Shap-E by OpenAI
Pros
- + Completely free under MIT — weights, code, and commercial use rights included
- + Generates 3D objects in seconds per sample on a single GPU; iteration is cheap in my testing
- + Dual representation output (textured mesh and NeRF-compatible implicit function) is technically elegant
- + The repository is genuinely approachable: self-contained notebooks, sensible defaults, quick setup
- + Well-documented, unusually honest model card that states its failure modes up front
Cons
- - Output is research-grade: rough edges, holes, blurry textures — OpenAI's model card admits samples are below professional asset quality
- - Multi-object prompts, attribute binding, and requested object counts fail often; composition is a structural weakness
- - No UI, hosted option, support, retopology, texturing tools or roadmap — everything past generation is your problem
- - The repository has been static since 2023 with no releases; the field has moved well past it
- - Image conditioning only works reliably on synthetic renderings, not real photographs
Luma
Pros
- + One credit balance covers Luma's Ray3.2/Ray3.14/Uni-1 plus Veo 3.1, Kling 3.0, Seedance, Flux 3, and ElevenLabs audio — cheaper than two or three separate subscriptions if you actually use multiple models
- + Ray3.2 outputs 1080p with 16-bit HDR, which in a third-party scene test produced the most atmospheric shot among the models compared
- + Credit refunds on errored generations, top-up packs ($4 per 1,200 credits) that roll over for 12 months, and commercial rights that survive cancellation
- + Sensible draft economics: 540p or Draft quality runs 20-100 credits per 5-second clip, so Plus's 10,000 credits buys 200-500 iterations before polish
- + Separate API with per-clip pricing (about $0.30 per 5-second 720p Ray3.2 clip) that roughly matches app economics at full utilization
Cons
- - No free tier and no unlimited plan — entry is $25-30/month and the old Dream Machine Unlimited tier is gone
- - Credit costs vary more than 10x across models: a 5-second 1080p Ray3.2 take is 400 credits while a Veo 3.1 second is 280, so plan allowance means little without a budget
- - No official Android video app, and a fake 'Luma Dream Machine' by another publisher charges $9.99/week on Google Play
- - iOS in-app purchase tiers still use old plan names (Lite, Unlimited) that do not match the current web plans (Plus, Pro, Ultra)
- - Ray3.2 has no native audio and clips cap at 10 seconds per generation; monthly credits expire unused
