Just call a class.<br> </p> <div class="highlight js-code-highlight"> <pre class="highlight python"><code><span class="kn">from</span> <span class="n">rabbit_hole.executors</span> <span class="kn">import</span> <span class="n">T2IExecutor</span> <span class="n">exe</span> <span class="o">=</span> <span class="nc">T2IExecutor</span><span class="p">()</span> <span class="nf">exe</span><span class="p">(</span><span class="sh">"</span><span class="s">a photo of a rabbit in a field</span><span class="sh">"</span><span class="p">,</span> <span class="n">output_path</span><span class="o">=</span><span class="sh">"</span><span class="s">result.png</span><span class="sh">"</span><span class="p">)</span> </code></pre> </div> <h3> 🚀 What’s Next? </h3> <p>Rabbit-Hole is under active development.<br> Some recent additions:</p> <ul> <li>✅ SDXL + IPAdapter Plus support</li> <li>✅ ControlNet + Hint Image (Canny)</li> <li>✅ Upscaling by Model</li> <li>✅ LoRA composition</li> </ul> <p>Upcoming:</p> <ul> <li>🔄 RAG + LLM-powered image generation guidance</li> <li>🐍 CLI / REST API interface</li> <li>🧩 Tunnel Auto-generation from ComfyUI workflows</li> </ul> <h3> 🌟 Try it Out! </h3> <p>GitHub: <a href="https://github.com/pupba/Rabbit-Hole" rel="noopener noreferrer">https://github.com/pupba/Rabbit-Hole</a></p> <p>If you're building an AI image generation service, or want to take ComfyUI to the next level — <strong>give Rabbit-Hole a try</strong>.</p> <p>I’d love your feedback, issues, and stars! ⭐<br> Thanks for reading — see you down the rabbit hole.</p> programming opensource comfyui python
