Foveance: LLM Context Compression Based on Future Importance
KrakenJiuJitsu · reddit · 2026-07-06
Foveance is an open-source Python library that processes long LLM conversation histories differently from truncation or summarization. It allocates context space based on the anticipated importance of future prompts rather than simply keeping the most recent messages. Its core argument is that important information often gets buried under irrelevant history.
The project can be used as a Python library, an OpenAI/Anthropic/Ollama compatible proxy, or as a wrapper for tools like Claude Code and Codex without modifying application code. It includes comparisons with solutions like LLMLingua-2 and provides reproducible benchmark scripts and CSV result files.
