# qwen-image-bench — flukethoughts/Qwen-Image-Bench-NVFP4 on ana-ml2 GPU 1, # REPLACING qwen3.6-35b-a3b (operator 2026-06-19). Qwen's text-to-image quality # JUDGE model (vision-language, NVFP4 weights / vision tower bf16). NOT generative — # it scores T2I outputs on 5 dims (overall quality, prompt match, aesthetic, LoRA # activation, confidence). # # Arch: Qwen3_5ForConditionalGeneration (dense Qwen3.5 hybrid SSM+attn + vision), # ~17B / ~20GB NVFP4. VISION-INTACT → served as multimodal; NO text-only patch # (unlike the qwen3.5-122b gen model, which had text-only weights). vLLM # production-validated per the model card. # # ⚠️ qwen3.6-35b-a3b was arbo's hero-judge (comfy-dev consumer). Downing it breaks # arbo's judging until comfy-dev repoints to qwen-image-bench (different I/O — a # 5-dim verdict vs a general VL judge). comfy-dev notified. # # DISPLACEMENT: GPU 1 is shared (granite/selene/embed/rerank/reward). qwen3.6 used # util 0.34 (~33GB); down it first, then this fits at util ~0.22 (~21GB). REVERT = # down this, `up -d` the qwen36 stack. # # Tunables in .env. name: qwen-image-bench services: vllm-qwen-image-bench: image: ${QIB_IMAGE:-vllm/vllm-openai:latest} container_name: ${QIB_CONTAINER_NAME:-vllm-qwen-image-bench} restart: unless-stopped ipc: host ports: - "${QIB_PORT:-8014}:8000" volumes: - /tank/aimodels/huggingface:/hfcache - /tank/aimodels/qwen-image-bench-nvfp4:/model:ro environment: - HF_HOME=/hfcache - HF_HUB_CACHE=/hfcache/hub - VLLM_API_KEY=${API_KEY:-} command: - /model - --served-model-name - qwen-image-bench - --host - 0.0.0.0 - --port - "8000" - --gpu-memory-utilization - ${QIB_GPU_MEM_UTIL:-0.32} - --max-model-len - ${QIB_MAX_MODEL_LEN:-32768} - --max-num-seqs - ${QIB_MAX_NUM_SEQS:-8} - --trust-remote-code - --dtype - auto - --enable-prefix-caching deploy: resources: reservations: devices: - driver: nvidia device_ids: - "${QIB_GPU_ID:-1}" capabilities: - gpu healthcheck: test: ["CMD", "curl", "-f", "http://localhost:8000/health"] interval: 30s timeout: 10s retries: 3 start_period: 600s networks: - tnet labels: - homepage.group=AI - Eval & Retrieval - homepage.name=Qwen-Image-Bench (T2I judge, NVFP4) - homepage.icon=mdi-image-check - homepage.description=Qwen text-to-image quality judge (NVFP4, vision-intact) on ana-ml2 GPU 1 - homepage.href=http://10.250.50.54:${QIB_PORT:-8014}/docs networks: tnet: name: traefik-net external: true
