Long Context Fine-Tuning: A Technical Deep Dive

Long context fine-tuning has become increasingly important as large language models (LLMs) can now handle millions of tokens, enabling enterprise applications such as document analysis and summarization systems. However, implementing reliable long context LLMs is challenging due to performance degradation for context length thresholds much smaller than the maximum limit. Fine-tuning smaller models on longer contexts can enhance their performance at a fraction of the cost. The Together AI platform now supports fine-tuning on context lengths up to 32k tokens, with plans for even longer sequence lengths. This approach is particularly valuable for enterprise applications where data privacy and ownership are crucial considerations.
