A new paper from NVIDIA demonstrates that aggressive context compaction techniques can significantly reduce the token usage of large language models without substantial accuracy loss. The research shows that models like Claude Opus 4.5 can maintain high performance on tasks such as SWE-bench Verified and Terminal-Bench, even when their context window is drastically reduced from tens of thousands to a few thousand tokens. This method involves carrying a summarized state rather than the full conversation history, which also offers considerable cost savings, especially for open-weight models where later tokens are more expensive.
