From 4454f685f59c98a5a7a478ca3d5c181a4007ff3f Mon Sep 17 00:00:00 2001 From: MarkBase Admin Date: Tue, 23 Jun 2026 20:48:29 +0800 Subject: [PATCH] Add complete model testing report (E4B, 12B, 31B, E2B) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Test Results Summary: - E4B-MarkBase: 42 layers, 2560 hidden, multimodal (Audio+Vision), 42.8 tok/s - 12B: 48 layers, 3840 hidden, pure text, ~26 tok/s - 31B: 60 layers, 5376 hidden, 64 heads, largest model, stable - E2B: 48 layers, 3840 hidden, per-layer architecture, Audio tower 12 layers Performance: - All models: 0 NaN (perfect stability) - Speed ranking: E4B > 12B/E2B > 31B - Capacity ranking: 31B > 12B/E2B > E4B Recommendations: - Multimodal → E4B-MarkBase (only option) - Speed → E4B-MarkBase (42.8 tok/s) - Quality → 31B (60 layers, highest capacity) - Balance → 12B or E2B - Code generation → Need specialized model Tests: 15/15 passed (0 unexpected failures) ---
