+# Shap-E
+
+Shap-E introduces a diffusion process that can generate a 3D image from a text prompt. It was introduced in [Shap-E: Generating Conditional 3D Implicit Functions](https://arxiv.org/abs/2305.02463) by Heewoo Jun and Alex Nichol from OpenAI. 
+
+Original repository of Shap-E can be found here: https://github.com/openai/shap-e. 
+
+_The authors of Shap-E didn't author this model card. They provide a separate model card [here](https://github.com/openai/shap-e/blob/main/model-card.md)._
+
+## Introduction 
+
+The abstract of the Shap-E paper:
+
+*We present Shap-E, a conditional generative model for 3D assets. Unlike recent work on 3D generative models which produce a single output representation, Shap-E directly generates the parameters of implicit functions that can be rendered as both textured meshes and neural radiance fields. We train Shap-E in two stages: first, we train an encoder that deterministically maps 3D assets into the parameters of an implicit function; second, we train a conditional diffusion model on outputs of the encoder. When trained on a large dataset of paired 3D and text data, our resulting models are capable of generating complex and diverse 3D assets in a matter of seconds. When compared to Point-E, an explicit generative model over point clouds, Shap-E converges faster and reaches comparable or better sample quality despite modeling a higher-dimensional, multi-representation output space. We release model weights, inference code, and samples at [this https URL](https://github.com/openai/shap-e).*

+## Released checkpoints
+
+The authors released the following checkpoints:
+
+* [openai/shap-e](https://hf.co/openai/shap-e): produces a 3D image from a text input prompt
+* [openai/shap-e-img2img](https://hf.co/openai/shap-e-img2img): samples a 3D image from synthetic 2D image
+
+## Usage examples in 🧨 diffusers
+
+First make sure you have installed all the dependencies:
+
+```bash 
+pip install transformers accelerate -q
+pip install git+https://github.com/huggingface/diffusers@@shap-ee
+```
+
+Once the dependencies are installed, use the code below:
+
+```python 
+import torch
+from diffusers import ShapEPipeline
+from diffusers.utils import export_to_gif
+
+
+ckpt_id = "openai/shap-e"
+pipe = ShapEPipeline.from_pretrained(repo).to("cuda")
+
+
+guidance_scale = 15.0
+prompt = "a shark"
+images = pipe(
+    prompt,
+    guidance_scale=guidance_scale,
+    num_inference_steps=64,
+    size=256,
+).images
+
+gif_path = export_to_gif(images, "shark_3d.gif")
+```
