<p>Algorithmically-generated AI science-fantasy artwork featuring a steampunk computer, created using the <a rel="nofollow" class="external text" href="https://github.com/CompVis/stable-diffusion">Stable Diffusion V1-4</a> AI diffusion model.

</p><p>A single 768x512 image was generated with txt2img using the following prompts:
</p><p><code>Prompt: steampunk gaming PC, copper pipes, mechanical gears, (steam escaping from valves), (office desk with CRT monitor and computer keyboard), highly detailed, intricate, high quality, digital painting</code>
</p><p><code>Negative prompt: none</code>
</p><p><code>Settings: Steps: 50, Sampler: Euler a, CFG scale: 7, Size: 768x512</code>
</p><p>Afterwards, the image was extended by 128 pixels on the left and right sides using two passes of the "Outpainting mk2" script within img2img. This was done using a setting of 100 sampling steps with Euler a, denoising strength of 0.8, CFG scale of 7, mask blur of 8, fall-off exponent value of 1.8, colour variation set to 0.03. This subsequently increases the image's dimensions to 1024x512, while also increasing the field of view compared to the originally generated image.
</p>
Then, three passes of the SD upscale script using "SwinIR_4x" were run within img2img. The first pass used a tile overlap of 64, denoising strength of 0.1, 150 sampling steps with Euler a, and a CFG scale of 7. The second pass used a tile overlap of 128, denoising strength of 0.1, 150 sampling steps with Euler a, and a CFG scale of 7. The third pass used a tile overlap of 256, denoising strength of 0.1, 150 sampling steps with Euler a, and a CFG scale of 7. This creates our final 8192x4096 image.
