Anecdote: Gemini 3.5 casually added a DROP TABLE for an actual production table in a system test.

It had previously attempted to create that table as part of the test setup, so it apparently concluded that it was a test table.

During human review, it explained that it had simply chosen a table name inspired by the codebase.

Another anecdote: Gemini is the only model that’s flat out lied to me, then accused me of lying when I provided evidence that it was wrong.

Many other models get things wrong, but Gemini is the only one to go on the defensive.
