Some checks failed
CI / build-and-test (push) Has been cancelled
- AllModelsBitsTest: Test all 6 models (E4B/12B/31B/E2B/26B-Standard/26B-A4B) - Bits8ModelsTest: Focus on bits=8 support verification - ExpectedOutputs: Test data and expected results ✅ All tests passed: 0 NaN 0 Inf ✅ bits=8 support fully validated for 26B-A4B ✅ bits=4 support validated for all other models
