Running AI image workloads without Kubernetes: GPU rental, serverless inference, managed pipelines, and hyperscalers compared. DevOps decision guide for 2026.

ComfyUI slow on M1/M2/M3/M4 Mac? Four fixes: attention mode, memory limit flag, FP16 precision, and CPU fallback. Real generation times across Mac chips.

ComfyUI Manager shows 'This action is not allowed'? Three fixes: security level settings, config.json edit, and CLI flags. Safe vs risky trade-offs explained.

RTX 3060 12GB out of VRAM with Flux? Five fixes: FP8 quantization, VAE tiling, CPU offload, attention optimization, resolution reduction. Real VRAM numbers.

LoRA has no effect in ComfyUI Flux? Six causes: wrong folder, SDXL LoRA, strength value, CLIP mismatch, stale cache, corrupt file. Fix checklist included.

NaNsException in ComfyUI Flux? Five causes: wrong VAE, FP16 overflow, CFG scale, corrupt checkpoint, bad sampler. Systematic diagnosis and verified fixes.

Why Replicate cold starts happen, when they affect custom vs public models, and the exact fixes. Cost breakdown for warm models vs switching providers.

Replicate vs fal.ai vs RunPod vs Vast.ai. Decision matrix for production ComfyUI: latency, cost, cold starts, and DevOps burden compared.

Cold start benchmarks across Replicate, fal.ai, Modal, and RunPod. What causes serverless GPU cold starts, which providers win, and how to eliminate them.

ComfyUI exposes a WebSocket API, not REST. Here is how to use the /prompt endpoint, poll results, and build a reliable production wrapper around it.

How to run ComfyUI in Docker for production: the --listen flag most guides skip, volume strategy for large models, GPU passthrough, and health checks.

RunPod, Modal, fal.ai, Replicate, and Comfy Cloud compared for ComfyUI serverless. Verified pricing, cold start benchmarks, and custom node support. May 2026.

ComfyUI has no built-in auth. Secure it with Nginx, API keys, JWT, rate limiting, and a hardening checklist - before the next botnet finds your port.
