Koala uses a language model to explain your cost data — to narrate insights and answer chat questions in plain language. The model is configurable per tenant.

​
Two ways to power the AI

You configure this in Settings → AI Providers, and there are two modes:

SaaS mode

Use the Koala-provided model. Nothing to set up — usage is capped by your plan, and a banner shows tokens used, your limit, and tier. When you reach the cap, Koala prompts you to add your own key.

Bring your own key

Add your own provider key (OpenAI by default) for uncapped usage on your own account. Manage, test, and reset usage from the same tab.

Your API key is encrypted at rest and shown only as a masked hint. Use Test to validate it, and view or export token usage from the AI Providers tab.

​
The evidence guardrail

The most important thing to understand about Koala’s AI is what it does not do:
The model never invents numbers. Every figure in an insight or a chat answer comes from SQL over your own data. The language model only turns those verified results into readable explanations — it is given the evidence and asked to explain it, never to produce the numbers itself.
This is why Koala’s answers are safe to act on: each one can be traced back to the exact query and aggregates that produced it. See How it works for the full pipeline.
