> They do not beat opus on real-world usage

We have an internal eval that measures performance on tasks for a handful of embedded systems repos for our mmWave radios (mostly Rust, some C for microcontroller stuff). Qwen3.6-27B scores only 4% lower for pass@1, n=250 compared to Opus-4.8.

For the labeled dataset, the average PR size they're being measured against is around 1.5k SLOC.

This is very much "real-world usage" for us. The sort of change sets that come in daily/weekly and are solving non-trivial issues in the respective codebases.

As is usually the case, the most broad claims from both the labs and from the consequent pushback are talking past each other.
