Why Claude Code Sessions Diverge: A Mechanism Catalog
The article discusses the divergence of Claude Code sessions and the mechanisms behind it. It highlights how different sessions can yield varying outputs despite using the same model and prompts. The author emphasizes the importance of understanding session-bound states and the implications for developers using hosted models.
- ▪Different sessions can produce different outputs even with the same model identifier and prompt.
- ▪Anthropic's postmortem revealed that multiple factors, including traffic slicing and session-sticky bugs, contribute to session divergence.
- ▪Longer sessions may accumulate more exposure to experimental changes, affecting reproducibility.
