Trusted by teams at over 1,300 of the world’s leading organisations

Why custom LLMs?

Your organisation has already invested time and resources into selecting the right AI models for your needs. Maybe you've negotiated special rates with specific vendors, or perhaps your security team has approved certain models only.

Custom LLM (BYOK) means you don't have to start over or compromise on those decisions. You get to keep using your chosen AI models while gaining all the workflow management, quality control, and governance features that XTM Cloud provides.

FAQs

How does Custom LLM (BYOK) work with our existing AI vendor contracts?

Custom LLM (BYOK) uses your existing credentials and API keys, so your current vendor relationships and pricing agreements stay exactly the same. XTM Cloud simply provides the orchestration layer on top of your chosen models.

Can we use different AI models for different types of content?

Yes, you can configure which custom LLMs to use at the workflow level. This means you might use one model for technical documentation and another for marketing content, all managed through the same XTM Cloud interface.

What happens to quality control when we use our own models?

Your custom LLMs work alongside XTM Cloud's quality scoring, thresholds, and routing logic. This means you still get the quality management features you need, just with your preferred AI models doing the translation work.

Is our data secure when using Custom LLM (BYOK)?

Your data security depends on the AI vendors you've chosen and your own security setup. XTM Cloud simply passes requests to your models using your credentials, so you maintain the same level of control you already have.
