Leonardo.Ai vs Tensor.Art

Two fact sheets from our own research, side by side — pricing, platforms, API access and status re-checked by us rather than quoted from the vendors.

The short answer

Free plan: Both have one
Public API: Both have one
Best fit: Leonardo.Ai: Game and product teams that need consistent assets from a fine-tune they control · Tensor.Art: People who want to run a specific community LoRA without setting up a local Stable Diffusion install
Platforms: Leonardo.Ai: Web, iOS, Android · Tensor.Art: Web, iOS
Trust score: About even — Leonardo.Ai 87, Tensor.Art 88

What our research says

Leonardo.Ai

Leonardo is the generator to pick when you need control over the model rather than one house style, and it is the only major one with a real API and custom training. Token accounting is the tax you pay for that flexibility.

Pros

Large library of fine-tuned model presets instead of a single opinionated model
Custom model training on your own images is available without an enterprise contract
A genuine documented API, which the obvious competitor still does not have
Free tier of 150 daily tokens is enough to evaluate properly

Cons

Token costs differ by model, resolution and feature, so per-image cost is hard to predict
150 free tokens go in roughly ten generations
Concurrency and queue position are tier-gated, so cheap plans wait
Roadmap now serves Canva's product priorities, not standalone power users

Tensor.Art

The draw is the library, not the generator: hundreds of thousands of community checkpoints and LoRAs you can run without a GPU, plus a node editor for people who outgrow the prompt box. Credits are the real currency and they expire, so heavy users end up buying packs on top of the subscription.

Pros

Very large public library of checkpoints and LoRAs runnable in the browser
ComfyFlow node editor for multi-step pipelines, not just single prompts
Free tier resets a daily credit allowance rather than expiring after a trial
API keys issue instantly and bill from the same credit balance

Cons

Credits do not roll over, so an idle month is money lost
Cloudflare blocks automated access, which also complicates any scripted use of the site itself
Model licensing is the uploader's business, which pushes the rights question onto you

Which one fits

Choose Leonardo.Ai if you need

Game and product teams that need consistent assets from a fine-tune they control
Anyone who wants generation, canvas editing and upscaling in one place
Developers who need image generation behind an API rather than a chat window
Users who want to train a model on their own reference set

Choose Tensor.Art if you need

People who want to run a specific community LoRA without setting up a local Stable Diffusion install
Model authors looking for somewhere to publish and get their checkpoints used
Developers who need hosted open-weight image models behind a REST call
