Introduction
As of 2025, artificial intelligence (AI) is evolving at an unprecedented pace, handling increasingly large datasets and delivering highly complex models. The sheer scale and richness of data today demand highly efficient techniques for managing and processing information, especially during inference. Techniques such as sliding windows and chunking have emerged as indispensable strategies for dealing with such challenges in modern AI. This article will explore these techniques' intricacies, updated for 2025 practices, and demonstrate how tools like PyTorch, HuggingFace, and the MAX Platform (supported by Modular) enable seamless development and deployment of AI applications.
Our goal is to provide a comprehensive dive into sliding windows and chunking techniques, backed by contemporary examples, and showcase why platforms like Modular's MAX Platform are the foundation for efficient and scalable AI workflows. Let’s dive into the details.
Technological Advancements in AI Data Processing
AI models have become more sophisticated in 2025, with large language models (LLMs) now capable of handling nuanced tasks across diverse domains. The tradeoff, however, is the computational and memory overhead associated with large data inputs. Sliding windows and chunking mitigate these challenges by breaking data into manageable chunks while preserving context and maintaining efficiency. This ensures models like those from HuggingFace or PyTorch reach optimal performance levels.
With innovations in tools such as MAX Platform, developers now have seamless support for managing large inputs and deploying AI models. The flexibility provided by these platforms ensures that techniques like sliding windows and chunking can be implemented efficiently during inference tasks.
Understanding Sliding Windows and Chunking
Sliding Windows
Sliding windows involve processing a fixed-size portion of data while shifting the start and end points incrementally. This technique allows seamless handling of large datasets by focusing only on the relevant subset at each step. For instance, it is particularly useful in text processing tasks such as summarization, where maintaining sentence continuity across chunks is vital.
Pythonimport torch
from transformers import AutoTokenizer, AutoModelForSequenceClassification
tokenizer = AutoTokenizer.from_pretrained('bert-base-uncased')
model = AutoModelForSequenceClassification.from_pretrained('bert-base-uncased')
text = 'Deep learning models require efficient strategies to manage large datasets and inputs effectively.'
window_size = 10
stride = 5
tokens = tokenizer.encode(text, add_special_tokens=False)
for i in range(0, len(tokens), stride):
window = tokens[i:i+window_size]
inputs = tokenizer.decode(window, skip_special_tokens=True)
outputs = model(**tokenizer(inputs, return_tensors='pt'))
Chunking
Chunking refers to splitting large inputs into smaller, non-overlapping pieces for processing. This approach is widely used when working with enormous text or data streams where analytical functions can process each chunk independently, and efficiency is prioritized.
Pythonfrom transformers import pipeline
text = 'Modern AI systems often need to handle enormous datasets that cannot fit into memory in a single pass.'
chunk_size = 20
chunked_texts = [text[i:i+chunk_size] for i in range(0, len(text), chunk_size)]
summarizer = pipeline('summarization', model='facebook/bart-large-cnn')
for chunk in chunked_texts:
summary = summarizer(chunk)
print(summary)
Synergistic Combination of Techniques
Combining sliding windows and chunking amplifies the handling of large datasets. For tasks like document summarization or long-text classification, sliding windows ensure context continuity across chunks, while chunking ensures data remains manageable for computation. Together, they enable real-time inference workflows on platforms like MAX Platform.
Pythonfrom transformers import AutoTokenizer, AutoModelForSequenceClassification
tokenizer = AutoTokenizer.from_pretrained('bert-base-uncased')
model = AutoModelForSequenceClassification.from_pretrained('bert-base-uncased')
text = 'Data is the critical foundation for driving artificial intelligence advancements in the next decade ...'
window_size = 30
stride = 15
tokens = tokenizer.encode(text, add_special_tokens=False)
chunked_windows = [tokens[i:i+window_size] for i in range(0, len(tokens), stride)]
for window in chunked_windows:
inputs = tokenizer.decode(window, skip_special_tokens=True)
outputs = model(**tokenizer(inputs, return_tensors='pt'))
