The Mark IV Tank was a British armoured vehicle used extensively during World War I. Introduced in 1917, it was a major improvement over previous models, showcasing enhancements in armor, reliability, and firepower. Equipped with either machine guns (in the case of "Female" tanks) or 6-pounder cannons (for "Male" tanks), the Mark IV represented a critical step forward in tank design, becoming a symbol of early mechanized warfare.<h3 id="how-to-use">How to use</h3>This LoRA of a British Mark IV tank (1917) should be easy to use. You can keep the LoRA weight at 1, and you can invoke it with the trigger word <code>mkiv17</code> (meaning "mark IV 1917"). You can then personalize the tank by adding colour, camouflage, symbols, numbers etc in the prompt. For other parameters: Checkpoint should not matter, this model works as a realistic and illustrated concept. CFG should be kept around 7 but try not to go above 9. In terms of the Sampler, I use <code>DPM++ 2M Karras</code> 20 steps. In terms of Hires Fix, I use a 200% scale with <code>4x_NMKD-Siax_200k</code>, full steps (0), and 40% denoising. For Clip Skip I recommend 1 since it was trained with it. But you can experiment.<h3 id="training-information">Training information</h3><ul><li>30 images were used (only real photographs)</li><li>5 repeats per image, a batch of 2, 30 epochs (2250 steps)</li><li>Captioning with BLIP and manually corrected for each picture</li><li>Trained on Stable Diffusion 1.5</li><li>Clip Skip 1</li><li>62 DIM / 32 Alpha</li></ul>
