Besides being an image generation site, Tensor.art is also a useful website for downloading user-trained Stable Diffusion models, which are needed by anyone running a Stable Diffusion interface on their own computer. This combination of features makes Tensor.art a head-to-head competitor with Civitai, which is even more famous as a model download site.
The wealth of models, and sample art for each model, are a great resource in Tensor.art. Different models work best with different settings (for Sample Steps, CFG Scale, and Sampling Method), but a great way to start your generations is to find a model you like (in the Models section, filter for SDXL for the best choice of Checkpoint models) and find an example image you like alongside the model.
Click on a sample image, and you'll see the prompt and settings used to create that image. If you just press the "Remix" button, the prompt and settings used to create the image will be copied into your Create control panel, so you're ready to generate a new image using those settings. Of course, you can change or replace the prompt. to make your own images, but learning from examples you like is a terrific way to get started.
When generating images in SDXL Stable Diffusion models, Tensor.art lets you type any prompt you want, with no filtering of NSFW content. Tensor.art also includes a way of using the newly released Stable Diffusion 3, but that comes with strict limitations on content, as well as costing far more points than standard generations. (These generation are actually being done by Stability AI, so they cost money and you have to follow their rules.) However, this is a full version of Stable Diffusion 3, not the more limited "Medium" version that was just released to the public, so you will get different and possibly much better images out of it.
While the restrictions and high price of SD3 might be a turn-off, you can already see huge improvement in prompt adherence between SDXL and SD3. Here is output from the following complex prompt, which SDXL had trouble with time after time, and SD3 can consistently match:

When you use Tensor.art for free, you can generate SDXL images at the same resolutions supported by Civitai, with both giving you output near the base resolution of the model. Even with the free generations, Tensor.art has the advantage of including adetailer, to automatically add more detail and refinement to faces, hands, or people in the scene.
If you subscribe to Tensor.art's Pro plan (starting at $9.90 per month) then Tensor.art has a huge advantage over other online Stable Diffusion image generator in resolution. You can use the "Hires.fix" option to generate your image at 2x or more the original resolution, enormously increasing the amount of detail in the scene. (This isn't just upscaling, it's actually computing more detail according to your prompts.) This puts Tensor.art well ahead of any paid level of service from Civitai or even from Mage.space, which caps the resolution lower than this.
Tensor.art is packed with features. It can do inpainting, so after you generate an image you can just select an area of the image, and then do a new generation replacing just that area. It also allows detailing as a post-process, to add detail to faces in your image after you have generated it.
Image-to-Image is one of Tensor.art's most powerful features, one of the things from local Stable Diffusion interfaces that I miss the most when using other online image generators. Image-to-Image lets you create an image, and then re-generate it with a different prompt, changing the style or contents of the image in an endless number of ways. See the sequence below as an example.
Overall Tensor.art seems like a winner. With higher resolution available, adetailer, and a great selection of Checkpoint models and LoRAs, Tensor.art seems like a top choice as a free image generator or as a low cost paid package.
