You'll notice there is no "ball" in the image! Let's use compel to upweight the concept of "ball" in the prompt. Create a [`Compel`](https://github.com/damian0815/compel/blob/main/doc/compel.md#compel-objects) object, and pass it a tokenizer and text encoder:  
```py
from compel import Compel

compel_proc = Compel(tokenizer=pipe.tokenizer, text_encoder=pipe.text_encoder)
```  
compel uses `+` or `-` to increase or decrease the weight of a word in the prompt. To increase the weight of "ball":  
<Tip>  
`+` corresponds to the value `1.1`, `++` corresponds to `1.1^2`, and so on. Similarly, `-` corresponds to `0.9` and `--` corresponds to `0.9^2`. Feel free to experiment with adding more `+` or `-` in your prompt!  
</Tip>  
```py
prompt = "a red cat playing with a ball++"
```  
Pass the prompt to `compel_proc` to create the new prompt embeddings which are passed to the pipeline:  
```py
prompt_embeds = compel_proc(prompt)
generator = torch.manual_seed(33)

image = pipe(prompt_embeds=prompt_embeds, generator=generator, num_inference_steps=20).images[0]
image
```  
<div class="flex justify-center">
<img class="rounded-xl" src="https://huggingface.co/datasets/hf-internal-testing/diffusers-images/resolve/main/compel/forest_1.png"/>
</div>  
To downweight parts of the prompt, use the `-` suffix:  
```py
prompt = "a red------- cat playing with a ball"
prompt_embeds = compel_proc(prompt)

generator = torch.manual_seed(33)

image = pipe(prompt_embeds=prompt_embeds, generator=generator, num_inference_steps=20).images[0]
image
```  
<div class="flex justify-center">
<img class="rounded-xl" src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/compel-neg.png"/>
</div>  
You can even up or downweight multiple concepts in the same prompt:  
```py
prompt = "a red cat++ playing with a ball----"
prompt_embeds = compel_proc(prompt)

generator = torch.manual_seed(33)

image = pipe(prompt_embeds=prompt_embeds, generator=generator, num_inference_steps=20).images[0]
image
```  
<div class="flex justify-center">
<img class="rounded-xl" src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/compel-pos-neg.png"/>
