Key facts
Vendor-reported facts are read from the linked vendor page on the date shown above; we did not run the model. Independently tested means we ran it; no fact on this page is. Editorial is our own classification, not a vendor claim. Where a linked page does not itself state a value, the row says so. How to read provenance.

What the sources say
These are claims from the linked pages, not our measurements.
- 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 on this page is Reported from the sources below. When we do test it, the scope will be stated here and in our test logs. See methodology.
Not verified, left out
We could not confirm these on a vendor page, so we do not state them.
- 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.
