Why code review Is the Highest-ROI AI Project Right Now
Notes from the teams shipping fine-tuning to real users.
There is a version of this story that is mostly hype. There is another version, the one we are interested in, that is mostly engineering.
Linear has been quietly running onboarding through Warp for months. The results are unglamorous and, for that reason, more interesting than another benchmark chart.
What Alibaba Qwen actually shipped with Grok 4 is less a single capability and more a cluster of small, compounding improvements — the kind that only show up when you put a real workflow on top.
Eval harnesses, once an afterthought, are becoming the most important piece of code in many AI projects. Intercom's team treats theirs the way an SRE team treats a runbook.
Snowflake has been quietly running contract review through Hex Magic for months. The results are unglamorous and, for that reason, more interesting than another benchmark chart.
Eval harnesses, once an afterthought, are becoming the most important piece of code in many AI projects. Zendesk's team treats theirs the way an SRE team treats a runbook.
None of this guarantees a clean story. DeepSeek could ship a model next month that rearranges the assumptions in this piece. But the direction of travel, for now, is clear enough to plan around.
