Using Grok (xAI) as the brain for a business chatbot
Grok is xAI's language model, available through an API that follows OpenAI's format, which makes it straightforward to use as a chatbot brain. On Convo360 you pick it per agent and run it on your own key, exactly like OpenAI, Claude or Gemini.
- Grok's API mirrors OpenAI's format, so switching is a dropdown rather than a rebuild.
- Judge a model on your own transcripts, not on benchmark scores.
- Model choice matters less than your knowledge base and your prompt.
- Keep a second provider configured so an outage is a setting change.
What Grok is, in practical terms
Grok is the family of language models built by xAI. For a business chatbot, what matters is not the branding but three ordinary questions: is it good enough at the task, what does it cost, and how hard is it to use.
On the third, Grok is unusually easy. Its API follows the same shape as OpenAI's, which means any platform that already supports OpenAI can support Grok with very little work. On Convo360 it appears alongside OpenAI, Claude and Gemini as a choice per agent.
On quality, the honest answer for routine support work is that the leading models are close enough that your knowledge base and your system prompt matter more. A bot answering questions about your return policy is limited by whether the policy is written down clearly, not by the model's reasoning.
Where models genuinely differ is at the edges: long documents, unusual languages, and complex multi-step reasoning. Most support conversations sit nowhere near those edges.
Choosing between providers honestly
Ignore benchmark leaderboards. They measure tasks that have almost nothing to do with answering a customer asking whether a kurta is available in XL.
Test on your own material instead. Take thirty real customer messages from last month, run them through two or three models with the same prompt and the same knowledge base, and read the answers.
| Look for | Why it matters |
|---|---|
| Does it refuse to invent facts | A confident wrong answer is worse than no answer |
| Does it handle Hinglish naturally | Most Indian customers mix languages mid-sentence |
| Does it stay on topic | Off-topic drift is the most visible failure to customers |
| Is it concise | Long replies read as generated, however accurate |
Thirty real messages will tell you more in an hour than a week of reading comparisons.
Running it on your own key
Convo360 is a bring-your-own-keys platform, so you hold an account with xAI, generate an API key, and paste it into the provider keys settings. Usage is billed by xAI directly at their published rates with nothing added.
The practical advantages are the ones that matter over time. You see exactly what your AI costs rather than a bundled per-message price. You can set your own spending limits with the provider. And if you ever leave the platform, the account and its history remain yours.
Once the key is saved, the model is a dropdown on each agent. A business can run a cheap fast model for routine WhatsApp support and a stronger one for a complex sales agent, on the same account.
When to switch, and when not to
Do not switch models because a new one was announced. Switch when you have a specific complaint your current model causes.
Good reasons: it invents details your knowledge base does not contain, it handles your customers' language badly, it is too slow at peak, or it costs more than the value it adds. Each of those is testable.
Bad reasons: a benchmark, a launch post, or a general sense that something newer must be better. Switching resets your understanding of how the bot behaves, and that understanding is worth real money.
What is genuinely worth doing is keeping a second provider configured and tested. Model APIs have outages, and being able to change a dropdown during one is far better than discovering during an incident that your only key is with the provider that is down.
The things that matter more than the model
Three factors affect answer quality more than provider choice, and all three are within your control.
The knowledge base. A bot cannot explain a policy nobody has written down. Most disappointing bots are disappointing because the source material is thin, contradictory or out of date.
The system prompt. Three lines describing your business, your tone and how to handle bad news will change replies more than any model upgrade. Be specific about what the bot should refuse to do.
The handover rule. Knowing when to stop is a design decision, not a model capability. Decide which topics always reach a human, and make that explicit.
Teams that fix these three get good results from any of the current models. Teams that do not will be disappointed by all of them.
A sensible setup for an Indian business
Most businesses do well with a small, fast model for routine support and a stronger one reserved for where it earns its cost.
Put the routine WhatsApp agent on the cheapest capable model you have tested, since order status, opening hours and policy questions need retrieval rather than reasoning. Put a sales or advisory agent on something stronger, where a better answer converts.
Keep both keys configured, set a spending alert with each provider, and re-run your thirty-message test once a quarter. Prices fall, models improve, and the right choice in January is often not the right one in July.
Above all, keep the test material. Comparing a new model against the same thirty messages is what turns a switching decision from an argument into a ten-minute exercise.

Frequently asked questions
Is Grok better than GPT or Gemini for support?
For routine support work the leading models are close enough that the difference rarely shows. Test all three on thirty of your own customer messages, because the answer depends far more on your content than on the model.
Do I need a separate xAI account?
Yes. Convo360 runs on your own keys, so you hold the account with xAI and pay them directly at their published rates. Nothing is added to the price by the platform.
Can different agents use different models?
Yes, and most businesses should. A cheap fast model handles routine support well, while a stronger one is worth its cost on a sales agent where a better answer changes the outcome.
What happens if my provider has an outage?
If a second provider is configured, changing the model on the affected agent restores service immediately. This is the main practical reason to keep more than one key saved and tested.
Does model choice affect my WhatsApp costs?
No. Meta charges per conversation regardless of which model wrote the reply. Model choice affects only the bill from your AI provider, which is a separate and usually much smaller amount.
