Livenerf – a benchmark for whether Opus 5.5 gets nerfed
github.com · 1 day on the radar
Where is the demand coming from?
Leans on the founder
The founder's audience is a large part of it. This is the read that decides whether the traction would transfer to you.
Roughly what does it earn?
Not disclosedNo basis to estimateWe do not publish a figure until we have something to base it on. When we do, the method that produced it is shown alongside the range.
Could you build it?
Yes, in about 3 days
Nothing patented, no network effect, and no proprietary data set standing in the way.
What it is
Livenerf is an open-source benchmark harness designed to detect whether Claude Opus 5.5 degrades after launch by running deterministic eval tasks hourly against the model and tracking drift statistically. The project launched on Hacker News with modest traction but appeals to a niche audience concerned about model capability changes post-release.
The one thing to knowThis is a monitoring/audit tool for a closed model, not a product with business defensibility or wedge opportunity, making it unsuitable for studio replication despite trivial buildability.
