xAI (Grok) setup

xAI provides Grok, a cloud-based reasoning model that the coaching platform uses to analyse your coaching transcripts and generate ICF competency assessments. You need an xAI account and an API key. Usage is pay-as-you-go.

Grok's reasoning model is one of the fastest providers for coaching assessment, completing a full PCC evaluation in under 1 minute while maintaining rigorous, honest feedback.


Step 1: Create an xAI account​

  1. Go to console.x.ai
  2. Click Sign up
  3. Create an account with your email address, or sign in with your X (Twitter) account

Step 2: Add a payment method​

  1. Once signed in, go to Billing in the left sidebar
  2. Click Add payment method and enter your card details

xAI API access requires a payment method. You are only charged for what you use.

Set a spending limit

Under Billing > Limits, you can set a monthly budget to avoid unexpected charges. A limit of $10 per month is more than enough for most coaching use.

Step 3: Create an API key​

  1. In the xAI console, go to API Keys in the left sidebar
  2. Click Create API Key
  3. Give it a name (e.g. "Coaching Platform")
  4. Copy the key immediately. It will not be shown again.

If you lose the key, you can always create a new one and update it in the coaching platform.

Step 4: Configure the coaching platform​

  1. Open the coaching platform and go to Settings > AI
  2. Select xAI (Grok) as your provider
  3. Paste your API key into the API Key field
  4. Choose a model. See Choosing a model for recommendations. grok-4-1-fast-reasoning is the recommended model for fast, honest feedback.
  5. Click Save

To test the connection, open any session with a recording and transcript, then click Generate AI Assessment.

Speed

Grok's reasoning model is exceptionally fast. A full PCC assessment typically completes in under 1 minute, compared to approximately 4 minutes for Claude Sonnet on the same session. This makes it a good choice if you assess sessions frequently.

Avoid non-reasoning variants

Only the reasoning variants of Grok (like grok-4-1-fast-reasoning) are recommended for coaching assessment. Non-reasoning Grok variants carry the same positivity bias risk as other general-purpose chat models.

For context windows, output token budgets, and rate limits, see API limits.

Troubleshooting​

"API key invalid" error​

Verify the key is correct. Go to API Keys in the xAI console and check that the key exists and has not been revoked. If in doubt, create a new key and update it in the coaching platform.

"Insufficient credits" error​

Your xAI account has run out of credits. Go to Billing in the xAI console and add funds or check your spending limit.

Assessment quality seems inconsistent​

Make sure you are using the reasoning model (grok-4-1-fast-reasoning). Non-reasoning Grok variants produce less reliable coaching assessments with potential positivity bias.
