In 2025, Large Language Models (LLMs) like ChatGPT and Claude 3.5 continue to be integral to AI workflows, yet they face challenges due to token limits, which restrict the amount of text they can process in one go. Despite advancements such as Gemini 1.5 Pro's ability to handle up to 1 million tokens, practical limitations persist, especially for applications requiring extensive document processing, like legal analysis or summarization. Solutions to these constraints include strategies such as chunking, summarization, semantic search, and Retrieval-augmented Generation (RAG) pipelines, which help manage and optimize token usage. Additionally, techniques like fine-tuning allow models to perform efficiently on specific tasks with less data, thus working within token limits. Developers use tools like Deepchecks LLM Evaluation to monitor and ensure models operate effectively without compromising quality, employing methods like truncation, chunk processing, and the removal of redundant terms to handle text input within these constraints.
