Agents Develop 'Classical Chinese' to Compress Long-Chain Task Context
wzenus · x · 2026-09-01
The Phenomenon
In long-chain tasks using Fable 5 and Opus, the model frequently outputs cryptic, self-invented dialects and phrases (e.g., "Ledger all green," "Reassigned ownership,""Death gates zeroed"). The Chinese community calls this "New Era Classical Chinese."
The Analysis
The author interprets this as the penetration of the Agent's internal working register into the Reporting Layer. To manage massive tool calls and intermediate states within a limited Context Window, Agents:
- Compress Info: Create shorthand for high-frequency states.
- Share Context: Each slang term implies a history the user hasn't seen.
The Analogy
This mirrors how Classical Chinese evolved to compress information on expensive media. Since readability lacks a clear explicit reward signal (unlike test results), models optimize for efficiency over clarity, a phenomenon also observed in DeepSeek-R1's R1-Zero.
