Gemma 4 12B first coding agent test on a 4080 Super

Just threw the new Gemma 4 12B into VSCodium with the Pi Agent extension to see how it handles tools, and it nailed the test on the first try. I gave it a prompt to write a Python script that reads logs line-by-line, grabs the error modules, and dumps the counts to a JSON file. I also told it to make its own mock log data and run a live terminal test to verify the results.

Instead of just spitting out a block of code for me to copy and paste, the agent actually went to work. It created the script, populated a dummy app.log file with a mix of random logs, opened up a terminal shell to run the code, and verified the output with zero bugs or path errors.
