- Best for: General-purpose CoT compression
5. Adaptive Compressor
- Compression: 4.17%
- Importance-based message scoring (0-10 scale)
- Dynamic compression ratios
- Best for: Mixed-importance content
6. Dialogue-Focused Compressor
- Compression: ~0% (preservation mode)
- Optimized for Q&A and conversation
- Preserves user queries and key responses
- Best for: Interactive dialogue scenarios
7. Thinking Strip Compressor
- Compression: ~0%
- Removes
<thinking>...</thinking>blocks - Minimal impact on test data
- Best for: Explicit reasoning chain removal
Configurable Variants (8 presets)
Fine-tune compression with environment variables:

Usage
High-Compression (99% reduction)
from performance_focused_compressor import compress_messages
messages = [
{'role': 'user', 'content': 'Your very long context here...'},
{'role': 'assistant', 'content': 'Long response...'}
]
compressed = compress_messages(messages)
# Returns ~1% of original size with start/end preserved
Code Debugging (83% reduction)
from code_focused_compressor import compress_messages
# Preserves stack traces, errors, code blocks
compressed = compress_messages(debug_messages)
Extreme Compression (95% reduction)
from aggressive_hybrid_compressor import compress_messages
# Extracts only critical information
compressed = compress_messages(agent_logs)
