I can see the issue clearly now! In the verbose output, you can see:                                                                               

                                                                                                                                                   
 streaming: true                                                                                                                                   
                                                                                                                                                   

This confirms that despite your attempts to disable streaming via --no-stream or config file settings, aider is still running with streaming       
enabled.                                                                                                                                           

This appears to be a bug in aider v0.86.2. The --stream/--no-stream flag or the stream: false config setting is not being properly respected.      

What you should do:

    • Model: claude-sonnet-4-5                                                                                                                     
    • Issue: --no-stream flag and stream: false config are ignored                                                                                 
    • Evidence: verbose output shows streaming: true despite settings                                                                              
    • Include the verbose output fragment you just showed                                                                                          
 2 Workaround: Unfortunately, there doesn't appear to be an easy workaround if the command-line flag, config file, and environment variable are all
   being ignored. You might need to:                                                                                                               
    • Wait for a fix in the next version                                                                                                           
    • Try downgrading to an earlier version if streaming is critical for your use case                                                             
    • Check if there's already an issue filed and add your report there

This is definitely a bug that should be fixed - the setting is clearly documented but not working as expected.
