Google’s CoLT5 Processes Extremely Long Inputs via Conditional Computation

One of the highlights of OpenAI’s GPT-4 large language model (LLM) is its expanded context window size of 32,000 tokens (about 25,000 words), which enables longer input sequences and conversations than ChatGPT’s 4,000 token limit. While expanding the processing capacities of transformer-based LLMs in this way is beneficial, it is also computationally costly due…
