A vision-language model joins a visual encoder to a language model so you can ask plain-language questions about a picture or clip and get a written answer. VLMs increasingly replace custom detectors for tasks where flexibility beats peak speed.

AI for Video: A Complete Guide to Intelligence in Video Products: From Real-Time Pipelines and Agents to Serving, Cost, Compliance, and Verticals
A VLM can replace several custom detectors with one prompt, but per-frame cost and latency decide whether that works in production. Volume 7 covers the VLM in detail as a production component: open versus hosted vision-language models, serving infrastructure, cost per stream-hour and the real-time budget for video inputs. Written by Nikolay Sapunov, CEO at Fora Soft.
