## Vendor claims and neutral signals

- webAI reports 98.2 on MATH-500 and 81.6 on LiveCodeBench (verbose variant) for the 8.79B model. Vendor claim; we did not run it.

## Notes

- Ships as two variants, balanced (default) and verbose, plus GGUF builds from 4.98 GiB (Q4_K_M) to 16.38 GiB (F16).

## What we tested

Nothing yet. We have not run TwIL-8B ourselves, so every fact here is Reported from the sources below.

## Not verified, left out

- No hosted inference provider or price is listed; the model is weights-only on Hugging Face.
- Benchmark scores are webAI's own internal runs, and several were measured only on the verbose variant, so they are listed as vendor claims only.
