An Empirical Cost Attribution of Context-Compression Gateways in Multi-Turn Coding Agents

This work instrument a production compression gateway between coding agents and frontier LLMs, and decompose the token bill of real sessions into three independent levers: tool-schema filtering, content compression of file reads and tool output, and history summarization, which distill the results into an actionable re...

Paritok-4B: Intent-Conditioned Context Compression for Coding Agents

This work presents Paritok-4B, a 4B LoRA compressor for coding-agent trajectories built on two commitments, and distil a gpt-4.1-mini teacher over 67,074 real OpenHands trajectories into 40,606 validated examples and fine-tune Qwen3-4B.
