Frequently Asked Questions

Discovery usually takes 1–2 weeks. An agent or LLM MVP often lands in 4–8 weeks depending on scope. Full production rollouts vary by integrations and compliance needs.

Yes. We support private deployment, local/open models, and routing between providers based on latency, cost, and data residency requirements.
