Three settings under Models in your agent’s Advanced tab decide how your agent thinks and how it hears. Most businesses never need to touch them, and the defaults are chosen to be fast enough for a phone call. Change them when you have a specific problem: replies that are too slow, or reasoning that is not good enough for a complicated conversation.

​
Before you start

  • An agent that has taken real calls, so you have something to compare against.
  • Ten minutes, and a phone.
  • A specific complaint to fix. Changing models without one usually makes things worse.
  • You will be working in the Models section of your agent’s Advanced tab.

​
Steps

1

Open the Advanced tab

Open your agent, go to Advanced, and expand Models.
2

Choose the AI model

Click AI Model. The list is grouped by provider and filtered to the models available in your workspace region, with a short description of each.This is the model that decides what your agent says. A larger model reasons better and answers more slowly, and on a phone call the delay is the thing callers notice.
3

Choose the transcriber

Click Transcriber. This is what turns the caller’s speech into text before your agent reads it.If your problem is that your agent misunderstands callers rather than answering badly, this is the setting to change, not the model.
4

Set the thinking effort

Thinking effort runs from Off through Low, Medium, High, Extra High, to Max. Higher effort lets the model reason more before replying, and every step makes replies slower. Off is the fastest.On voice calls the available range is capped, because a caller will not wait. Only the levels a model can sustain in a real time conversation are offered.
5

Save and call it

Save, then call your agent and run through your most complicated scenario. Time the pause before it answers. See Test your agent yourself.

​
You will know it worked when

Your agent answers your hardest question correctly, and the pause before it speaks is short enough that you do not wonder whether the line has dropped.

​
The trade off, in one table

The last two are worth reading twice. Most problems that feel like the model being not clever enough are actually a missing document or a contradictory instruction, and no model setting will fix those. See Why it answered wrong.

​
How to change these safely

Change one setting at a time and call your agent after each change. Model settings interact, so changing the model and the effort together tells you nothing about which one helped. If your agent is live, use a version rather than editing in place, so you can compare properly and switch back in one click. See Save and switch agent versions, and A/B test two versions of your agent if you want the two running side by side on real traffic.

​
What else you can do here

​
If it did not work

Replies got slower and no better. Put Thinking effort back down. Effort buys reasoning on genuinely hard problems and costs you latency on every ordinary call, which is a bad trade for a receptionist. The model list is short or empty. Models are filtered to your workspace region. If the list is empty, your region has none available and support can tell you what is coming. Email support@brilo.ai. You cannot select the effort level you want. Voice calls cap effort at whatever the model can sustain in real time. The missing levels are not available for voice, by design. It still misunderstands callers. Change the transcriber, turn on Advanced Noise Cancellation, and add the words it gets wrong to your vocabulary. See Sound quality and background noise. It still gets facts wrong. That is knowledge, not the model. See Why it answered wrong.

FAQ

The default, unless you have a specific complaint. Open Advanced and expand Models to see what your workspace region offers, with a description of each. Change it only when replies are too slow or your agent cannot follow a complicated conversation.
Usually Thinking effort set higher than the call needs, or a long answer that takes time to produce. Lower the effort a step, and set Answer Length to Concise. Note this is separate from the deliberate pause your agent leaves after you stop talking, which is Patience Level.
It gives the model more room to reason before it replies. Higher effort means better handling of multi step requests and slower responses. Off is fastest. On voice calls the range is capped to what can be sustained in a live conversation.
It converts the caller’s speech to text before your agent reads it. Change it when your agent misunderstands what callers say. If it understands fine but answers badly, the transcriber is not your problem.
No. Invented facts come from missing knowledge, and a bigger model invents more fluently. Upload the facts and tell your agent never to quote anything not in its knowledge. See Why it answered wrong.
Not today. You choose from the models Brilo offers in your region. Email support@brilo.ai if you have a requirement that needs it.
Change it on a version rather than in place, so you can compare and roll back in one click. See Save and switch agent versions.
