 ## [Unreleased]
 
+### Fixed
+
+- Fixed `deepseek-v4-pro-0813` surfacing from Alibaba Token Plan discovery with `contextWindow`/`maxTokens` of `null`. The dated DeepSeek V4 Pro snapshot was missing from `ALIBABA_TOKEN_PLAN_DISCOVERED_MODEL_LIMITS`, so unlike its `deepseek-v4-flash-0731` sibling it fell through to unknown limits ([#8847](https://github.com/can1357/oh-my-pi/issues/8847)).
+
 ## [17.3.6] - 2026-08-17
 
 ### Changed
