Closed as not planned

Description

@HongkaiSong

Description

After upgrading to OpenCode v1.15.13, when using the ACP integration with JetBrains IDEA AI Assistant plugin, every new chat session automatically resets to the default model configured in opencode.json. It does not remember the model that was selected in the previous conversation.

Plugins

JetBrains AI Assistant

OpenCode version

1.15.13

Steps to reproduce

  1. Open the AI Assistant chat panel in JetBrains IDEA
  2. Select any non-default model from the model dropdown list
  3. Send any message to confirm the model is active
  4. Click the "New Chat" button to create a new conversation
  5. Expected behavior:The new chat should automatically select the same model that was used in the previous conversation.
  6. Actual behavior:The new chat always resets to the default model specified in the opencode.json configuration file.

    This issue might be a duplicate of existing issues. Please check:

    If this is specifically caused by the ACP-Next/JetBrains integration (rather than a general model persistence issue), please clarify so maintainers can triage accordingly.
