问题描述

在使用心跳机制时遇到一个问题:当后端模型切换后,即使切回原模型,输出风格仍然保持之前模型的特征。

具体场景

  1. 心跳机制原本使用 deepseek 模型
  2. 前几天 deepseek 服务中断,系统自动切换到 kimi 模型
  3. deepseek 恢复后,将模型切回 deepseek
  4. 问题:输出风格仍然保持 kimi 的特征,没有恢复 deepseek 的风格

临时解决方案

通过新建会话(new session)解决了这个问题,说明问题与会话状态/缓存有关。

疑问

为什么模型切换后,某些上下文或缓存没有被正确清理?这是否是预期的行为?

环境信息

  • OpenClaw 版本:4.2(后回退到 3.24)
  • 涉及模型:deepseek → kimi → deepseek
  • 触发场景:心跳机制(heartbeat)

建议

是否可以在模型切换时增加更彻底的状态重置,或者提供明确的缓存清理机制?

extent analysis

TL;DR

Implement a thorough state reset or provide an explicit cache clearing mechanism when switching models to prevent residual effects from previous models.

Guidance

  • Investigate the current state management and caching mechanisms in the heartbeat system to identify potential areas where model-specific data is not being properly cleared.
  • Consider adding a cache clearing step when switching models, ensuring that all relevant state and context information is reset.
  • Review the differences in behavior between the deepseek and kimi models to understand how their characteristics are being retained even after switching back to the original model.
  • Test the proposed solution by simulating model switches and verifying that the output style correctly follows the currently selected model.

Example

No specific code example can be provided without more information on the implementation details of the heartbeat system and the models involved.

Notes

The exact implementation of the state reset or cache clearing mechanism will depend on the specifics of the system architecture and the models being used. It may be necessary to consult the documentation for the OpenClaw version being used (currently 3.24 after rolling back from 4.2) for guidance on managing model state and cache.

Recommendation

Apply a workaround by implementing a manual cache clearing step when switching models, as the root cause of the issue seems related to incomplete state reset or caching. This approach can help mitigate the problem until a more permanent fix is available.
