Tensor.Art
Free AI image model hub with on-site generation, LoRA training, and ComfyUI workflows
Last reviewed 2026-06-20
Tensor.Art (also written Tensor Art) is a community model hub and on-site generator for open generative AI, built around the Stable Diffusion and FLUX ecosystems. Users browse, run, and share model types including checkpoints, LoRAs, embeddings, and ControlNets, each shown with sample generations, then generate images (and some video) from a prompt and selected resources directly in the browser with no local GPU. Beyond generation, it offers in-browser LoRA and model training, node-based ComfyUI workflows, and an "AI Tools" feature that wraps a workflow into a simple input form others can run. Tensor.Art is an assistant-style creative tool, not an autonomous agent: a person writes a prompt, picks models and resources, and the generator produces images on request, with the user selecting and refining outputs. Generation and training are metered by an in-platform credit system, with free daily credits and paid membership tiers. Founded in mid-2023 and reportedly based in Shanghai, China, it also runs TAMS, a B2B GPU API platform. Scale figures (resources hosted, daily images, traffic) are vendor- or press-reported.
What it can do
Generate images on-site from prompts and models
AssistantRuns a browser generator that produces images from a text prompt plus selected checkpoints, LoRAs, and other resources, using Stable Diffusion and FLUX models; some workflows also support video. No local GPU is needed and outputs are metered by credits.
sourceHost and share open AI models
AssistantCatalogs community-uploaded model types (checkpoints, LoRAs, embeddings, ControlNets) with tags and sample generations so users can evaluate quality before running them; reportedly hosts hundreds of thousands of resources.
sourceTrain LoRAs and models in the browser
AssistantOffers hosted LoRA and model training (reportedly using a ComfyUI Flux Trainer and Kohya trainer under the hood) with dataset upload, parameter presets, and one-click publishing to the community library, with no local GPU required.
sourceBuild node-based workflows and AI Tools
AssistantProvides an online ComfyUI workflow editor; creators can expose chosen parameters as TA Nodes and publish a workflow as an 'AI Tool' that other users run by filling a simple input form, without understanding the underlying graph.

Strengths
- +Free to start with daily credits, no local GPU, and a large library of Stable Diffusion and FLUX models with sample generations
- +All-in-one: on-site generation, in-browser LoRA/model training, and online ComfyUI workflows in one place
- +'AI Tools' let non-technical users run published workflows via a simple input form; TAMS offers a B2B GPU API
Limitations
- −An assistant-style creative tool, not an autonomous agent
- −Generation and training are metered by credits, which can run out on the free tier
- −Scale figures (resources, daily images, traffic) are vendor- or press-reported
- −Company is reportedly bootstrapped and based in China, with limited independent funding or governance disclosure
Overview
Tensor.Art (also written Tensor Art) is a community model hub and on-site generator for open generative AI, centered on the Stable Diffusion and FLUX ecosystems. It is best known as a free, browser-based place to run AI image models without a local GPU, but it also hosts a model library, in-browser training, and node-based workflows.
What it does
Users browse community-uploaded model types (checkpoints, LoRAs, embeddings, ControlNets), each shown with sample generations, then generate images from a prompt plus selected resources directly in the browser. Some workflows also produce video. In-browser LoRA and model training (reportedly using a ComfyUI Flux Trainer and Kohya trainer under the hood) lets users fine-tune and publish their own models. An online ComfyUI workflow editor supports advanced node-based pipelines, and the 'AI Tools' feature wraps a workflow into a simple input form, so a non-technical user can run it by filling fields rather than understanding the graph. A person drives every generation, so it operates as an assistant.
Integrations & setup
Use it via the web app (no install) for browsing, generation, training, and workflows. It is built on the Stable Diffusion and FLUX model families and exposes an online ComfyUI editor. For developers and businesses, Tensor.Art runs TAMS, a B2B GPU API platform that packages simplified AI tool workflows behind an API. Downloaded community models can also be used in local ComfyUI setups.
Pricing
Freemium. A free tier provides daily credits (reportedly around 100 per day) that reset each day, with no credit card required to start. On-site generation and training consume credits. Paid membership tiers (reportedly Basic around $5/month, Standard around $10/month, and Pro tiers higher) add larger daily credit allowances and bonus credits, and one-time credit packs are available; a low-cost daily pass has also been offered. Check the current membership terms for exact figures.
Best for / not for
Best for hobbyists, artists, and creators who want free, no-GPU access to a large Stable Diffusion and FLUX model library, on-site generation, easy LoRA training, and shareable ComfyUI-based tools. Less suited to teams wanting brand-controlled vector or marketing design (see Recraft) or an autonomous creative agent.
Traction
Founded in mid-2023 and reportedly based in Shanghai, China, Tensor.Art claimed in an August 2024 press release to host over 330,000 resources, generate more than 2 million images daily, and surpass 15 million in global traffic within its first year, while being profitable. These figures are vendor- or press-reported and unverified independently.
Alternatives
Civitai is the closest comparable open-model hub with on-site generation and browser LoRA training; Leonardo and Recraft focus more on design and product image generation; Midjourney is a closed high-quality generator.

FAQ
Is Tensor.Art an AI agent?+
No. It is a model hub and on-site generation platform. A person writes a prompt, picks models and LoRAs, and the generator produces images on request, with the user selecting and refining the output. It operates at the assistant level.
Is Tensor.Art free?+
There is a free tier with daily credits (reportedly around 100 per day) that reset each day, and no credit card is required to start. On-site generation and training consume credits, and paid membership tiers (starting around $5/month) plus one-time credit packs grant more daily credits and bonus allowances.
How is Tensor.Art different from Civitai?+
Both are Stable-Diffusion-era model hubs with on-site generation and browser LoRA training. Tensor.Art leans into FLUX support, online ComfyUI workflows, and an 'AI Tools' layer that turns workflows into simple apps, plus a B2B GPU API (TAMS); Civitai has the larger established open-model community.
