Researchers have explored the connection between learning, prediction, and compression for real-time text transmission using LLM-based entropy coding. They analyzed the trade-off between compression efficiency and transmission delay when a causal language model predicts symbols for encoding over fixed-rate channels. The study compared various coding schemes, including Huffman, arithmetic coding, and rANS, finding that Huffman is practical for over-provisioned channels due to its zero algorithmic delay, while arithmetic coding offers better compression at the cost of delay. These findings were validated across models ranging from GPT-2 (124M) to Llama 3.2 (3B), demonstrating that larger models improve compression and can alter the optimal coding scheme. AI
