Thanks a lot for Your help! The code you suggested works so far, that the SpotlightSearchTool() is invoked with returning a message in the console like: "📍 NativeSpotlightSearchTool: Completed with 82 total results, returning 15 items" However in some instances for reasons yet unclear to me, the execution stops here, not finishing the response still returning the error: "Playground has encountered an error Provided X.XXX tokens, but the maximum allowed is 4.096." , with the number X depending on the prompt. Also the workaround yet works only with the "guide: .focused())" option, not with ".complete" or ".none" .

Hello! Have to agree with the OP. The model seems to be tool hungry, simple prompts get a response asking for a tool or spewing JSON code.

Thx for your reply! Unfortunately your suggested procedure did not solve the issue. I filed a FB report under the number FB24079629.

Thx for filing this bug! This error already occurred during developer beta 3. After upgrading to developer beta 4 nothing changed. On beta 3 i already tried rebooting, changing general and Siri language settings, but nothing helped.
