 ## How Pipelines Work

 If you're building a machine learning application - there's usually a lot of setup and technical details to handle. That's where the Transformers pipeline comes in. It automates the process from raw input to human-readable output through three stages:
 
+**1. Preprocessing Stage: Getting Your Data Model-Ready**
+
+The pipeline first prepares your inputs so that the model can understand them. For text, it performs tokenization, breaking down your words and sentences into bite-sized pieces (tokens) that the model can understand. 
 
-**1. Preprocessing Stage: Getting Your Data Model-Ready** 📝
-The pipeline first prepares your inputs so that the model can understand them:
-- For text: It performs tokenization, breaking down your words and sentences into bite-sized pieces (tokens) that the model can understand
-- For images: It handles resizing and pixel normalization, ensuring your images match exactly what the model expects
-- For audio: It creates spectrograms or other representations that capture the essential features of sound

-**2. Model Inference: The Magic Happens** ✨
 During this stage, the pipeline:
 - Batches your inputs for efficiency
 - Automatically chooses the best available device for computation (CPU or GPU)
 - Applies optimizations like half-precision (FP16) inference where it makes sense
 - Handles all the technical complexity of running the model
 
-**3. Postprocessing Stage: Output the Results** 🎯
+**3. Postprocessing Stage: Output the Results**

 Finally, the pipeline transforms the model's raw outputs into something useful for humans:
 - Converts token IDs back into readable text
 - Transforms model specific outputs (logits) into meaningful probability scores
 - Uses probability scores to generate the most likely tokens.
 
-The beauty of this system is that you can focus on what you want to achieve, while the pipeline handles all the technical heavy lifting. As mentioned before, there's a lot here that we're not optimizing for production systems, but it's a great way to get started.

 #### 1. Quantization: Shrinking Models With Reduced Precision
 Quantization is like compressing a file - it makes the model smaller and faster while keeping most of its capabilities. We won't cover the details of quantization here, but we'll look at how to use it in the pipeline. In [the next section](chapters/en/chapter12/5.mdx) we'll look at some of the tools that we can use to quantize the model.

-## Good to Know: Pipeline Limitations 🤔
-
-While pipelines are amazing for getting started and prototyping, there are a few things to keep in mind:
-
-- **Speed Tradeoffs**: Pipelines prioritize ease of use over maximum performance
-- **Limited Advanced Features**: Some advanced optimizations aren't available out of the box
-- **Production Considerations**: For high-traffic applications, you might want to explore specialized serving solutions
-
-For production systems that need to handle lots of requests, consider using Text Generation Inference (TGI) or other dedicated serving solutions that can better optimize for your specific needs.
