The journey of large language models (LLMs) is marked by both remarkable achievements and significant challenges. These challenges range from the intricacies of data management to the ethical and computational concerns surrounding their development and use.

Unfathomable Datasets

A primary challenge in developing LLMs is managing the enormity of pre-training datasets. These datasets have grown so vast that they exceed the capacity of human teams for quality-checking. This has led to reliance on heuristics for data filtering and sourcing, which can introduce biases and errors. Near-duplicates in data can degrade model performance, and benchmark data contamination—where training data overlaps with test sets—can lead to inflated performance metrics and misrepresent the model’s true capabilities. Additionally, the presence of Personally Identifiable Information (PII) in training data raises serious privacy concerns.

Tokenizer-Reliance

Tokenization, the process of breaking down text into smaller units or tokens, is essential for feeding data into LLMs. However, the necessity of tokenization introduces several drawbacks. The number of tokens required to convey the same information varies significantly across languages, which can make the use of LLMs unfair in terms of cost and performance across different languages. Additionally, tokenization schemes often struggle with non-space-separated languages like Chinese or Japanese, and greedy algorithms used in tokenization may favor languages with shared scripts, leading to suboptimal performance for low-resource languages.
