Reviewer scorecard
“Gen-4 changed my content workflow. B-roll that used to take a day to shoot now takes 30 seconds to generate. The consistency improvements make it actually usable.”
“Stable Diffusion with ControlNet and LoRA fine-tuning gives artists more control than any closed model.”
“Still not perfect — you'll get weird artifacts and the occasional uncanny valley moment. But for 80% of use cases, it's good enough. And 'good enough' keeps getting better.”
“Company instability and leadership changes are concerning. The open-source models are great but the company's future is uncertain.”
“Video was the last holdout of 'AI can't do this well enough.' Runway just broke through. The implications for content creation, advertising, and filmmaking are seismic.”
“Open weights mean you can self-host, fine-tune, and customize. ComfyUI + Stable Diffusion is the power user stack.”
