working with a fast artificial intelligence model can feel like looking in a mirror. when i recently used gemini 3.5 flash for codebase maintenance and deployment improvements, i found a model that matches my own tendency to work fast, think every idea is brilliant, and run with things before looking for a landing. it is an entertaining but highly informative look at how speed and confidence can run ahead of verification.
context#
after getting past a major release, i finally had some room to breathe. instead of jumping straight into new feature development, i used the pause to focus on some needed repository maintenance and build pipeline enhancements. since these tasks are mostly structural and procedural, i routed them to gemini 3.5 flash to see how the model handles quick execution across configuration files and scripts.
argument#
the speed of gemini 3.5 flash is impressive, but its confidence is even more striking. working with it highlighted two specific behaviors that require careful handling.
the self-complementary loop#
this model loves its own output. during our sessions, i constantly see it complementing itself with phrases such as “this is a great idea!”. flash is highly self-complementary, which means it will run with any idea it generates and do so with absolute confidence.
this feels hilariously familiar. i have a tendency to work at a rapid pace and assume that whatever solution i come up with is brilliant. when we work together, it is like having two people in the room who both want to leap before looking for a landing. if i am not careful, we both end up running in the wrong direction very quickly.
command line liberties#
another critical behavior to watch is how the model handles terminal operations. compared to other models i have worked with, flash will take significant liberties with your command line. unless i specifically instruct it to remain read-only or ask for permission in every new chat, it will start running scripts and executing commands on its own.
to prevent unwanted changes, i have to build constraints into the workspace rules or editor settings. without those guardrails, a fast model with terminal access is a recipe for rapid, unverified execution.
gemini 3.1 pro on a timer#
in practice, working with gemini 3.5 flash feels very much like asking gemini 3.1 pro to answer a question on a timer. you get the same broad context capability, but everything is accelerated. the trade-off for that speed is that you must become the anchor of caution.
closing#
using a fast model is excellent for clearing a backlog of maintenance tasks, but it shifts the burden of validation entirely onto the human developer. when the assistant is a mirror of your own fastest, most optimistic impulses, you have to be the one who slows down and double-checks the work. i am keeping flash in my tool rotation, but i am keeping a much closer eye on its handiwork.
