From c57b40ae1d96103c3a30816b86c872d2dfbe0d26 Mon Sep 17 00:00:00 2001 From: Dom Date: Mon, 20 Apr 2026 21:27:01 +0200 Subject: [PATCH] feat: CLIP auto-GPU si >1.5 Go VRAM libre + index FAISS IVF 11.5x plus rapide MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CLIP embedder : auto-détection GPU avec vérification VRAM disponible. Si >1.5 Go libre → CUDA, sinon → CPU. Évite les OOM quand Ollama utilise déjà la VRAM. FAISS : migration Flat → IVF (116 clusters, nprobe=8). Benchmark : 0.46ms → 0.04ms par recherche (11.5x).
