Run it on your iron.
Same workload. Same 37.45 MiB buffer. Same 2-bit packed scan. Run the public CLI on your hardware, then put its number beside your current stack.

1. Run the test
Open a terminal and run the downloaded binary:
damnit-benchmark-cli.exe
It prints CPUID topology, arena allocation speed, single-thread and all-core AVX2 GB/s, and a scalar-vs-SIMD checksum. The invariant is 1945; a mismatch means the run does not count.
- Buffer: 37.45 MiB (39,269,171 bytes), filled from xorshift32.
- Work: the same 2-bit packed scan as the Damnit kernel, 5 samples x 8 passes, median.
- No model, weights, workspace code, installer or application link.
Reference run
Every published result has a record behind it: the machine, the load around the run, the exact binary hash and the checksum. This is the current published reference.
11th Gen Intel(R) Core(TM) i3-1115G4 @ 3.00GHz · 4 logical CPUs · 7.8 GiB · CPU load 28% before, 21% after · binary sha256 f8b3e97cd373…

Verify the download
Windows may hold an unsigned executable from a new publisher until it builds reputation. Do not trust the warning and do not disable Defender: check the bytes.
certutil -hashfile damnit-benchmark-cli.exe SHA256
This build is SHA-256 f8b3e97cd373f83b83f899e85268e7f1c81a3724dee577163da9a60d7c79edea · 458,240 bytes. If certutil prints anything else, do not run the file.
The CLI contains no network code, installer, service or registry writes. If Defender quarantines it, submit the hash as a false positive at Microsoft's file submission page and compare the file against the record above.
2. Compare
Compare your hardware
Run your current stack and the Damnit CLI on the same machine. Enter both throughput numbers; the comparison is arithmetic, not a verified benchmark.
3. Lease the kernel
If the Damnit result is the one you want to ship, choose a lease. The individual lease covers one machine; the commercial lease covers two. Both include the compiled Windows kernel and startup subscription verification. The kernel stops when the subscription is no longer active.
Running the public challenge does not require a licence. If you are an individual or a small team rather than a company, email aaron@damnit-ai.com and tell us what you want to build.
