a backend developer would tell you the backend is much more important to focus on, performance, security, data integrity etc. not losing or exposing customer data is a lot more important than what it looks like.
truth is, it's all still important, preferably no one is vibe coding any part of a serious product.
Deepseek manages to be ridiculously cheap and efficient with prompt caching, i spent 550M~ (1.9b input cache miss, 1.7b output) tokens and it cost me 5~ bucks, that would be ~150 bucks on Opus 5.5, if i ran that workload in parallel that would be $50 vs $1500, e.i. i wouldn't want to subagent heavily with anthropic models.
now imagine Kimi K4 or GLM 5.5 with those cost savings
in any case, I've been using open and closed models since sonnet 4, i remember when the best I could get was qwen 3 480b coder, you can definitely feel the gap closing going from that and GLM 4.5, to GLM 5.3, DeepSeek Flash V4.1, Kimi K3 etc, it's reached the point where i wish I had V4.1 at work, it's faster and bullshits me less when I use it in my personal projects. And I have unlimited access to fable 5.1
nothing on the fine print tells you what the weights are, you're just getting Fable 5, whatever that is
Opus 5 came out with better benchmark results than Fable, but it really did not feel better to use at all.
have him start with an overall design doc if his change is 15k, it's definitely worth a design doc.
and then have his contributions reviewed in pieces of 200-300 LoC PRs.
any other solution is trading stability and system knowledge, that's 15k LoC no one is truly familiar with, even if you do try to review it
