[cost\_intel] Latency cliff makes reasoning models unusable for real-time collaborative editing or multiplayer sync logic

Use deterministic operational transformation \(OT\) algorithms or CRDTs for collaborative state sync; use instruct models only for high-level conflict resolution suggestions when automatic merge fails.

Journey Context:
Collaborative editing requires <50ms latency for conflict resolution. Reasoning models take seconds to analyze complex merge conflicts, breaking real-time collaboration flow. Common mistake: Using LLMs to automatically resolve every edit conflict in a multiplayer text editor. Alternative considered: Hybrid approach where reasoning models pre-compute merge strategies, but this fails because edit patterns are unpredictable and context-dependent. Quality degradation signature: Reasoning models introduce semantic changes during "resolution" that alter user intent, whereas OT algorithms preserve intent exactly. Cost analysis: Real-time sync handles thousands of ops/sec; reasoning model costs would be $1000s per hour per document. The fix relies on proven distributed systems algorithms for speed/correctness, reserving AI for offline conflict review when human intervention is already required.
