Enterprise customers can run Callers agents on their own large language model (LLM) instead of Callers’ default models. Your agents keep working the same way, with the same scripts, actions, knowledge base, guardrails, and post-call analysis, but the conversation is generated by a model endpoint or provider account that you control.
Bring your own LLM is available on enterprise agreements and is configured together with the Callers team. There’s no self-serve setting in the dashboard.

​
Why bring your own LLM

  • Data residency and compliance. Keep model processing in a region, cloud, or provider account approved by your security and legal teams.
  • Existing provider contracts. Use the commitments, rate limits, and terms you already have with a model provider.
  • Fine-tuned or private models. Use a model trained on your domain, terminology, or tone.
  • Cost and usage control. Track and manage model usage in your own provider account.

​
How it works

Callers keeps handling telephony, speech recognition, voices, turn-taking, actions, and analytics. Only the model that generates the agent’s replies changes.

​
What to prepare

Real-time voice conversations put strict demands on the model. Before you contact us, gather:
Voice agents need low-latency streaming to avoid awkward pauses, and tool or function calling to run actions such as transfers, bookings, and HTTP requests during the call. A model without these may not work well, or at all, for voice. Text and email agents are less sensitive to latency.

Get started

1

Talk to us about your provider

Book a meeting or email support@callers.ai. Share the details from What to prepare.
2

Confirm compatibility

The Callers team reviews your model and endpoint and confirms whether they fit your use case.
3

Connect and test

We connect your model to your account. Test your agents with test calls and chats and compare the results with your current setup.
4

Roll out

Once you’re happy with quality and latency, move live traffic to the agents that use your model.

​
FAQ

Talk to us about your provider. Compatibility depends on the model’s latency, streaming, and tool-calling support, so we confirm it case by case.
Scripts, actions, and settings stay the same. Different models can behave differently, though, so test your important flows and adjust prompts and instructions if needed.
Discuss your rollout plan with the Callers team during setup.
