's unlimited, slider-driven generation model.
where bunpav wins
A wider export range
GLB, FBX, OBJ, USDZ, and STL cover engine import, Apple AR Quick Look, and 3D printing. Sloyd's GLB/OBJ/STL trio leaves out FBX and USDZ entirely.
Photo-to-mesh from a reference image
bunpav turns a reference photo into a textured, game-ready mesh directly. Sloyd's image input analyzes shape and proportions to inform a parametric generator rather than reproducing the photo's surface as a mesh.
where Sloyd wins
Unlimited generations, no meter
Sloyd's free Starter plan is built around unlimited generations rather than prepaid credits — useful for heavy iteration without watching a balance, and the closest thing in this category to bunpav's own free Primitive Lab studio.
A genuinely different generation paradigm
Parametric, procedural generators mean you can visually tweak the underlying parameters of a model instead of only re-prompting — a different workflow than most AI mesh generators, including bunpav.
who should pick which
Match the tool to the job
Pick Sloyd if
You want a free plan with no credit meter, like the idea of adjusting a model's underlying parameters visually, and don't need FBX or USDZ in your export list.
Join the bunpav waitlist if
You want FBX and USDZ alongside GLB, OBJ, and STL, prefer prepaid credits over a subscription, and can wait on beta access to open up.
faq
Questions, answered
What is the main difference between Sloyd and bunpav?
Sloyd is built on parametric, procedural generators with visually adjustable parameters and a free unlimited-generation Starter plan, publicly available today. bunpav generates textured meshes from a text prompt or reference photo, auto-rigs in the same pass, and exports a wider range of formats (including FBX and USDZ), but is still in private beta.
Is Sloyd's "unlimited generations" claim independently verified?
No — it's Sloyd's own marketing description ("the only AI 3D Model Generator with unlimited generations"). It's worth checking Sloyd's current pricing page for any fair-use limits before planning heavy production usage around it.
Why does bunpav support FBX and USDZ when Sloyd doesn't?
It's a straightforward format-range difference: Sloyd currently exports GLB, OBJ, and STL. bunpav adds FBX (common for game-engine pipelines that don't take GLB well) and USDZ (Apple AR Quick Look) alongside GLB, OBJ, and STL.
Does bunpav have anything like Sloyd's parametric editing?
No. bunpav's generation pipeline produces a finished textured mesh from a prompt or photo rather than exposing procedural parameters you can adjust after the fact. If parametric control over the underlying generator matters to your workflow, that's a genuine Sloyd strength.
Can I sign up for bunpav today the way I can with Sloyd?
Not yet. bunpav is in private beta behind a waitlist at bunpav.com. Sloyd is publicly self-serve with a free plan right now — a real, current gap worth knowing before you plan a project timeline around bunpav.
