From 37d97224e77d7453bf06064d5d6c9a742529db52 Mon Sep 17 00:00:00 2001 From: MarkBase Admin Date: Wed, 24 Jun 2026 09:33:27 +0800 Subject: [PATCH] Add comprehensive bits=8 model testing suite MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - 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
