Multi-Modal Frontiers & Vector Architecture
Open-Source Visual Language Models
Open-source visual language models bring image understanding and generation to self-hosted stacks with control over data and cost. Quality has risen fast, but tooling, evaluation, and safety are still maturing. The right choice balances capability, hardware, and maintenance burden.
Kernpunten
- Evaluate VLMs on your own images and tasks, not just public benchmarks.
- Check vision encoder quality and resolution limits for your use case.
- Quantize and serve with supported engines; VLM serving is harder than text-only.
- Measure hallucination and grounding on real documents and screenshots.
- Plan GPU memory around both vision encoder and language model.
- Add safety filters for generated and described visual content.
- Track model updates and re-run evals before upgrading.
- Keep a text-only fallback for cases where vision adds no value.
Veelgestelde vragen
Are open VLMs production-ready?
For scoped tasks with evals yes; for open-ended vision work, tooling is still maturing.
Do VLMs need special serving?
Yes, vision encoders and image preprocessing add memory and latency.
How do I reduce hallucination?
Ground answers in OCR and structured extraction, and validate outputs.
What hardware do I need?
Depends on model size; small VLMs run on one GPU, large ones need more.
