More about this job

Self-hosted chat interfaces give your team one place to talk to several models, with accounts, shared prompts and optional document upload, while you decide where data is stored.

Workflow in 5 steps

  1. Decide which models and what data may be used.
  2. Deploy the chat UI behind your login or single sign-on.
  3. Create roles and disable features you do not need.
  4. Write a short usage policy and share it with the team.
  5. Monitor usage and costs, update regularly and back up the database.

Watch out for

  • Prompts sent to a hosted model leave your machine.
  • Keep API keys, tokens and customer data out of prompts and out of files the agent can read.
  • Agent loops can burn through paid API tokens quickly.
  • Self-hosting makes you responsible for updates and security.
  • Licence to check before commercial use: LobeHub (LobeHub Community License), Open WebUI (Open WebUI License).

Why these warnings?
  • Prompts sent to a hosted model leave your machine. For confidential material use a local model or check the provider's data terms first.
  • Keep API keys, tokens and customer data out of prompts and out of files the agent can read. Use a separate, low-privilege key for any agent.
  • Agent loops can burn through paid API tokens quickly. Set spending limits with your model provider and watch the first few runs.
  • Self-hosting makes you responsible for updates and security. Keep it patched and do not expose it to the internet without authentication.
